I'm installing my RC 2.5" lift on my 97 4wd Jimmy and need to remove my axle nut but don't have the wheels on it. I was wondering how to lock up the front axle enough to remove the nut. I have tried braking while trying to remove the nut, but I just spin the rotor. I was hoping you guys could help me out. I know this is a stupid question, but thanks in advanced.

 

Crow bar and a rag. Position the crow bar with the rag wrapped around it in the appropriate areas between a couple of the studs on the rotor. A helper comes in very handy to hold the crow bar while you crank on the axle nut. You could also use some vacuum tubing/PVC piping of such size to fit just a little loose on the studs.

If you mess up a stud, they are cheap and easy to replace.
