**Update** I refer to the “pinion angle” a lot in this video, but I miss-used that term. “Pinion Angle” is the angle of the differential to 0° - what I kept calling the pinion angle is actually the driveline angle. So my pinion angle was 12° and adding the shims changed it to 16° So my angles: Drive shaft Angle: 22° Pinion Angle: 16° (after shims) Rear Driveline angle: 6° 2.5” suspension lift, 1” body lift, 35” tires

Nice!

If you have a drive shaft with a single u-joint at each end, you want your pinion angle the same as your transfer case angle, or as close as possible. If you're using a drive shaft with a double cardan joint at the transfer case end, you want your pinion angle as close to zero as possible. Make sure you're measuring angles with the suspension compressed under the weight of the vehicle.don't jack up your vehicles and put jack stands under the frame and let the suspension drop, your angles won't be correct.

What I found makes a great center bolt for your spring stack is a nice long allen head cap screw you can get them in serveral lengths and if I remember right 3/8" NF is what I used. The round head goes in the hole in the spring perch and you can tighten them easily with a allen wrench on the headed side and a regular socket on the top side. Most of these are grade 5 so they are a bit stronger then the stock mild steel factory pin anyway. I also used a Nylock nut and lock washer on mine.

Tire balance is an even better place to start😜

Changing the angle of the pinion yoke will also change the angle of the driveshaft

I just wanted to add, now that the axle pinion has moved upwards, your driveshaft angle has also decreased. You should remeasure the driveline to see the difference in the angles.

The operating angle of the U-joint at the pinion is only half the equation. The operating angle at the transfer case U-joint needs to be taken into account also. A U-joint does not produce a constant velocity is it rotates. However, two U-joints operating equal and opposite can cancel out this velocity variation. Then of course, there is the maximum operating angle of any single U-joint. 10 degrees is a lot of operating angle. A complete fix would include dropping your transfer case and reducing the overall angles.

I'm guessing there's vibration you were getting is coming from the driveshaft being to short. That slip yoke is at most 2 in from popping out.

The angle between the driveshaft and rear axle needs to be the same as angle between transmission and driveshaft. Also the angle cant be to steep. Then there should be no vibration couse of angels

What you are reterencing is correct on a "street car" or truck, but lifted 4x4's do not work the same. If the angle is matched at both ends you end up with joint bind on articulation. On lifted off road vehicles we get our pinion pointed directly at the t case outpuf to eliminate vibrations, and also keep it out of harms way when on the trail

Nice hairpiece 👍🏼

Flip your drive shaft around so you slip yoke is on the out put of the transfer case. Sometimes the splines wear and will cause a vibration

The way I do it with moderate lift and drive shaft with u joints on each end,,I use a digital angle finder,,put it on the face of either the tail shaft or the pinion and zero it out,,then check it on opposite,ther is your degree shim you need to make them parallel

Forgive my ignorance as I don’t know an awful lot about differentials. But having the rear pinion angled upward toward the driveshaft- couldn’t an excessive amount of upward tilt starve the pinion of oil?

so you said your final angle was 4* . Did you do the math on both angles again? If you bring the pinion up 4* the driveshaft will move about 2* up and that will equal 6*.

So, what changed with the vibration? Did the shims help???

In a ujoint on each end driveshaft,,the output shaft and pinion needs to b parallel to each other,,as long as you stay in a moderate lift situation,,the way I did it,,was take a digital angle finder,,I zeroed it out on the pinion and then put it on the tail shaft,,boom,,gave me the degree shim to use,,did it visey versy,,boom same thing

If you rechecked driveshaft angle that number would have changed too.so you got more than you thought.

Ya think it’s 16* drive line angle now. Are you running a double cardan drive shaft?

Not here to bash your channel but your way off on your approach, the only angles that matter are the transmission/transfer case angle and differential pinion angle and they need to cancel each other out. That being said the more degrees you have the more precise the cancellation needs to be, or go to a CV joint on the transfer case and set the diff pinion at 0 degrees. Also if you have a two piece shaft with worn out splines then your ujoints can become out of phase and also cause a vibration.

This dealt with driveline angles, and is not correct. There is no debate among driveline professionals, The pinion and the differential and output shaft should be parallel and yokes should be in phase. A very detailed Elaborate explanation is in order like Spicer and Dana have offered. I don’t think you can answer that question within the space of these comments.

Youre not getting differential oil to that bearing thats raised in the air point under the bronco

So did it work?

Im installing a 4” lift on my 91 bronco. For rear using add a leaf and 2” block. I decided im not gonna use the block. Would i still need this even tho im going to run bronco graveyards oem rear spring angle block

why do you need to remove the centering bolt? all you have to do is losen it and spin the shim around

My pinion angle brought me here.

You can measure pinion and working pinion angles off of the bolt heads on the pinion on the rear of it as well. Do you have a double cardan?

You should get those leaf perches rewelded, so you can get proper pinion angle, that style driveshaft coming off the yolk on the axle should be pointing straight at the transfer case with it set to 0° or 1° difference.

Great video! Another common thing is the driveshaft itself is not on the correct spline, causing the universal joints on each end to be “out of step” with each other. With how old all these trucks are I’m sure at some point the driveshaft was incorrectly removed and taking apart

any way an at home mechanic can find the correct orientation without bringing it to a driveline shop?

It's definitely pinion angle AND/OR current orientation.

How about try supporting the vehicle jackstands

I have you a measurement. 90 f150 w/6inch suspension lift. Drive shaft degree is 16 degrees pinion with Drive shaft removed is 5 degrees. I have 35x12.50x15.. what degrees should I be

Wow I was worried about mine and I’m running a CV. Mine is way closer to zero than that. I think I’ll wait until all the weights back on it and drive it for a while but I was considering shims also.

Drive shaft way too short as slip spline will start to wobble. Must be lengthened. Double cardan joint by transmission is fine and proper angled shims should do the trick.

Can pinion angle vibration be intermittent at highway speed?

Great video thank you

Omg. Just what I been looking for months. I have a 2003 Ford F-150 put a 5inch lift with 35s, you think I need those shims? Where can I get them?

So now you have 16 degrees at the pinion, but do you have 16 degrees at the transmission? If your front and rear U-joints are too far apart, say pinion is at 16 and transmission is at 2, you will get binding and vibration.

Your pinion angle to drive line changes when you change 1 the other changes. You need to know look at the drive line angle. I bet total it change 6-7 degrees.

Hmmm. The important thing is that your pinion angle matches your transmission output angle. If your trans shaft is pointing down at 3 degrees your pinion should point up 3 degrees. (Measured with the weight on all 4 wheels.)

your installation explanation was wrong. ..you could have done another video, edit to remove your mistake ...this is called messing up .. and also no comments on vibration after installation

Jon, Cool to see you back again. It’s always nice when you test the function of the Bronco to include the results of the changes you’ve made prior to releasing an update. I’m left wondering if the wedges eliminated your driveline vibrations?? When I drug my ‘73 bronco from a junkyard, it had a 5 1/2” Wild Horses lift and the rear u-joint was broken off at the diff. I replaced the u-joint and quickly noticed an abnormal binding, did research, called Wild Horses & discovered that the POwner failed to install any wedge shins. I added the 6° wedges and this made a huge difference, but I still have a bit of vibration at 55mph. Perhaps the comment above by Yablo69 referencing a video about unmatched Tcase/driveshaft angle-vs-driveshaft/diff angle is the answer. It gets more complicated, however, since there’s a double cardan joint at the tcase side of driveshaft. Also, How ‘bout the relocation of your fuel pump away from the exhaust on the last vid...did that work to remedy the problem w/ the same pump? Thanks, HYoung

So what’s the update how’s it look and feel now?

Just make sure the pinion flange is the same angle as the flange on your transmission for your transfer case

Question Does it matter if the yokes on opposite ends are lined up? I was told it helps with vibration🤷🏻‍♂️

Am I the only one that realizes you did this wrong? You had the shim wedge correct the 1st time. To lower the pinion the large end goes toward the front. But you also dont know what correct shim to install because you didn't find the angle of the output on the transfer case

I just watched the vid bc I am about to do a lowered 68 Camaro. Your vid never said if the vibration went away. Also couldnt help notice the drive shaft appears to be installed backwards. Every driveline I have ever seen has the narrow slip joint away from the diff. Perhaps this may cause vibes especially if those splines are worn.

Shouldn’t it be the same angle and pinion angle as the flange on the transmission both of those should be the same angle to get rid of vibration

that driveline is way to short lol that could of caused vibration also.
