i have a 190e 2.5 16v, i am going to be replacing the diff soon with a replacement. the car has asd so is in the same hydrauli system as the sls rear end. becasue i have to break the system to install the new diff i assume i will have to bleed/flush the system afterwards. will this procudure work on my car, i noticed a bleed valve on the diff itselft but seeing as its a return valve system MikeTangas suggestion seems like a good idea for me as well. can someone confirm? many thanks, steve.
