Driver's Side Window Absence Guide

Toodiesdad

The driver's side window in my just acquired 1973 450SL is rattling and displaying excessive play. I disassembled the door panel and discovered that the guide at the bottom rear corner of the glass seemed to be missing. Is this component accessible independently from the glass, or must I replace the glass/guide combination as a whole?

Several other inquiries:

Which grease is advised for the window guide channels and pivots?
Should this vehicle be equipped with glass scrapers in the doors, and if so, could someone direct me to a supplier for them? I could not locate them in the MB parts list.

Have you examined the bottom of the door?The guiding blocks detach and get lodged in the obscure depths of the door's base. Thoroughly clean the surface and reattach it using urethane or silicone adhesive.

One of my items was entirely gone; it seems a prior breach had removed it from the door. I located a used replacement on eBay.

I did not see it at the bottom of the door, but I will examine it again. It is evident that someone has already occupied the space before my arrival. It is prudent to seek a new block on eBay.

Which grease is advised for the window guide channels and pivots?

The original substance seemed to be white grease, maybe lithium, but it had dried and petrified, resulting in little lubrication activity.
I used the conventional materials for ball joints and wheel bearings; maybe I erred, but somebody will ascertain the truth in fifty years.

This morning, I visited a you-pull-it salvage yard and extracted components off a 1975 450SL. I was unable to remove the whole window from the door due to a jammed regulator and lack of energy; nevertheless, I discovered the necessary window guide at the bottom of the door. It likely fell out the window, similar to what occurred in my vehicle.

What specific urethane did you use for the reglue, @sandra? Should I use standard RTV silicone or construction glue from the hardware store?

Excellent score!

I used normal silicone caulk from the hardware store, specifically designed for exterior applications, if I recall correctly. It is necessary to let it to cure for more than two days; I reinstated mine after one and three-quarters days, and it detached from the glass when I used the window.
I have utilized urethane gutter caulk from hardware stores for similar tasks; it may have a marginally shorter curing time in high humidity. However, unless you have numerous applications, purchasing a cartridge is not advisable, as they typically expire within a month of opening. Smaller tubes of RTV are available for such purposes.
I remember fabricating a spacer from pieces of rubber bands to maintain the glass's alignment in the gap on the guide while the adhesive set. The glass was first secured using rubber-impregnated cloth and a press or hammer; utilizing a liquid does not inherently ensure the glass remains centered in the gap.

Eliminate the remaining three and clean them, along with the glass; address all of them, since they are likely to detach imminently if they have not already done so.

I choose to use a segment of bicycle inner tube between the guide and glass, adhered using contact glue. The rubber of the inner tube had the appropriate thickness to provide a snug fit between the guide and the glass. The adhesive's box asserts it adheres to rubber, metal, and glass. I purified the components with acetone before to applying the glue and assembly.

I will reconstruct it in a few days and provide feedback on its functionality.

I am writing to inform that the window guides adhered to the glass, as mentioned in my earlier article, seem to be functioning well. I will use the same technique to the passenger side window guides when I disassemble the passenger door.
