Bilstein lvl kit at 2" with 1" rear block vibration issue?!?

Hi all,

I have a 2017 Toyota Tacoma TRD sport.

I have read through several articles about drive train vibrations etc. but have yet to find a cut and dry answer. I recently had Toyota dealership install a Bilstein leveling kit, 5100 adjustable struts and shocks, diff drop kit with a 1" rear block. The front is set to 2". I noticed vibrations right away as I had already put 10k km on the truck stock. I took it back in and they said they could install different spaces in the back that are shimmed. They have now done that and the vibration is still there. I noticed when I put it in 4wd it pretty much completely disappears. Now I am taking the truck back in to get updated leafs in the back that "are going to get rid of the vibration" (even though I don't see how but its free updated leafs....). Anyone else had this issue and have a fix?

 

Welcome to TW. Your issue sounds like a needle bearing issue. Check out this thread: https://www.tacomaworld.com/threads/front-diff-vibes-ecgs-bushing-fix.464941/

 

Roger dodger, thanks Jonny. That is what I had sort of narrowed it down to after a bunch of reading just needed to confirm. Is it something that just happens to the odd 3rd Gen Tacoma or they all have some issues? The truck was perfectly smooth before so the lift maybe just made the existing problem more prominent?

Now to try and steer the dealership techs to this issue and get it fixed....
