question on vibration...

i have a 2011 tacoma with the readylift sst kit the 2.75 in the front and the 2" block in the rear... I also installed some bfg all terain 265x70xr17 tires on the stock wheels when I take off from a dead stop i feel a slight vibration and then it goes away it does it from about 2 to 5 mph... any ideas what i can check out or if something needs to get changed out thanks in advance...

 

you need 2 degree axle shims and put them in with the fat part forward so it shims your rear axle down. when you have a u joint axle, you want the angle at your tranny and the angle at your rear diff to be opposite to cancel eachother out. also turn your blocks around or get rid of them for AAL's but they are cut with a small inclination to shim your axle also. pickin up what im puttin down?

 

so i just install 2 degree shims with the thick part facing foward and that should take care of it..

 

should take care of it, also turn the blocks around if you plan to keep them.

 

Shouldn't the fat part of the shim be rearward, to reduce the angle caused by the lift?
I've not done it, so I really don't know... that's just what makes sense in my head.

 

This ^^^

Fat end to the rear

 

I was under the truck and the block is cut like a shim on one side but the fat part is facing rear should I turn them around and try it out????;
