Yes it works well ive done that back in the 90s. Brand new motor home that vibrated so bad it would open cabinet doors inside. I put a couple hose clamps on the drive shaft and kept adjusting until it was nearly gone. They had just been in a dealership in Florida where they had a new rear end installed under warranty. I fixed it with a couple of hose clamps and amazed everyone.

Yes, this is dangerous. I suggest a pair of jack stands under the axle and a second pair of jack stands under the frame about 1/4" - 1/2" below the frame so the weight is on the axle. If it slips off the second set of jack stands should catch it. This works but please be careful. Double check the slip joint that goes into the end of the transmission if this is a one piece driveshaft. look for wear and put some lithium based grease on the splines. If the vehicle is raised up with larger tires you may need to check the operational angles on both U-Joints. If this is a two piece driveshaft and the driveshaft has been separated in the middle it is possible to put these back together on the wrong splines affecting the phasing of the driveshaft. Normally the driveshaft Yokes should all be in alignment with each other.

video was very useful, i had to replace the center bearing on a two piece drive shaft on a Ford Territory. It went fine until i realized i didn't mark the splines in the center as to where they went back together. the water trick didn't work as well since it was supported and didn't transmit the same shock waves except i could feel it from the driver seat. so i jacked up the rear wheels, marked the spline i was on and drove it similar to your setup with the wheels in the air. after moving the splines around i found the one sweet spot where it didn't vibrate anymore. thanks for the ideas on what to do.

It's highly unusual that a front CV axle would need balancing but if it worked great. Often CV axles will vibrate on acceleration and smooth out when you let off on the gas. This is often caused by a binding inner CV joint. Don't let the fact that you just replaced the axle fool you. I have seen defective replacement axles. Another thing to consider that effects front CV axle alignment is defective and sagging motor and transaxle mounts and misaligned subframes.

When you changed your center bearing you had to separate the two piece driveshaft. Did you mark the two halves and return them to the same location?

With the tires on how do you know if the vibration is from the driveshaft and not from an out of balance wheel. Also, the axle should be down on the jack stands from the get go to get an accurate reading as the stands will remove a lot of the movement from the imbalance.

@DrivelineMaster

5 жыл бұрын

Ideally the tires should be removed however when visual vibration is improved by changing the location of the hose clamps this is verification that the hose clamp location is influencing the vibration and improving the driveshaft balance. Driveshafts are not a common cause for vibrations and normally the first steps in isolating a vibration is to have the tires balanced. Since I knew the tires were in balance I decided it was not necessary to remove them. I start out with the wheels and suspension suspended for ease of video visuals however if you watch closely you will see when I perform the final vibration analysis the suspension is compressed with the axle resting on jack stands. This is important because it ensures the driveshaft and u-joint angles are at proper operational angles.

Tires need to be in balance before performing this job. If the tires are removed before doing this then the brake drums or rotors should also be removed before hand. It's not likely that the hose clamps will come off. It's not very common for a driveshaft to be out of balance but just in case it can be re-balanced using this technique. After balancing the driveshaft using this technique and confirming that this solved the vehicle vibration problem the driveshaft can be removed and sent to a professional balance machine shop to have the counter balance welded to the driveshaft with full confidence that the vibration problem is solved.

Hello, Driveshaft Balancing. Thank you for a great video. I have a 2008 Jeep Patriot with a manual transmission and a front-wheel drive. I replaced the front CV Axles, intermediate shaft (passenger side), front struts/shocks (now the Patriot is a little higher because the new struts/shocks assemblies are higher than its old strut/shock assemblies), motor and transmission mounts. Here is the problem: I can visually see how the passenger's-side CV axle is rotating out of center (and so is the driver's-side CV axle, but not as much as the passenger's-side) AND the vehicle has a sideways vibration between EXACTLY 20 miles per hour and 30 miles per hour. Below 20 m.p.h. and above 30 m.p.h, the Jeep runs and drives flawlessly. Question 1: Will balancing both CV axles eliminate the vibration? Question 2: How do I know that a motor and/or transmission mount may be the culprit?

You typically would not balance FWD half shafts. Is the vibration load sensitive. In other words does it come and go or get better or worse if you are accelerating or letting off on the gas? If so, the problem is driveline related. If not, it may not be driveline related. Where do you feel the vibration? In the seat of your pants or more in the steering wheel. Steering wheel vibration is more likely tires, wheels, alignment, steering or suspension related as compared to driveline related. I wouldn't be trying to balance the halfshafts and instead I would be looking for another cause for your vibration.

Additionally, inspect the driveshaft to make sure the balance weights have not fallen off and there are no dents in the shaft.

Most driveshafts will have counter weights at the front and rear but often the front does not have enough access room to get into it so normally only the rear is done. The rear is also where most of the vibration will take place. Normally you can perform this process on the rear and solve the balance problem and the front does not need to be done. Once I discover that my balance job has solved my problem I will often remove the driveshaft and send it out for profession balancing but it's not really necessary.

Driveshaft vibrations are normally felt through the seat of your pants and not so much in the steering wheel. Steering wheel vibrations are often caused by tires and wheels being out of round and out of balance. Steering wheel vibrations can also be caused by looseness in the steering or suspension system. Have your steering and suspension inspected and have your tires and wheels inspected and balanced. If the vibration only happens when braking then the problem is most likely brake rotors that are not parallel or there is too much thickness variation. Replacing and or machining the rotors normally take care of this. Brake drums can sometimes cause this but it's rare. With big tires and rims I suspect this is your problem. The bigger the tires the harder they are to balance. If you have a small sidewall on the tire in order to make the large rims fit this makes the road surface more noticeable and the road imperfections can be felt more by the vehicle suspension making it difficult to absorb vibrations preventing them form being felt by the passengers.

Samuel, I will need to do a little sleuthing through Q & A in order to help you. A driveshaft that is out of balance is abnormal and not likely the problem but as a diagnostician nothing ever gets ruled out. Where do you feel the shake? In the steering wheel or more in the seat of your pants? Is this a 4 wheel drive or 2 wheel drive truck? are these tires of normal factory size or oversize tires? Are these tires aggressive off road tires or standard tires? Have you replaced the rims with something that is not factory size? A clunking noise when you turn the wheel could be something loose in the suspension or steering. Any looseness should have been caught by the pre-alignment inspection. You should have a front end expert inspect your steering and suspension with a fine tooth comb. Do you hear the clunk if you turn the wheel while parked? If so, crawl under the front of the truck while a friend turns the wheel back and forth. See if you can identify where the noise or looseness is coming from. If the clunk is only when driving and you have a 4 wheel drive the problem could be in one of the axle shafts. While the front end specialist is inspecting your front end have them look at the driveshaft. If there is a 2 piece driveshaft they should inspect the center bearing along with the u-joints. Here is another thought questions. Is the vibration greater when accelerating as compared to letting off on the gas. In other words is it gas pedal position sensitive? While the suspension is being inspected have the technician inspect your rims for dents and run out. Have them look for wheel weights that may have come off throwing the tire out of balance. Have them look at the driveshaft to see if they can tell if the balance weights have been knocked off somehow. Lets start with these questions and based on your answers I may be able to help.

Shouldn’t this be done with wheels off and rotors or drums secure, to prevent false readings from tires?

Yes. if you want to take the extra steps. If you really truly want to only balance the driveshaft the brakes should be removed including the drums or rotors. If you think about it though when you drive down the road your tires will be on and if you start with balanced tires this works just fine with the tires on. I have a really expensive balancing tool and with their instructions they don't mention taking the tires off so I just left mine on.

I hate running wheels off the ground and ive been wrenching for a good while. Even on big blocks, it seems like my truck would shake itself off. Thinking about shortening a couple axles myself and wanted to see if there was a way to permanently balance them myself. If i used the intended weights and tape carefully evenly measured, think there would be much difference after welding and removing tape?

This technique must be done using EXTREME CAUTION!. Even running on a hoist with quality jack stands is dangerous and scary however there is no other way to do this short of taking the driveshaft to a specialty shop for balancing. Question 2, that balance might change after welding depending on how much welding material you use. You won't need much to hold the weight in place. If you keep the welding material to a minimum you should be OK.

@@DrivelineMaster i gotta be honest, i do enough stupid things already and if can get it balanced for a hundred bucks, ill happily go that route. Had been fighting with the truck for a few hours and was a bit tired by the time i saw video. Back to full cognition and its all nope! Lol Had to cut 1 3/4" off the inside of a split yoke this morning to get front drive shaft comfy after an axle upgrade. Took just under 1/3rd , almost 1/4 of the total splined portion off. Finished it by hand files.

does the method of holding chalk or a sharpie etc near the spinning shaft have to be done on a portion that is 100% true? i.e. if spinning the driveshaft via my foot on the tire in neutral i find a high spot of .004" then would this contact the marker? id imagine this would also be consistent with a heavy spot but not necessarily. perhaps a marker should be clamped to a scissor jack and this should be raised up to where it is almost touching that high spot? or, perhaps this should only be done on a perfectly true area of the shaft? im guessing that a heavy spot as shown in the video will naturally cause just enough flexation of the shaft or components to contact the marker

@DrivelineMaster

Typically the chalk is used about 6 - 8 inches from the rear u-joint and or the front u-joint to find the heavy spot. The high spot using a dial indicator may not be the heavy spot. The driveshaft becomes slightly distorted from the heavy spot the faster it spins. I wouldn't fasten the chalk to a jack because when it touches it is ever so slight and you need to feel it. It's really easy to touch too much and end up marking 2/3 of the way around on the shaft. It truly is the slightest of touch. You could use the jack to rest your hand or arm as you slowly bring the chalk closer. Chalk works better than a sharpie.

@dangerdavefreestyle

Жыл бұрын

a scissor jack with a sharpie or chalk in this case could be positioned and raised in .001" increments till it is almost touching the shaft. as slow rotation occurs, there will be an area with a gap of say .005" and one where the tip touches and drags as it goes around. then it comes around and theres that gap again, spin it again now its dragging, you can measure runout this way. no dial indicator. a scissor jack, cclamp, and ruler, feeler gauge set. so youre saying this area thats draggin youd think would be heavy but its possible there is a heavy spot elsewhere 270 degrees from where you are at with making contact with a marker. so if you now spool it up to high speed, the high dragging spot may or may not be the heavy area, so i dont see any way you are going to probe only the low (gap areas) without touching the pesky false high spot. youd want to see if the amplitude of one of those low spots is acting eccentric and youre limited to only being able to come in contact with the certain spot of an egg shaped (exxagerated) shape. so the way i see it there is no possible way that your way will pinpoint a heavy (whipping) area of mass being a flung around eccentrically and putting your hose clamp with weight on the area you think is heavy which is not necessarily heavy is why you have to move the hose clamp around a dozen times which is exhausting. i just want to know the right spot to put a weight, and only vary that weight if necessary, take some off or add some on. (in grams).

@DrivelineMaster

You may very well be right. What I do know is that this works and has been working for the 40+ years I have been in the automotive field. If you saw the first place I placed the clamps I was really close to being in balance and I only moved them a few time to see if I could dial it in a little better and to demonstrate this technique. Always worth the extra time in my book. Also note my chalk mark was almost 180 degrees from the offsetting weight I used to knock the driveshaft out of balance just for this exercise. As to using chalk, scissor jack and a feeler gauge for me it would be 10 times faster (and more accurate) to just use a magnetic base and a dial indicator to find the out of round high spot. a round shaft that is out of round by .002" - .005" is far from egg shaped and without a gauge it would be undetectable. Just because the shaft is .002" out of round it doesn't mean that the mass of the tube isn't slightly thicker or heavier in a different spot on the shaft. Feel free to try your idea it may just work fine. I always return to the fact that this is a tried and true method that always works if you want to balance the shaft on the vehicle. Often if I find this solves the vibration problem I will remove the driveshaft and send it to a balance shop. I leave this option up to the customer. Good luck.

If this solves the problem I then suggest to the customer that the driveshaft be removed and sent to a professional shop to be balanced.

Fantastic video mate! I have a vibration at high speed around 80-90 kph and it’s throttle dependent. Very distinct when throttle on. It’s like a on-iff vibration, not a continuous one. I had my oversized tires balanced 3 times already. What are your thoughts mate. Any help is appreciated. Subbed by the way.

@DrivelineMaster

3 жыл бұрын

Any vibration that is throttle sensitive is directly related to a driveline problem. This won't be tires or suspension. Before trying to balance the driveshaft remove it and inspect the u-joints carefully because it sounds like one or both of them might have a slight amount of binding. If your driveshaft has a center bearing make sure it is in good condition. Just prior to you noticing the vibration did you have any service work that would have required the technician to remove the driveshaft? If you have a two piece driveshaft (one with a center bearing) and the driveshaft was separated in the middle of the driveshaft it's possible to put it back together in the wrong position. This will cause a phasing problem and induce vibrations. Additionally, you mentioned oversize tires and rims. Was the vehicle ride height raised to accommodate the larger tires? If so, you could be subject to excessive u-joint angle vibration. I started but never completed a video on how to measure u-joint angles. It is preferred that the u-joint not operate at more than 3 degrees and that the angle difference between the front and rear u-joint not be more than 1/2 of a degree. If you don't know how to do this, find a technician that does. If this is a truck that has been raised up to accommodate large tires you may need to adjust the differential pinion angle to correct problems with the u-joint angles. If the truck is raised up really high you may not be able to get the u-joints under 3 degrees and if everything else is checked, adjusted best possible you may not be able to get rid of this vibration because of excessive u-joint operational angles. Good luck mate.

Don't forget about the front driveshaft. You may need to remove the driveshafts to check the operation of the u-joints. They should rotate smooth in both directions without any free play. Any sign that the movement is not smooth would point to this being your culprit. If you have a front driveshaft you may have a double cardon joint that will need careful inspection because they also have a centering ball that can go bad. Don't overlook your transmission and engine mounts or even the control arm bushings for your front and rear differential. Anything out of alignment or that can move under load can change the driveshaft operational angle which can cause vibration.

I just want to be clear because I can't stress this enough. You took the driveshaft off the vehicle and checked each u-joint by hand to make sure they moved freely with zero binding or stiff spots. This is important because the vibration you are describing is more likely a binding u-joint than it is an out of balance driveshaft. If they are all good now that I have expressed the importance of checking the u-joints while the driveshaft is off the vehicle and you have verified the integrity of the engine, trans and diff mounts then you can try to balance the driveshaft but I can't guaranty it will solve your problem. I basically leave the balancing of the driveshaft to the very last thing I try. I want to check everything else first. Then if everything else is confirmed to be good I proceed to balance the driveshaft. Good luck.

My prop shaft bearing kept failing and i did not know why. Replaced the transmission and rear axle because i thought it was a bearing there, not realizing the new prop shaft bearing had failed prematurely. I figured it out once i replaced the bearing support rubber to a stiffer one (incorrectly manufactured). Then the vibrations were really strong in the car at around 40 mph. It also made a low frequency sound as if the subwoofer was playing at 30 hz or something. First then i realized what was the root of the problem. It should have been apparent when looking at the prop shaft, that the balance weights were damaged from rust. While i thought then this was no biggie, now i realize the bad balance is putting a huge load on the bearing, like a hammer smashing it 1000 times per minute, and eventually destroys it. Now i've followed this video, but i did not use a glass of water, i used my fingertips and felt the bearing support crossmember as the car was on cruise control at around 40 mph, finding a spot where i felt the least vibration.

Try removing the front driveshaft and put the truck in 2WD. if the vibration is gone your problem is in the front driveshaft. You can try removing the rear driveshaft and put the truck in 4WD high and drive on straight road because you won't be able to make turns without the driveline binding. If the vibration goes away the problem is in the read driveshaft. Is the truck raised up? You could be dealing with excessive u-joint angles or the front and rear u-joint angles could be out of sync. Have you had the operational angles of each u-joint measured. They should be within 1/2 of a degree from each other. If you had the center support replace make sure the u-joint yokes are in alignment. this is called driveshaft phasing. If the two piece driveshaft was separated to replace the center bearing. and the two halves were not marked and put back in the same place your u-joints could be out of phase causing a vibration.
