About three months ago, the front driver side lock servo came loose in my 99 2 door (OBS) Tahoe. The servo was riveted in and clearly lasted
10 years.So I drilled out the old rivets (didn't pay attention but I'm pretty sure they were aluminum) and popped in two new aluminum rivets. All was well for a couple of months now the servo is rattling when I slam the door. I pulled it all apart tonight and sure enough there is now slop in the new rivets.
What is the best way to fasten this thing back? Does a body shop have better rivets from the box store? Should I put it in with hardened machine screws with loc-tite? Seems like there is room for short screws. GM probably used rivets because those are fast in assembly.
Any experts have advice on how to fix this one once and for all?
