Question about vibration

I just installed a 3" toyTech lift on 2010 V6 Dbl Cab, AAL and new front coils. I have a small vibration when I accelerate between 5 and 10 mph. I havent aligned the truck yet but it doesnt seem like that would be it? I also installed the 1" drop on the diff. Any ideas?

 

A couple things:

welcome to tw (we like pics, show us the lift)

lots of topics on this in the suspension forums and 2nd gen section. Lots of people have had good luck with the 3 degree axle shims. It takes some experementing as well

 

love pics.....

 

try a smaller diff drop using the same bolts and stacking washers. My magic drop height was a bit less then .5" more caused a vib at 5-10 mph, less caused vibes 0-5.

 

Thanks for the information, I'll post a few pics tomorrow.

 

try this.......
