I stripped 2 wheel studs this past weekend. both had the same failure mode, a chunk of the stud broke off inside the lug nut and trashed the thread, making it cross thread on removal. 1 broke the stud at the wheel, the other came off, but trashed the stud the whole way up.

I think I'm going to replace my torque wrench. It has been through a lot and is kinda old. Other than that... any suggestions as to what is going on?

I have never had problems with stripping lugs before. I've been doing track days for 6 years and have never cross threaded a stud or a wheel bolt (BMW) because I'm really careful with them. maybe my torque wrench is getting ass, I don't know.

*sigh*

$400 labor and $65 in parts for new ARP wheel studs installed at all 4 corners.

 

This just happened to me also. I have a broken stud and one that is stripped. We also have another member that just had to replace two of his. .

I was planning on doing this myself. Why is it only 65.00 for parts? Aren't you going to replace the wheel bearings?

 

Welcome to the S2000. I recommend a bit of anti-seize on the lugs from now on.

 

Hm, should I replace the wheel bearings? Car only has 10K on it. I'm going to extended lugs and open lug nuts just in case I go big brakes up front.

I didn't think the wheel bearing had to come out, I thought it was just the hub that came off?

 

What's interesting is that this never happened with my MY2000, but 2 in one weekend with my 04! guess I really need to replace that torque wrench.

 

you have to press the hub out to get the studs in. doing so, destroys the bearing and you'll have to replace them.

 

ah crap that sucks, the bearings are $60 each! is that true front and rear?

 

*sigh* just ordered the wheel bearings, $60 each x 4

I hate cars.

 

If you change wheels with any frequency, always maintain antiseize on the studs. All you need is a little dab of Permatex antiseize on each stud maybe once every other year.

I'm glad to see I'm not the only one advocating a little anti-sieze on the studs.

I had the start of galling on the wheel studs on my MY 2000 car, so I started using a small dab of anti-sieze and that prevented any additional metal transfer. I also find it very useful on the bolts around the braking system. I just serviced the brakes on a MY 2004 car with 5k miles and most of the fasteners that I removed had the beginning of corrosion on them - a whitish crust that make unscrewing a couple of them difficult.
