Not to threadjack, buy I just had the same problem the other day. My "screw" made thump thump thump noise as I was driving. And my tires are only a few months old.
Fortunately the shop fixed it. I hope it stays fixed too.
Ha Ha very funny guys . Im good. got to the shop,pulled up to the rear door where a guy was on a smoke break. I pulled it out with him as a witness. turns out it was only about
a 3/8 of an inch screw. sprayed some simple green on it to see if there was any bubbling.
Im good to go
now what do I do with the rest of this beautiful day off
