Shimming aint helping!

Installed 4 inch lift this past weekend, and low and behold, after who knows how many different combinations of shims under the carrier bearing, I cant get even close to getting my vibration gone. Installed tapered 5 inch block in rear, and springs in front. I know everyone says to use flat block with 2 piece driveshaft, but its what was available to me. Am I missing something? The more I shim, the more the vibration changes "feel". Once I had an inch of shim in, the vibrations felt like more of a "hum" through the steering wheel. I dont know what else to try.

I installed a 4" lift on mine and didnt install any shims in mine. Definatley check your carrier brg and you might check your ujoints, if there is any rust aroud them they may be tight or binding.

I agree with these guys. How much taper is in the blocks? When using tapered blocks you should be using shims with a slight taper as well.

Shoot a PM to DC Special with your lift info and he should be able to figure it out. Or if you PM me or call me tomorrow afternoon I should be able to dig it up
