u-joints

i have an 86 cj7(258)two month ago i intalled my four inch suspention lift,now since then i have lost 2 rear u joints(one of them today)it has the shims on the springs.but i was thinkin about lowering the transfer case but with the 1 inch body lift on there it already has my clutch adjustment leaning down.wouldnt lowering the tranfer case really put a bind on the clutch linkage.any help would be very helpful.thanks in advance.doughboy

Re: u-joints

the u-bolts on stock jeeps are too small, they loosen up..check them and tighten them as tight as you dare.. i think that will fix your u-joint problem. if you still want to lower the x-fer case a bit, then drill 2 new holes in the body an inch lower and a half inch closer the the tranny(I'm talking about where the linkage mounts to the body) this will keep the linkage together better

Re: u-joints

The real solution is not to lower the xfercase. What you need is a CV-joint rear driveshaft. It cured my u-joint problems after the lift.
Lowering the xfercase just loses you ground clearance. If you go the CV route, shim the rear so that the pinion points at the second
u-joint in the CV-joint.

Re: u-joints

You shouldn't use a shim that big, cut the old perches off and weld new ones on. Take the measurements now to see how far you have to move it.

Re: u-joints

what u joint is breaking? the one near the axle.. ? then you probably have axle wrap.. kicking up the pinion on the rear axle.. when you accelerate hard.. binding the joint and breaking it.. is this when they break? if that is the case you could use some kind of a hard link.. and there are many ways to sovle this problem..
