So i have to change the ujoints in the wheel joints in the front end. Any tips? 89 Cherokee Pioneer 4.0 5spd.

 

Apply PB Blaster to the bolts for the unit bearing hub and u-joint caps for a few days before getting started.

 

If you have the original 12 point hub bolts and they are rusted so the socket slips, the easiest way to take them off is if you have an welder ( mig ) is to take an old socket, hammer it on and weld the socket to the bolt, then esay to remove.
5 easy minutes to remove bolts instead of hours of frustration.

 

I've been soaking them with lube and will have access to a welder and a torch if need be.
