The mounts are cheap, like $32 or thereabouts from Mercedes. Don’t buy aftermarket mounts! Do the passenger side first, as it’s the easiest. 1.) Take out the fender liner 2.) Remove the nuts from the mount - 1-18mm on the top, 2-16mm on the bottom. You can get on the top nut with a ratchet, the bottoms ones with a ratchet and some extensions. Make note of the heat shield on the top of the mount, and the presence of a flat washer under the top nut. 3.) With a floor or bottle jack, use some 2” x 2” boards to clear the crossmember and sway bar to jack up the engine using the oil pan - be sure to use a long board to distribute the weight across the pan. Take the plastic cover off the engine first, then disconnect the air cleaner outlet to the MAF so the engine can move upward. Jack the engine up (gently) until it “tops” out. Watch the back of the engine and the coolant reservoir as you do this so you don’t break anything. 4.) Disconnect the battery, as you’re working in close proximity to the starter and alternator, and there are exposed terminals with battery voltage on them in this area. Using a star socket, remove the four bolts holding the engine support to the engine. 5.) With the engine support loose, lift the mount out of the frame. 6.) Place the new mount into position, making note of the “Front” marking on the mount so that it is facing the front of the vehicle. 7.) Reverse the order of work and you’re in business. Differences between the right and left side mounts: 1.) The left side mount requires the removal of a heat shield as soon as you remove the fender liner. Three 10mm nuts and the heat shield lifts out the top of the engine compartment. 2.) The bottom nuts on the left engine mount are a little tougher to get to. You’ll need a 3/8 universal and some long extensions to get to them. There is a hose in the way of one, but it can be easily pushed out of the way. 3.) An 18mm ratcheting box end wrench is a big time saver in removing the top nut. It’s in a tight space and will take a while with a standard offset combination wrench. No room for a ratchet/socket on this one. 4.) The engine support star bolts are harder to get to on the left side, but can be done with a 3/8” universal and some extensions. There is an additional star bolt that goes through the AC compressor and into the engine support. This has to be removed in order for the support to move around and clear the mount. An hour for the right side is about average and two hours for the left if you’re not in a hurry. -D > On Jun 22, 2022, at 8:01 PM, Buggered Benzmail via Mercedes > <mercedes@okiebenz.com> wrote: > > I think the mounts on the 05ML500 are shot, probably what the clunking is > I’ve been hearing.
