Hey guys I was wondering if anyone else has had a vibration at low speeds after installing a toy tec add a leaf 1.5" to 2" lift. Also installed the Old Man Emu rear driveshaft spacer (FK29).
I use to have a 1.5" block in the rear with no vibration, so I figured it would be straight forward switching to a AAL. I have 5100 all the way around, original install also included a front diff drop kit.
Could there be a different angle now creating a vibration, or should I go over the truck loosen off the leaf springs and torque down again??

Sounds like the drivers side needle bearing. Does it go away in 4wd?
 
It will be there out of 4wd but if you drive around in 4wd do you continue to feel it at 30-40mph while in 4wd? When you turn 4wd off you’ll feel it again.
 
I had the needle bearing changed out to a bushing when I had the front lift done.
Is it possible that I need shims in the rear.
 
My 2018 sport with 33's and a leveling lift has a minor vibration it is noticeable for a few seconds goes away gor a few seconds and repeats again and again any ideas

I use to have 1” spacer adapters on my last Tacoma. Looked awesome but wobbled going 40-60. I learned the hard way but some one told me u need spacers that are hubcentric. I haven’t tried them but every one has pointed me towards the hub centric only.

Thanks for the reply, I ended up having to put a couple of 2.5° shims under the leaf springs. Took care of the problem, rides like new again.
