I installed a set of 1.5" lift blocks in the rear, and when I went for a test drive I noticed the rear seemed to hop and bounce more that it did before, especially when I shift gears. I have checked the leaf spring and shackle bushings and they seem tight and I also checked the transmission mount and it seems fine as well, the only other thing I can think of is the shocks are worn out, or maybe it's the lift blocks causing this but I wouldn't think a 1.5" block would make much difference . Is anyone running lift blocks in the rear and having this issue?

 

All the 2nd gen full sized trucks have blocks in the back..... May want to re-torque ubolts.....

 

Yes I am aware of that but I thought maybe the Dakota springs were to soft to handle a block and it's causing axle wrap, but like I said before its only a 1.5" which shouldn't make much of a difference, I usually retorque u bolts after 100 miles or so but I will go ahead and check these.

 

You wouldn't think that that small of a block would have much effect..... any other changes to the rear suspension?

 

Update, the throwout bearing went bad so I put a new clutch kit and replaced the transmission mount and it's solid now.
