I did the mounts on my '94 E320 about a year ago. I removed the fan shroud and jacked the motor at the pan enough to take the weight off the mounts. I had to remove a heat shield on the exhaust manifold side. The other side was much tighter, but manageable with no part removal to get to the mount. I removed the bottom bolts and then jacked the motor as high as would permit and replaced one side at a time. Kind of a balance-push-pull act with a few blocks of wood &some 2X4s. I did not use anything more than a the typicalcompliment of wrenches, sockets, extensions and swivels.
