Many times the waxoyl stuff can get hard and start to crack and will accelerate the rusting process. Oil spray like NHOU or krown fluid film that you apply every year or 2 is the best stuff.


When I changed the bushings on my 300SE (almost the same design) I removed them with a screwdriver and when installing I lubed everything up with SYNTHETIC GREASE (important because it doesn't react with rubber) and placed a wooden piece between the subframe and the body and with a floor jack I pressed the mount into the subframe. I had a wooden jig pushing on the mount so that I pressed on the outside edges of the mount and not the middle.

I also had to have a second floor jack just holding the subframe because when you remove the big bolt holding the mount the rear springs will want to push the subframe to the ground
