May have a broken stud

I was trying to take my wheels off to clean them for Carisle. I could not get one of the back wheels off because one of the studs kept turning. I can tell that the lug is loose but I can get it out. How do I get the lug off with out damaging the mag? I have drum brakes.

broken stud

Drimmel the Lug Nut....Wheel studs typically have a straight splined knurl and are pressed into the wheel/axle hub from the back side....I suspect that the splined fit has twisted freein the hub

Over size studs are avaiilable for repair

If you can get at it... I know, a very big if, there is a tool called a nut buster that should be able to split the nut for you. Once you get the nut off the stud the rest is not too bad.

Any good parts house that carries tools should have one, including places like Jegs or Summit.

Otherwise I'm inclined to agree with skeew, a Dremel is probably your best shot.

Good luck... GUSTO

the lugs are reset so I wouldn't be able to use that tool. Is drilling in to the lug the only way to get it off? That seems to be taking a real big chance of hurting the mag.

Were you using a lug wrench? If so, try going to a local shop and have them use an impact gun - perhaps between the torque and speed it might work.

If the lug galled the stud, and caused the stud to spin in the axle flange, well, that is definitely being somewhere between a rock and a hard place.

Your only choice, IMO, is go to a place that has air grinders and such that that can take few hours and get it off, hopefully, without damaging your wheel.

If i had to brute force this, I would use a die grinder with a cutoff wheel to cut the head off the lug such that the bolt cavity was exposed, then use same die grinder and notch the side of the lug in two places 180 degrees apart, fairly deeply, then try to split the lug with a cold chisel.

I would not expect it to be a $50 fix.

PS: anti seize lube on the threads would be a good suggestion for the future, adjust torque accordingly to account for the lube.

You might try drilling a hole straight into the lug nut all the way through. Then split the nut with a chisel. All straight shot work.

Also, the impact wrench is a good idea. Take the four good lug nuts off, then pull toward you on the wheel opposite the bad lug while you try to zip the nut off with the impact.
