06 F250 SC/SB PSD with factory 20's, Track Bar Relocation Bracket, 2 inch spacer and 5 inch rear blocks. I also have bilstein 5100 shocks and dual steering stabilizers. With this set-up the truck rides horrible. I have tried to correct the bump steer but it still wonders down the road. But my main concern is with the rear end vibration which seems to occur at 45 mph. The truck just doesn't seem to ride smooth at all and likes to bounce a lot. I am getting fed up with the bouncing and are looking for some way to solve my problem. Suggestions?

 

did you adjust the rear dif pinion angle with the lift kit?

No i did not. I know my angle has to be off with the 5 inch blocks. How can I adjust this?

 

they make shims to put under the springs at the blocks..

I don't know how much adjustment you need.. a 4x4 shop should be able to tell you, and might have the shims..

do it soon, before you damage the rear U joint and have to replace that too..
