I have a buddy who just got new wheels. He was running adapters in the rear only due to clearance of the rear links. He has one set (2) that are brand new, and the others he took off the rear. He told me today that He broke a stud on the jeep itself removing an adapter, and thinks it was cross threaded. I intend to inspect the two used ones, but not sure if anything I should be looking for other than stretched threads, and possibly damage to the rear aluminum where the studs for the adapter are seated. Will there be any visible or measurable issues at the stud mounting locations on the adapters if they were over torqued? Thanks for any thoughts.
