2005 500LE stud size and replacement

[data89]

All my studs on the wheels have the beginning 3/8 inch worn by rust as have each lugnut, so their integrity is very poor. Especially since not much of the stud extends beyond the wheel to begin with, and several of the lug nuts have no purchase at all, so they won't even stay on. My question first off is, "what is the thread size of these studs, and how difficult are they to punch out and replace"? I see new ones are available. I would hate to take a hammer to the old stud to knock it out only to break the wheel hub.

Does anyone have any knowledge of this situation?

What...nobody knows the the stud thread size???

I haven't even gotten a response from DirtCheapParts which is usually pretty reliable.

10mm X 1.25 is the thread. Remove the hub and heat up the area with a torch and you should be able to pop them out.

Thanks,

studs and nuts have been received at my friends and I'm waiting for him to bring with him when he comes here to Panama.

Okay, heated the studs and got them knocked out. Problem now is the new studs are so tight I've already stripped one of the stud nuts. So, now I have to take off the axle nut and take the whole disc and brake off. Question is, is the axle nut left hand thread or right hand thread? clockwise or counterclockwise? And heat hasn't worked on that so far. I may have to split it to get it off, but would be good to know which way to try and remove it

[mikeexplorer]

normal thread, lefty-loosie, impact wrench is the best way to remove it.

Thanks, got the axel nut and hub off with LP torch and breaker bar with 4 foot extension. Now, I can't get the bolts out of the brake disc. Torx head, which is good, I have that, but so far heat won't loosen them.

Got her done. I filed the edges of the disc bolts so I could get a vice grip on them, then a little heat and they came out slick. Then I was able to pound the studs in. Man, they are tight. Got it all back together and ready to ride.

By the way, the axle nut is a 30mm or 1 3/16.

Thanks for everyone's help.
