I had my mechanic install a set of the heavy duty springs from Quadratic as well as a set of shocks in the back.
I also installed a TNT cross member with no t-case drop.
My rig sits a bit higher than it use to as my old springs were to the point of frowning from all the sag. After the install, I seem to get an occasional thunk noise when I take off from stop. And at high way speeds I seem to have a little more vibes in the rear than I use to.
Some of it I suspect is from the stiffer ride for the vibes, but the thunk has got me baffled. The only thing I can think of is that I have increased my drive angles and until my new springs settle in, I will have to much angle.
I grabbed my rear drive shaft and gave it a twist, but it felt solid. Could my u-joints be going and the increased angles are making it more noticible?
I have a pretty much stock '96 with 30 x 9.5 BFG TK/KO's that I have been running for the last 6 years. AX15 5 speed tranny and 8.25 Chry rear end. 81,000 miles on the beastie.
