Adding Or Removing Shims To Correct Driveline Angles

The correct driveline angle is very important for the longevity of your rotating components. In this video we show how to remove or add shims on the leaf springs to correct driveshaft angles that may have changed due to lift kits or other modifications. We also explore a few of my past mistakes...

I did mine different, I cut off the leaf spring perches grind off the old welds and placed the new perches on the axle loosely and pushed the pinion up to my desired position and then welded the new perches to the axle tubes

Very good point to C-Clamp leafs before disassemble the section!!
The cost to redo U-Bolts is cheap insurance. I get them made locally about $40.00 for the entire axle, all hardware included. Takes the shop about 15 minutes to get them done!
My local shop also has the shim pieces in 1 degree increments, about $14-17 each.
I dealt with rough country on the 3" lift kits, and am Not returning to them for anything!!! Good grief was it dissappointing!

Just the video I was looking for. Thanks!

Haha 1:21 dog is like whats down below boss?

[jiml]

What was the change after you removed the shims? Did that fix the problem or did it get woese?

G'day
I've got an old orinal hilux
Any way
Rebuild bottom end
Doing timing chain etc
The number 4
Con rod has sideways movement
If l shim it with brass
I'm hoping there's no more noise in engine
Feel free to give me advice

you want equalize the angles if under 10 degrees but have rear diff 2 or 3 degrees below to account for axle wrap under load.

[petergosinski]

I did a throttle body spacer and 4.0 throttle body. Just got my injectors and wires. Must have been too much for the ax5 because she let loose. Im ordinary the rebuild kit though. You ever do a manual transmission

[trevorthomas]

You can also do a transfer case drop, decreasing the angle.

Does anyone know if you change your gear ratio on your truck should you change install a torque converter with a different stall speed or does it affect your torque converter at all

[garygibby]

Good ya warned about not reusing u bolts I’ve run em before too never an issue so far haha hate to see one bust tho and watch the diff fly around and ruin stuff

[tomc]

Stupid question on jeeps, but why don't they put the axles under the leaf's?

[ajmontgomery]

What size lift you have? Got a 3.5" and going thru the same thing

[clayton]

On a ujoint on each end drive shaft, , the pinion and tail shaft need to b parallel to each other, , the way I do it, , I take a digital angle finder on my phone app, , I put it to the pinion and zero it out, , then put it to tail shaft, , gives me what degree shim to use, , then do it visey versy and same number, , this would b with moderate lift, , before you have to turn pinion and go with cv on driveshaft, ,

[bluedog]

So the shim between the axle and the spring is lowering the vehicle.

Hello,
I saw your video really helpful thanks.
I have a problem with my 04 ram is lifted and every I drive into a bump I hear grinding on the front drive shaft or when the truck is loaded what would you recommend on my issue?
Thank you again

[doubleoseven]

I really think those shims need to stay there. By taking them off you increased the slope from yoke to yoke. I recommend you get yourself a magnetic angle gauge and get your pinion slope and driveshaft slope... you probably need a thicker shim to compensate your slopes.

[pratrian]

It’s all about the angle of the dangle.

[michaeldose]

Never get under a vehicle supported by a bumper jack.

Like you’re channel but you should NEVER EVER refer to a JEEP as a
