Finally found the resulting problems from the rear end rebuild. You fix one thing and it causes another problem to become apparent.

By reloading the wheels with new shocks and springs and replacing all the rubber under the rear end, the wheel bearings on one side that were already going bad but not making noise, became noisy and apparent. Very simple. It is not the rear end giving the noise. My other noise was listed in the factory repair manual for the sub frame bushings. If they vibrate, you add an additional 2.5mm washer under the bolt.

I removed the rotors and cleaned all the parts with brake cleaner and blew out the dust. Glad I did, because my rotors need replacing. I took apart the calipers and will order the seal kits for them too.

It does not look like I have rear wheel camber issues, but I am going to have a four wheel alignment done and change the rear end lube and put in the factory recommended 90 weight Lubrication Engineers brand lube. This is the best lube you can buy. They run LE lubricants in corvette racing cars and in coast to coast big diesel trucks. Many who have been running it since new have over 1,300,000 miles on the engines with no rebuild yet. That's amazing. The local sales rep said the Mercedes dealer won't tell people about their engine oil because they want to make money on oil changes. It can go up to 20,000mile intervals. Big truck tested with oil analysis. But Mercedes has been using their rear end lube for 30 years.
