Hi all,
Thought I'd share a hack that I learned about with other makes that has been used on my w124 300td and could apply to other models as well.

Disclaimer: I advocate proper repairs most always, but at times, if you are in a pinch, or just want to delay a real PIA repair, a hack can come in handy.

Having done diff bushings before on this car, and as most, found it a real PIA, I had little desire to face this again after finding some missing rubber chunks in my current rear bushings. I decided to inject an expoxy compound into the voids to restore firmness, and after a month so far, am quite pleased with the results. No more clunking in the rear.

I used jb weld clear 2 part epoxy with the self mixing injection nozzle for ease of application. Depending on how much you need, you may need to create a damn with masking tape to keep the epoxy in place. Thejb weld is fast set, 5min, so works pretty well and is compact enough to do this job. Other alternatives include, injectable rubber, silicone and similar compounds, most will depend on ease of access, drying time, flexibility and application methods with injection being the best. The jb weld is available at most big box stores.

This method is used in several Japanese cars, where the diff bushing, mount, is not considered a maintenance part an requires the purchase of a new and expensive subframe assembly. Thus the idea was born and successfully employed on thousands of cars.

I plan to continue with this as needed until I ever need to drop the subframe to do a bunch of things at the same time and replace the diff bushings then. I'll report back with more long term results.

Hope this is of value to some of you.
