Installed 5100, OME 887 & 1.5" AAL + left overload spring in = Vibration

I have a 2wd sport.

I had some vibration 25-15 mph prior to the lift. I'm now experiencing more vibration and also during take off and at low speeds in parking lot.

Will a carrier bearing spacer kit like OME offers help?

Without measuring driveshaft pinion angle. Is 2 or 3 degree axle shim common to use with AAL?

Truck sits little higher in back (1"). Will axle shim add height? If so, might remove the overload spring (1/2") while I Install a axle shim.

Ride quality is great tho. Just need reduce the vibration. It's not horrible but can def be better.

 

Axle shim will not add height and yes its common to need shims if lifting the rear.

Measure pinion angle to be sure but my guess would be to start with a 2 degree.

Be sure to recheck u joint bolts for proper torque especially if you had vibrations before installing the lift.

 

Thanks! but wouldn't the thickness of the shim add height? I'm sure be very little right?

2 degrees makes sense. I see websites say 1 degree for every inch of lift.

What do you think about the carrier bearing spacer?

 

I'd replace one thing at a time and start there.

Technically the shim will add height but it will tilt the axle to be more in line with the drive shaft. The added height would be negligible.

Not my installation but a pic grabbed from TW about shim installation.



My rear leaf setup with 3 leaf AAL and overload installed, no vibrations.


I also have a DCLB so I'm not sure if the longer driveline might have something to do with not needing shims.

 

Carrier bearing spacer may be the easiest to install before moving to the shims... All Tacomas are different, but I have 885/5100 and full Dakar pack and no vibration with the spacer, so far.....

 

one or the other, whichever is cheaper and easier.

Fat Bob's has the carrier bearing kit for $14.00 with free shipping.

Shims can be from very cheap to pretty pricey depending on material.

 

I'll check u bolt torque, then move on to carrier bearing spacer, then 2 degree shims. Thanks guys

 

Heres a quick reference for maintenance including torque specs for almost everything on the suspension

Did your 3 leaf AAL settle down some after a while. I feel like I got little more than 2" with overload in. I only put 50 miles so far since I installed the rear .

 

Not too much in two years, maybe a 1/4 inch or so but I have a tool box and run with rear passengers quite a bit.

I dont want it level, especially loaded down otherwise it will look like its dragging ass, especially when accelerating.

I wanted factory rake at least

 

Nice! Yeah I have to agree with you on not wanting it to be perfectly level. I measured mine. I have exactly 1" difference front to back. I believe its like 37.25" up front and 38.25" in the rear (floor to fender).

I get my SCS black ray 10s today and ill order 285/70 17 nitto ridge tires soon.

You get the extended 5100s or regular length?
