Well, I striped a wheel lug stud just now. Swapped out tires to the Motoclaw, torqueing to 78 lbs ft and she went. The manual calls for 88 lbs ft. I have been lubing the treads so wanted to stay away from full torque. makes me wonder if these studs are good quality material.....No problems with any of the others though.

Personally, I think they get weakened at the factory from over torquing. I had to drill out quite a few screws when I was installing accessories to get them out. Good news is, you can get replacement studs quickly.

The other good news is there is plenty of room to replace the stud without pulling the hub. Used my trusty Harbor Freight ball joint tool and it popped right out!

Did you get a new stud in there?

 

[Bill B 1]

Yep. Pulled it right in, no problems.

I just experienced a stripped wheel stud and this thread came up in a Google search. So I decided to update it. I always hand torque my lug nuts after cleaning the threads so was surprised this happened to me.

I was able to get the lug nut off after:

soaking it in penetrating oil
removing the other three lug nuts
having a helper twist the wheel to put pressure on the stud
using an impact

Once the nut was off there were no threads on it or the stud. I used a 3-pound hammer to knock the stud out the back.

I located a replacement at Advance Auto after the counter man allowed me to poke around the inventory in back. This works:

M12-1.25 Serrated Wheel Stud - 14.35mm Knurl, 42mm Length

It was a little longer but no biggie. I grabbed another lug nut there. It was for tapered wheels and I flipped it over so the flat spot was down on the washer. I put all four washers on the new stud and used the impact to pull it through. My first time doing a wheel stud.

Good find.

Here’s a tapered lug nut that works. Just put it on upside down so the flat part goes against the washer. It’s also not 17mm, its 19mm. But it’s available at any Advance Auto parts.

Almost 2500 miles and maybe 15 wheel removals? The other 15 wheel studs were all in poor shape so I changed them all. I’ve been working on cars for 40+ years and never changed wheel studs. Is it me or the KRX? Anyway all 16 are done now. Just whack ‘em with a 3-pound hammer they come right out. LOOK - the studs are made in USA!
