Broken wheel studs

Hey folks, just dropped in because I'm looking for some help. My mother calls me from MI and says she's managed to shear off all but one of her wheel studs. The truck is at her work and she wants to know how to fix it there. I'm in another state, so I can't see what's behind the wheel. It's a 95 4X2 w/ 3.9. I need to be able to tell her whether she can just pound out the old studs and draw the new ones through with an electric impact, or if she's going to have to have it towed to a shop to have the axle shaft pulled. Hope someone can help.

A press would be better for removing the broken studs than whacking it with a hammer. Banging out a stud with the hub still installed can damage the wheel bearings.

If its a front wheel 2wd with disc brakes, the studs can be removed from the disc rotor after pulling it from the knuckle. Front studs with 4wd and rear axles will require a removal tool to prevent hub/axle bearing damage. A C-clamp and a large wrench socket will suffice.

New studs can be drawn into place using 3-4 washers and the lug nut. Soap on the stud shank (not the threads) will help with installation.
