1995 W124 E320 Window Regulator - PeachParts Mercedes-Benz Forum

On my right rear window regulator (See pics) the white square part that lifts the window rotated on the rivet 180 degrees so that it is closest to the blue wheel in the picture. (The pictures included show everything in the correct position, I didn't get any before we "fixed" it.) With it rotated the window would not fully close (about 3 inches short) and it eventually fell off the track down into the door frame. We got it all put back together and it looks like it will work for now. I'm sure it will happen again. So the question is; is this the right part to fix it: attached picture: "Sliding Jaw window regulator.jpg"

Thanks!
Dave

I've replaced sliding jaws before, but not on that style regulator, only on the older ones (no cable, all gear type), if you want to try that fine, I'm not sure how you even get the jaw out of the track. Worth a try of it's cheap enough.

That sliding jaw you have pictured is for a 202 chassis car, or possibly the front window on your car. The only fix for your car is a new regulator/motor assembly.
On your regulator two tabs have broken off of the gray plastic slide which keep the white plastic jaw from rotating out of position.

Thanks for the help. I thought the replacement jaw didn't look right. Just ordered a new regulator from Peach Parts. I'll post pictures of the installation when it gets here.

Next question: do I need to lube the new regulator and window tracks? Lithium grease maybe?

Here is a picture of the white plastic piece in the wrong position.

Got the new regulator from Peach Parts. Sorry no pictures, it was getting dark and wanted to get the car back on the road. New one doesn't come with the eye terminals on the wire. But I was able to strip them offf and match them up. Works great. The replacement is designed so it can not fail as the OEM did. Thanks Peach Parts! $114 for the part and $28 for overnight FedEx. E320 back on the road!

WOW was that ever fast!
You shouldn't really have needed to lube anything, even the sliding jaw doesn't really "slide" like they used to on the old ones, just enough sliding to allow assembly and some minor movement if req'd. The old ones moved back and forth alot and we used to use the same lube in the tracks that was recommended (sold by MB) for the sunroof sliding jaws. Most any grease paste will work as long as it doesn't get gummy or sticky, especially in cold weather. "Lubriplate" is another good choice, this originated with GM but I think got spun off and you can find it at big box auto stores now. Best stuff for power seats!

The new part was pre lubed right out of the box. Working great.
