The WIS procedure for the 4Matic, unfortunately, calls for the disconnect of the O2 sensor and the removal of the exhaust pipe, for the left (driver) side engine mount.

Maybe you can post this in the 4Matic thread. I can later upload the WIS doc for this.

Right, PAX "side was done easily".

Thank you SO much. I do NOT have a problem removing the exhaust pipe. This procedure makes sense to me. If I'd known, I wouldn't have removed the serp belt. The car remains on the stands tonite, gracias! Benzworld saves again! (Will repost pix to the 4matic sticky!)

The engine mount DIY posts are old, so I want to make sure the proper thank yous get sent out.
Very big thank you to texas-patrick and G-AMG for their DIYs on motor mount replacement! I finished the job today and OH MY GOODNESS what a difference! I have seen posts where people have said their gas cars felt like diesels when the mounts failed. That was me - now the car feels like it rides higher, smoother and quieter and yes I am enjoying the ride! Awesome and I can't thank you enough for the guidance - you saved me major $$!

I do have some comments about the DIYs and other posts from other owners in hopes that I am making a contribution (I am a shade tree mechanic with no access to a lift):

1) Space in doing this job is VERY limited. I have larger than average forearms. Doing the passenger side mount wasn't that much of a problem when it came to space. The driver's side was different. I employed someone smaller than I with strength to get to, unbolt, and replace the top side motor mount bolt. I couldn't get to it seemingly no matter what I did. So, a small payment to a kid that needed it - no big deal.

2) If your mounts are leaking oil as mine were, BE CAREFUL getting them out from beneath the car. The oil can end up in places on your face you don't want. It missed me, but that stuff is nasty!

3) I used rhino ramps for the car and a 4 ton Craftsman hydraulic jack to jack the engine up higher for removal and re-installation. Once replaced, especially the driver's side, it is easier to let the engine back down to fit the bolts correctly.

This is NOT an especially difficult DIY - but BE PATIENT and vigilent and you'll be absolutely pleased with the result.

Again, thanks to everyone for their posts and help!! I'm hooked and pondering a higher level of membership!
