power mirror pivot
Betcha haven't seen this before.. or maybe you have! '80 power mirror; driver's side has always been loose since I bought it - the head is loose from the tower. Just haven't had time or inclination to get in the door and fix it since I'm afraid I have to pull the glass. Today, closing the door, the mirror glass dropped a little bit. Hmmmm
Pulled lightly at the glass to see what was up and found it was only held by the two push-pull arms at the back. The center pivot mount had busted:

So.. faced with I have to get in the door anyway now, is that little pivot even available anywhere or am I screwed to purchase a new or used mirror?

:-) Guess I answered my own question with a quick search. I didn't know it was called a "Trunion" and seem to be available at most Corvette places. Order placed (cost more to ship than the part!)... now to get the mirror off!

Ok.. quick bump for a second mirror question: Now that I've replaced the trunion, the glass itself is still bouncing a little during a drive. The head of the mirror is tight on the mount, the motor assembly is tight on the head. The only thing that changed when I replaced the trunion is the little rubber boots over the drive pins had torn (really, no choice there) and the pins themselves came out of the drives with the mirror. That in of itself wasn't a problem - they slid right back into the drives, I was able to snap the trunion in place on the back of the glass and I have full range of motion again - except that it vibrates more than it should. What did I miss? I could go full Bubba on it and put a few pieces of foam rubber behind the glass, but let's not try to do that... :-)
Ideas?
Thx,

If you have play in the threaded studs that go into the motor assembly...there is not much you can do but take it a part and see what you can do. If the gears that are in the motor have play...thus the studs move.....good luck on that one. IF the gear on the motor that contacts the gear that the stud(s) go into has play...it gets even better.
Keep this in mind. GOING FULL BUBBA is OK....Because sometimes you HAVE NO CHOICE...unless you want to pay a company to make you a part and your mirror repair can cost your hundreds of dollars.....or go buy used ones.
In a scenario like this....doing this stuff for a living and my time is money. I can only invest an hour in finding the problem....because spending 5 hours looking and trying to fix a slightly wobbly mirror will cost the customer some bucks. So I have to be careful with my time. It is more than likely different with you. BUT as you can tell...I have been 'there' before.

Thanks, Dub. It's a minor annoyance (like the fact that the head was loose to begin with... screw had fallen out from the mount. Take glass out, remove mirror, reinsert screw, reinstall mirror... to have it wobble again the next time I close the door. Insert superglue here...) but didn't know if there was something I missed. Might try some small light springs on each actuator arm just to provide some resistance to the glass. I don't want to put foam in there as it will hold water and affect the motor assembly. Stopgap measures until I find a replacement... unless the stopgaps work!
