I've been trying to search for some help, but unable to. So here goes, a lug nut was stuck on my front pass. tire. Its stripped out now, how do you replace that lug nut stud?

As always thanks for the help!!

 

Any idea how much clearance there is behind the studs? If there is room, drive the old one out with a punch, put a dab of grease on the new one, slide it into place, then use a couple extra lug nuts as a spacer while you tighten one down to pull the stud in. When you see grease oozing out around the head you know you have it in all the way.

 

I wouldn't use ANY method that involves hammering, as you will be putting damaging loads on the wheel bearings if you do. Some kind of "press" action, only.

You can use lug nuts and spacers to pull the new one back in.

Thanks for the tips.

 

grind it off flush, then center punch it and drill it out. use a drill small enough to leave material so you dont hit the hub. then using a punch it will almost fall out. no heavy hitting.
if you can get the new stud in with the hub on, tap it so it just starts. use washers to protect the hub and use a lug nut to pull the stud into place. youll need a few washers. if you can get at it it takes less than a half hour to complete. or one beer. lol
cheers

 

Do you think a few raps from a hammer is going to be any harder on the hub bearings than the forces exerted from typical driving? I would think that, even though its not in a "normal" direction that any damage sustained from driving the broken stud out would be negligible at best. Maybe I'm wrong though, it has been rumored to happen occasionally

 

you can "bang" them out with a center punch and a 6 (not 16) oz ball peen hammer AFTER you line up the hole in the caliper plate with the stud. doesn't take that much force. If you don't line up the hole properly, the stud head falls into the dust shield and you then get to take apart the brake. Use the Big hole, there are 2.

Yeah I know it ain't a press, BUT it is really hard to get the press to function on the side of the 405 freeway near the LA airport. That was 87,000 ago, 1 lug nut recall, about 8 tire rotations, 1 brake job, and a new set of tires later.

note to self: check calibration on 3/4 drive torque wrench again

 

It's really easy on the front of duallys, lol. Pop the spacer off, and bang away.

Had to replace them all in a walmart parking lot in the middle of nowhere once, broke all but 1 of the studs on the freeway. Borrow a jack from the service department, a bang or two with a mini-sledge borrowed from wally-world and they were out. 40K miles later and the wheel bearings are still good, 170K miles total.

 

If there is room on the stud, I would put two more lug nuts on, tighten them together so you can unscrew the stud out of the hub assembly. I think it would be better for the hub assembly, less wear on the hub assembly itself.

 

The studs don't screw in and out.

They're pressed in and out, and have tiny "splines" that they fit to prevent them from rotating in the hub flange.

Though the ones for our trucks are longer, the photo below will give you an idea of how this works.

DOH, I was thinking about the 4 studs that connect the hub assembly to the axial, my bad, thanks for catching that.

 

Ahh, yes! You are correct about THOSE studs! They are threaded on both ends.

Here's an example of a tool that could press out the broken stud if modified slightly:

 

Well sounds like its a one beer job, maybe two for me. I really appreciate all this good information. Thanks to all of you!!
