Ive put some work into my 1995 ford f-150. it has a 6 inch lift, installed by myself, so i know all the installments. heres the problem. lately when i drive my truck i will go over some bumps in the road at about 35-45 mph, then all of a sudden my whole back end starts shaking to no end. So whenever it happens i have to change speeds and swerve left and right to stop it from shaking. any ideas as to what could be wrong? i had a few options: never installed an extended driveline, (but its been that way for awhile), 6 inch BLOCKS.
