I have a 93 wrangler.. all stock but a 4" confer shackels.. I am running 33 12.5 tires.
I always burn out the rear u joint at the axle the drive shaft is stock. no bends or dents or deformation.. any help out there????
still have the slip yoke also.. a u joint lasts about 2 weeks before its gone or sooner.. like a trip to the con from antelope cali.. and back after going in to the slabs
help??????

Shim the axle to make up for the lift...you want to match the ujoint angles of the DS at the pinion end and the tcase end.

You can get shims at any 4wd shop

the angle is almost straight with it loaded down.. with the gear.. I was thinking about a spring over I will check out the wedges and see .. thanks

how worn is your yoke? i would guess it is bad. how tight is the ujoint after you put it in?

the yoke was replaced with one that was tight.. it broke about a month ago.. all joints were tight.. and I used spicer u-joints.. they last as long as the others.. ...
anyone have a slip yoke eleminator ??? I need one bad...lol:confused:
also looking for the cv joint driveline also..

Sounds to me like your pinion angle is wrong, or your pinion is moving a lot, which means you've got wrap.

hmm.. might have that also.. my springs are flat no bow in them.. all stock also...

Bad pinion angle... 'Nuff said

Unless you are running a CV, the pinion angle should not be straight. Unless of course the transfer case ouput has been lowered until it points directly at the pinion. I would certainly doubt that. The angle of the ujoints should be the same at both ends. ie. if it has a 8 degree angle out of the transfercase, the pinion unjoint should also have an 8 degree angle.
