Issues with wheel studs

gomer_110 · 12-01-2022, 07:59 PM

Some years back I definitely got a bad batch of wheel studs from Z1. The knurling wasn't even close to being right though in my so I was able to catch it during the initial install of the studs.

Since then, if I ever have to replace a stud, I always confirm dimensions of the new stud(s) just to make sure.

Get new studs. Replace them all with ARP studs. With the stud spinning, the bore maybe to large now for the knurling to bite into. If that is the case. You will have to put a tack weld on the back.

I've had an issue recently with ARP studs too.. make sure you carefully/hand thread on a lugnut the whole way before going to town with the impact. The threads weren't noticeably bad, but something was off and I've locked up and spun a few in my last batch.

I swear by the ARPs for how often I take my wheels off and on.. but definitely will be checking each of them by fully threading a lug before install in the future.

I always start my lug nuts by hand for the 5 to 10 turns. Then use an air ratchet to take them the rest of the way. Then torque them down. My air ratchet is 100 in lbs of torque. It will stop when it hits a bad spot.
