I just picked up a used interior rear view mirror in nice shape, except the pivot ball mechanism is loose so that the mirror wobbles around. Is there any easy way to tighten these up? (IMG:style_emoticons/default/confused24.gif)

Thanks.

i dont think so; these are press fit, the metal ball goes into a plastic socket. I used a vise to re-install a ball into the socket. if there is too much play there I am not sure what can be done to make it tighten up.

I agree. If the ball and socket is loose that is it. the base will tighten with the arm via a brass screw though.

What I did on our 1974 street car was to put a dab of GOOP, the clear sealer stuff on the joint once it was aligned like we wanted it and let dry for a couple hours. No more vibration. That stuff works wonders for other things that need holding such as sheet metal screws that back out or nuts that you can not double nut.

It seems as though you should be able to pull the ball out of the socket, insert some friction material to take up the loose space in the joint (ie electrical tape?) and push the assembly back together, no?

Well, I guess I answered my own question. By pulling the ball out of the socket, inserting 1/4 inch wide strips of electrical tape in an overlapping basket weave layout (two layers thick) i was barely able to push the ball back into the socket but it did snap back into place. Now it has very little slop and we'll see how it goes. Check it out for yourself and resue and old mirror. (IMG:style_emoticons/default/shades.gif)

New mirrors are cheap, and the mirror is, well, "new".

The nylon electrical tape will give-up soon (hope I'm wrong).
Next time use some aluminum foil instead. If it works on crankshaft bearings (yes, kill me now), it will work on your mirror.

For folks who want an original mirror, kludge fixes are the only way, as Porsche stopped using/selling the original mirrors back in the '80s.

Yep. I used a 944 mirror last time I bought a new one.
