Shimmy after TSB

Have any or all of you that had the rear leaf tsb completed noticed any driveline shimmy/vibration afterwards?

 

Yeah, around 10 mph. Then it goes away.

 

well for what it's worth... I have it now....no tsb yet!!

 

Maybe get your tires re-balanced?? Its possible they mixed them up when they took them off and ones that were on the rear are now on the front and are out of balance. I had that problem after a rotation, but no vibes from the TSB.

 

^X2 maybe check the torque on the U bolts and hangers jus for good measure

 

and if your wheels are on tight too....u never know its the dealership were talkin bout

 

I had a nasty driveline vibe from 20-30mph after the TSB. It wasn't a shimmy, it was a clear higher frequency vibe that was rattled everything in the cab when it happened. Put 300lbs in the back and it would go away. I had them pull the old springs back in. I still have it, but I only notice it on decel and it is tolerable. I still have torque dependent drivline vibes. Still havn't tracked down the source.

 

No problems at all for me after the TSB.

 

ive got the same vibration at 10 mph. no tsb but do have a 3" toytec lift

 

I got an 06 AC 4x4,and after the rear leaf TSB done i got the same shimmy at about 10 mph.I got mine done in june,and it has not gone away.I guess i'm just gonna live with it like so many other people.The truck is great,but i don't like the shimmy.And i did'nt put on my 5100's until after the TSB was done.So i know it had nothing to do with the shocks.I have them set at .85. And no issues at all with that.Would like to go 1.75 setting,but i will wait till funds permit.I highly recommend the these shocks for a mild lift.They handle great on and off rd.

 

Tsb and 5100s @ .85
no shimmys or other problems

 

Here's my 2 cents.
If a dealer does the TSB on your truck they aren't doing you a favor.
They are doing what Toyota recommended.

If it shimmies, vibrates, etc, due to that work being done then Toyota is responsible to correct any problems. For free.
You don't have to just live with the problem.

 

Check the TSB for a shimmy...it consists of replacing the rear trans mount with a stiffer one. I think it applies to your truck, the stiffer suspension upgrade could have brought up another problem you got.

 

I installed a Toytec kit with the Alcan AAL on my 06 Tacoma a few years ago and ended up with a vibration from 0-15mph. The only fix I think that the guys on TN came to back then was switching to a one piece rear driveshaft.

 

this is what I have heard too. I will getting one next year.
