Both mirrors on my 1983 300 D are seized. How do I get them apart in order to lubricate them? Thanks.

I assume they are both mechanical, or is one power? You could try spraying some penetrating oil or WD40 into the mechanism and trying to squeeze the mirror outward with both thumbs, being careful not to break the glass of course. If that doesn't work, they come off of the car real easy, just get the plastic handle off and remove the silver plastic cover. Both just clip on. Then there are only 3 screws to hold the mirrors onto the doors. You can try to get in behind the glass and free whatever is stuck. It can't be that rusted, if they are that bad I got one for $75 at the junkyard. I hope this helps.

The mirrors themselves pop right out...they are held in by a ball and socket joint ....go easy and try to avoid breakin the mirror. Its a good idea to remove the entire assembly. At the bench, clean all contact surfaces and grease all parts. You want to use a good water resistant, tenacious (good staying) grease....good choice is syl-glide (this is flexible at very cold temps, water resistant, very tenacious)

Note on syl-glide....silicone grease is NOT a good choice for critical high pressure applications (wheel bearings and such). For those applications, you want to use a good petroleum based lubricant. But silicone grease is one of the best choices for low pressure "slide paste" applications....mirrors, sun roofs, throttle linkage etc., and for lubricating rubber parts (installing bushings, protecting rubber seals etc.) as it doesnt degrade rubber.

When you say they just pop right out are you talking about the glass or the whole exterior part of the assembly?

I think that the glass is bonded to a backing plate which has the ball mechanism on it...

I took them both apart, greased them up and they're working fine. Thanks
