it snowed the other day, and now whenever I go to spin the wheels, or are moving in first and give it gas to upshift to second (AX-4 spd) the rearend will violently slam off the ground. Almost like axle hop when you dump the clutch in a fwd car. Ive got nothing for shock absorbers in the rear, and don't plan on fixing them till spring, when I do all the body work. Would the shock absorbers be the problem or would it be something else. Its a stock D35 2wd '89'er MJ.

yes, I broke the shocks in the rear and it causes the ass end to track weird and when I hit bumps the springs "unload" a little bit

both have exploded, both are OEM shocks from Factory in May of '89 And Im in the rust belt. (Ontario) It makes for some interesting body roll, weird rear tracking and the rear end slam when shifting in higher rpms. my bushings are ok and the leaves are fine too.

just a cheepo set of shocks would do wonders then...............


shocks should have little effect on rear end tracking on a leaf spring suspension....

but spring oscillation......... yep... for sure.

i would throw a set of cheapo crappy tire specials in it til spring. iirc the mj's don't have bar pins on the top so no worries about rusted bolts making for an easy swap. no telling what the arse end is gonna do in a sticky situation on the road.
