Need Some Info On Disassmbaly The Wheel Hub Wont Come Apart So I Can Get To The U-joint

 

Loosen the 4 bolts holding the hub on. Leave the bolts in a few threads, put the socket on one and an extention, have someone there to help, start the truck and turn the wheel so the extention hits the axletube and is pushing on it. Turn the wheel with a little force and it should pop the hub right out.

 

While you are in there, I would recomend putting in greasable ball joints.
Just getting the axel out is enough of a job, one more step and you will have one less thing to worry about.
