How to Diagnose a Faulty Driveshaft Center Support Bearing
Автокөліктер мен көлік құралдары
How to troubleshoot a faulty driveshaft hanger bearing. So in this particular video I will be using my 1997 BMW 540i as an example, but this diagnosis can be applied to other vehicles with a similar driveshaft setup. Other manufacturers which use hanger bearings and is not limited to is Toyota, Dodge, Mitsubishi, Cadillac, GMC, Chevrolet, Mercedes, etc. A driveshaft hanger bearing, also known as a center support bearing serves the purpose as the name states. In short, it supports the driveshaft. It not only keeps the driveshaft neatly tucked away within the underbody of the vehicle, but it also helps achieve the correctly angles for the universal or constant velocity joints, this vehicle has both in the driveshaft. If the angles are incorrect, this will cause excessive wear on the joints, possible vibrations, and lead to premature failure. The exterior will have a steel frame, next is a rubber damper which keep the driveshaft somewhat floating dealing with the movement from the body, suspension, or drivetrain. And finally the center used a bearing which allows the driveshaft to rotate freely and smoothy. They can fail in a couple different ways, either the rubber eventually cracks which will cause vibrations or in a worst case scenario clunking if it’s badly worn. This can be noticeable at certain speeds or when starting off from a stop in drive or reverse. Besides the rubber being somewhat worn, the bearing was also coming to the end of it’s life too. You can hear some clicking clicking on camera hopefully and you can see it also turned fairly easy. A new bearing should be somewhat stiff when turning. The other way it can fail is the bearing can eventually wear out. A worn bearing will create a clicking or growling noise, depending on how bad it’s worn. A faulty bearing typically starts out as a clicking, eventually growing to a growling sound which can sometimes be felt through the body of the vehicle and the noise will increase with speed as the driveshaft turns faster. Mine wasn’t overly expensive, I didn’t buy one directly from BMW but instead the manufacturer who produces them for BMW. #BMW #BMW5series #autorepair

By far, this is the absolute BEST video in terms of thoroughness, ease in giving instructions, tonality, pace, directness, camera positioning and explanation for repairing a vehicle I have ever seen on KZread or anywhere else. I am amazed. Thank you kind sir. Your channel is very much appreciated.

Thank you so much for the kind words and feedback, comments like yours are very much appreciated!
I love how you made this simple and clear, great information clear vid!!
Beautiful custom exhaust system
In this video u said push foward the bearing 2-4 mm - I’m kinda lost with that would u mind explaining?
This helped me out, I’m getting a vibration from my shaft randomly depending on turning angle
Any idea why it would clank on a brand new bearing? It clanks only while braking from over 20 mph.
Would a faulty support bearing cause a knock on acceleration?
Thnks helps alot to understand, u did a great job.

Aren’t they the best cars? I got sideswiped in mine, and also had a deer slam it rack on my driver side window and she is still going. They really are built like little solid tanks.
My E36 makes a sound like a bunch of really angry crickets when I let off the gas. Could this be my issue?
Love the vid, very detailed! :D
Hey great video. I just did my rear driveshaft on my 2007 x3 e83 3.0si .. I'm getting a whineing / whistling noise form 25-30 mph when accelerating and decelerating. bad center support bearing.? The driveshaft came with the Quibo and the Center support bearing. Sounds like a Power Steering pump but that's not it. Thanks for any input.

super late but are you running an aftermarket intake by chance?
Awesome work, and thank you for doing this. I wonder if you can help me, my e39 is making a clunking noise while accelerating, subsides whem removing foot off pedal, with a slight vibration, nothing serious. The car has automatic transmission, most noticeable first through third gear. I was leaning to a support bearing issue as it shifts smoothly, and makes no noise anywhere near the front of vehicle, the sounds comes strictly from mid car to rear. What is your opinion? Thank you!!

That almost sounds like it could be differential or subframe bushings, I would look at the condition of those first.

Hi, I own chrisler 300c 3.5l with automatic transmission, and I have a problem of impact when I put the gear in R, as if the driveshaft has a free kick, sometimes a blow to the rear of the vehicle when switching speeds, the gearbox is ok, works perfectly. What can be a problem?

so, would you say that that vibration ,humming, roaring sound coming from under my toyota sequoia 04 as it runs ,may be my drive shaft?

yes, if it doesn't change pitch when you whip the car around on the road, otherwise could be a wheel bearing
Why do these use support type of bearing as I've never had a problem with Grand Cherokees and yet my Cayenne rubber seems to have perished and now the bearing seems shot.

Depends on the design, quality of components used, etc. If your Cayenne had previous work to the driveshaft area, then it could have been misaligned too.

My 2013 shift failed; bearing and u-joints
I have had a Subaru forester 1997 (automatic) from new (approx. 70,000 miles on the clock), that has been great for all the years with very little to do other than annual services. However, recently I have had a lot of vibration & shuddering on the wheels when making slow tight turns (left or right) but never on the straight. It is difficult to identify which wheels the noise or shudder comes from and I don't feel much through the steering wheel. I have had all differentials replace that has reduced the frequency but not eliminated the problem. We hope it isn't the automatic gear box but has anyone got any ideas what to do next.

You may have a failing wheel bearing or cv joint in one of the axles. I do have a video for troubleshooting a faulty wheel bearing. For a cv joint, it may have a ripped boot which allowed in dirt and let grease escape. It won't be the transmission failing.

@@4DIYers SHE LIVES AGAIN!!!!!!…..an interesting item at 3 minutes to 4:40 minutes in the attached video ( kzread.info/dash/bejne/eYRrtqunpJfXaJc.html )..... this was exactly what I experienced with my 1998 Subaru Forester but no-one could diagnose the problem.... £3k was spent/wasted with my Local Subaru dealer trying to fix it... but to no effect. Then I found the attached video link.... and then I found a good mechanic willing to do the work..... and yesterday we got our car back (with new solenoid in the transmission) and she runs great..... Well worth the effort.... these Subaru's can go on forever (almost) George (London, UK)
What happens if you do not place back any bearing and just remove that support.??

The driveshaft will flop around causing damage.
I can hear a humming noise coming from the rear, it increases as I speed up.

For me it sounded a lot like a wheel bearing… it was very frustrating to replace 2 wheel bearings and then still hear something wrong… then later the hanger bearing wore through and it felt like the drive shaft was slammin the bottom if car on the freeway.. pretty scary.

It's kind of hard to show what a clunking or vibration would feel like on a video. The rubber damper was still in decent condition for this particular vehicle, the bearing was actually faulty but I only found that out until the driveshaft was removed. The bearing wasn't in bad enough shape to show up during a drive. You can hear the noisy bearing when I'm spinning the assembly. The original intent for the drive shaft being removed was for a faulty flex disc.

Front wheel drive cars can have more cv joint issues and easier to wear or damage the engine or trans mounts.
