Rear-View Mirror Vibrating.

This isn't the problem. I had this CIPA / Magna Donnelley mirror installed for a long time w/o this vibration issue.

To combat this try sticking some mag wheel weights on the back as far forward as possible. Discount tires balances my tires pretty much on demand so that's not a factor for me. IFIRC my Broadway is a 360 mm. The first one I bought just wasn't wide enough but is perfect in my pickup.

Stock ball socket? On the stock mirror?

Anyway, I've kind of fixed this problem by zip-tie-ing the RAM mounting base to the base of the mirror. There's hardly any vibration now. Before the zip-ties were applied, I had tried adding some anti-vibration foam around the wedge on the RAM mounting base (that the rear-view mirror attaches to) and that didn't really help.

I'll try to post some pics. later of the "fix".
