I dont want to use too large of a bit. There needs to be some metal for the stud splines to dig into; right? So what size should I use to drill out the new stud holes on my hubs?

Thanks!

9/16 is too large, I used 17/32 and it was too small. I ended up drilling the 17/32 holes, then wobbling the hub around a little to hog out a little more material, and was able to pull the studs in with an impact driver. Take the time to harvest extra lug nuts, and after using one to drive in a stud, throw it away. Otherwise you will end up stripping out the threads and starting over. Lug nuts are cheap at the junkyard.

 

 

If you can find one, I suppose 33/64 is the right size. It probably corresponds to some metric size that is equally expensive and hard to find.

14 mm
