I'm in the process of replacing BOTH front engine mounts on the E420. As of now I have the passenger side mount replaced (which is the easy one). It only took 2.5 hours, which considering the immense amount of room you have in the engine compartment with the V8
isn't too bad. (Solved 98% of the vibration and now it's easy to tell that the driver's side mount has failed when the transmission is in reverse.)
Now the question is how the hell do I get to the driver's side mount? The only post that I could find recommended that I remove the exhaust or ac compressor in order to get to it from underneath. Does this sound right? There is absolutely not way of getting to it from above.
Thanks in advance!
