RR Engine Mounts - 99 C280

Hi guys,
I am planning to do this DIY at my house. So wanted to run by the following if someone has done it on a 99 C280 also -
1) Following the WIS instructions for 99 C280 (Model202.029) V6-2.8L (Engine 112.920) - good?
2) Don't have an engine lift so will use a jack and 2x4 wood to raise/lower engine - is it okay to put the wood under the oil pan or is there a better location from under something else?
3) Is it absolutely necessary to A) unbolt the steering damper at the drag link and then B) detach the drag link from the Pitman and the Idler arms?
4) Are the top bolts of both the mounts unscrewed and screwed back on all from the bottom of the car? what is the tool that will work best for this part - 'cause this seems to be the most challenging part of the DIY.
5) Will the old mounts come out and the new mounts go in, both from the bottom?
6) Right after, I will also be replacing the rear mount but that looks much easier than the two engine mounts.
Thanks much in advance for any tips/advice/heads up from someone who has done it on the same car - will definitely boost my first time confidence
Thank you!

Welcome sgoesbwo,

Yes to everything except for (3) - not necessary. Turn the steering wheel to the right (ps).
Note: The ps motor mount has a silicon heat shield that needs to be used. DS does not need one.
For (4), top bolt removed from topside, bottom end nut removed from bottomside.

Here's a DIY video that's self-explanatory.

Keep us posted on your DIY project here.

Thanks khomer2,
I'll keep your suggestions in mind and will definitely post back what it took to get it done.
The video is on a M111 engine whereas mine is M112 where doing anything from the top doesn't look possible??!!
While I realize procedures can overlap between several models/engines, did you actually do this yourself on a 99 c280?
best regards!

Ive only worked on a c230K. Anytime I purchase a used car, I check to see which models are DIY friendly.

Here's another link that should assist.

Try using the search engine, you'd be surprised the wealth of knowledge other members have posted here.
Read, read, read.... dont stop.

Thank you khomer2,
Yes, I had seen and bookmarked that link...the feedback from Hookster and blackiron56 are pretty useful. You're right, reading as much as you can does help clear a lot of confusion as a novice...it's 90% planning and 10% execution
A question though if you or someone can answer -
WIS instructions don't include moving the AC compressor or alternator but does instruct to A) unbolt the steering damper at the drag link and then B) detach the drag link from the Pitman and the Idler arms.
Which is simpler? Cause I am thinking following WIS method could potentially call for alignment check, which will have to be done at a shop at additional cost...

Hi duh_vinci,
Thanks much for the video link! I had actually seen and bookmarked it but had ignored it with the incorrect assumption its not for my car. When I matched its engine information you provided in WIS, I was pleasantly surprised to see the RR docs for the two cars are the same. So I watched the video again and this time it was as if I was looking at my engine Amazing how I was lost in the sea of information during my research! Thank you, now I think I can go work on my car!
ps,
1) if its of any significance (which I will find out once I get on it), I read somewhere someone is using a stubby ratcheting 5/8 or 16mm wrench for the top bolt of the mounts. Again someone wrote he cut off his regular wrench to make it stubby!
2) I had someone try the top bolt before I got into all this research, pretty strong guy but he was unable to unscrew the ds top bolt from the bottom. The car was on stands and he hadn't loosened the bottom bolt yet and the engine wasn't yet resting on wood and jack. Someone did write his DS top side bolt was pretty hard but he eventually unscrewed it! Maybe we should use some penetrating oil?

sgoesbwo,

As I said before, Ive havent removed MM on a c280 m112 before, but after reviewing duh_vinci's video post, it looks like a pretty straightforward job, only tiresome to have to move the compressor to access what you need to access (MBs engineers' way of saying FU and pay us to do the job...)

And yes, use penetrating oil spray. Makes life easier. Brute strength to loosen a 'hard to access' nut?? AND then have it snap on you after all that preparation work??
been there, done that, No thanks.

Use this, this helps a lot.

There is no need to disconnect anything related to steering or linking or whathaveyou.

Take out the 3 bolts holding on the AC compressor to the block, shove the compressor forward, and you have enough room to take out the MM on the driver side.

Passenger side is easy, just need to play tetris as you maneuver the old and new one through the stuff blocking the way.
