When I rebuilt the front end on my 300SD a couple of years ago, I used a Febi GRM which failed about a year later. To make sure that it was the GRM that was making the popping sound, I pulled a $13.00 L bracket with GRM in it from the junkyard and that worked great for about 6 months until it started creaking. I was in the yard again the other day and I took a peak under a 1986 560sel and by the look of things, it appeared as if the suspension had some work done on it. The sub frame bushings were clean and soft, and after I removed the L bracket from the car I checked the firmness of the GRM and was surprised at how much effort it took to move the threaded nipple side to side.

After installing this L bracket with nice bushings and firm GRM, I was shocked at how good the car felt when taking slow turns around town. The steering actually feels tight like a German car should and not like a GM boat from the 70's . I was lucky to find a good used one in a CA junk yard, but if you live in a part of the country where you'll have to buy new, I highly recommend a dealer part for this repair.

I'm heading over there in about 1/2 hour to do that. For $13.00 how can I not?

wonder if a hole can be drilling in the back of the guide rod mount so that one could install a grease fitting and fill it with grease, i think this would extend the life of the joints by many years.

Though in this case the problem was worn bushings holding the guide rod mount holder to the frame. a 126 peculiarity.
