Tips on Installing Window Regulator Rebuild kit? (End of Lifter Arm)

Hey all,

The plastic piece on my front passenger window regulator broke a few months ago and I've finally gotten around to ordering this part to fix it; 123 720 01 14.

Any tips on installing this, especially regarding what order the parts should go in? I see one white plastic piece that looks like 1/2 the old one so I assume that forms the base, but the small spikey piece and different washers have me a bit confused. I appreciate any assistance!

Assuming your post is still good, the square one goes on first. After conn to window channal the the white round one, the star washer and the clip. Dont know about the other parts.

Also don't forget lube on all pivot points and the slide.

A good lube is Kluber Isoflex Topas NCA 52

If you buy from MB this is what they ship.

It is a good lubricant that wont dry and gum up over time.

Mercedes part number 001-989-37-51-09 @$16.28  not anywhere near as much as Amazon wants for a tube = $40-$67!!

Aaron recommending this a few year back for window regulators.

Thanks, Rumb! Got the parts, but I can't quite tell where the clip is supposed to attach to. Is it a part on the regulator itself, or the metal peg that goes through all the pieces?

Metal peg on the end of the arm that the white washers go on.

Is this the clip I need to fix my passenger window moving forward and backward a bit when I'm closing it rather than straight up and down? 

I'm planning to open up my doors and lube all the window mechanicals soon. I want to replace the broken piece that's allowing my window to wander at the same time.

I think this is that piece. I just happened across this string while researching which lubes I should order for the gears vs rails vs glass channels. I love all the info in this forum.
