How do you keep the hub cap lugs from stripping on 2007 silverado?

Answer 1

Dont know about 2007s, but my 2003 has had this problem since new. My dealer showed me a TSB (Tech Service Bulletin) that said the plastic nuts should have a small line if black RTV across the threads in one place which "glues" them onto the steel lugnut external threads. An independent brake mechanic once told me that he knew about this, and it was right, they should be RTVd on every time they are reinstalled, however he said that the red RTV is better because it was more temperature resistant than the black. BTW, Chevy replaced four of mine lost back when it was under warranty. Since then I have paid for replacing a couple more (not from Chevy parts Department though.) It is a really poor design.
