drive line vibration after 3" lift install

So i checked the u-bolts and they were fine 75#. added CB drop, and already have the 1" diff drop installed. still vibrating but much better now. looks like i need to shim the rear. anyone know were i can order them? The rear was lifted 2" so i think i will try the 2deg shim, and thanks for the advice.

 

You can get 3* shims from Toytec

 

the last Haynes manual i owned, i used as a jackpad on my floor jack to protect the cars...it worked GREAT!! lasted for years. in the end, i got a few more uses from it by wrapping it in duct tape. it was a GREAT manual.

"install in reverse"..hahah.

 

Have struggled with this issue for 6 months. Lowered the drive shaft...raised the drive shaft...nothing worked...until.....noticed that the mechanic put the rear suspension blocks in backwards (3 degree blocks)! Turned them around and ZERO vibration....Praise the Lord!

 

Glad that you have the vibration sorted out.
Are you saying that you had 3* shims and that they were installed backwards? Thin end facing towards the rear?

I also have a slight shudder/vibe right at roll out after installing OME lift & Dakars. I've installed a CB drop, but haven't installed rear axle shims yet. Yet...

 

Yes. The 3* shims came with the kit and were installed backwards. If you look at them real quick you can't tell that there is a difference, but when you measure the ends you see it. Turned them around and BOOM...No vibration on acceleration or braking! You probably won't need the CB drop with the 3* shims, but try it and see.

 

How much lift is your leaf pack providing?

Thanks for your post too.

 

I installed the 3* shims and my shudder/vibe at roll out is much better. I kept the CB drop in place, and installed the shim with the thin end facing forward.


I still have to measure my driveline angles, but the transmission shift lever doesn't shake and the truck doesn't shudder on roll out anymore.

Now if I can figure out why my U bolts nuts are flush with the threads...

 

I just installed the same lift on my 2016 Tacoma. Im getting alot of Vibration as if Im riding on boggers when I start to slow down. Did you figure out the problem?
