@benzmechanicc: In order to change the rear shaft seal of the GLS 63 AMG, you need to remove the gearbox and the Starter-Generator, which it’s not so easy! If you look at the WIS document it says you must remove the engine with the gearbox. Today i tried it anyway and it worked without removing the engine out! #mercedes #benz #work #mechanic #viral #lovemywork #gls #63 #amg #starter #generator #gearbox #engine #m177
