spare tire carrier problem

[tcalz06]

I bought another entire unit used and it works great. Only difference I can see is that this one has the rubber insert piece where my old one was is missing some if it. This rubber piece might keep the arm from vibrating but this other one feels more solid when it latches too.

I called the company who made the latch for GM and they say only GM has the spare parts and they never heard of one failing

I just took a 3500 mile trip and it never came unlatched once.
