For what it's worth, I replaced the motor mounts on my 2006 S500 4matic just a few weeks ago it's even WAY more simple than the service manual suggests.
I was able to do both sides in 2 hours and didn't need to mess with loosening the steering rack or removing axle shafts etc. Now that I know how it's done, I can probably do them again (next time) in about 1 1/2 hours..

The right side comes out from the top-
Just remove the serpentine belt, alternator mounting bolts and move the alternator out of the way so the mount will come up through the area normally taken by the alternator.

The left side comes out from underneath between the sub-frame and the engine oil pan (you need to remove the plastic cover under the engine bay). Just remove the 3 bolts that hold the cooler lines in place to the oil pan/block so you can move the lines out of the way (they have rubber hose sections so you don't bend any hard lines doing this) and you can snake the mount in an out from that opening.

For me, I removed the white rubber covers off the mounts just to make them easier to handle while getting them into position and then slipped them back on once I got the mounts into position (before bolting them down).

If you're careful, you don't even need to disconnect the battery (I didn't) and you will obviously need a floor jack to support and lift the engine slightly to remove/replace the mounts.

Probably one of the easiest jobs I've done on this car.

Outstanding news. With this information and the low price of engine mounts, no reason not to change them with any vibrations.

When you say cooler, I'm assuming you are referring to the transmission oil cooler (or power steering?)

thanks a bunch.

 

Ollie, it looks like we have the answer we were looking for from ezobens. Thank you brother ezobens!

I will go ahead and post the WIS procedure documents anyway just so that you have them as promised.

(The dealer would have charged you the book rate which would have included the R&I of the entire front axle system.)

 

Bob,
thanks again.

Good info in this thread that makes owning these cars much cheaper.

 

Just as an aside, (see attachment).
Add in parts at dealer list and you are probably looking at easily a $2k+ bill to do all three mounts!

 

Thanks, gents - added to the Encyclopedia under Engine. :thumbsup:

 

Thanks everyone for the info. I am going to do mine at some point

 

Thanks for the gr8 write up! Is this procedure the same way for a S55 removal of the engine mounts? :dunno:

 

I really want to thank Ezobens. His method worked perfectly and me and a buddy knocked this out in a few hours today.

If we weren't fighting to put the alternator back in (the clearances are super tight), it would have taken about 2 hours.


MB dealers are making a killing on this because I'm certain they aren't following the work shop manual method. I imagine they could do this in about 1.5 hours and charge for 7.

bastards.

Thanks ezobens, engine feels great.

 

Thanks for the gr8 write up! Is this procedure the same way for a S55 removal of the engine mounts?

Any of the Mercedes Vets out there would like to chime in and give me an answer plz???
Thanx

 

no, the s55 doesn't have the 4matic equipment, so its more like the standard RWD procedure thats shown in other write ups.

 

Hello Tony, and welcome to BenzWorld! It's always good to have another member that enjoys maintaining his/her own car. That's what we're all about around here.

Please take a moment to fill out your user profile with at least the following info.

1.) Specific model, and model year, of your car
2.) Whether or not it's a 4Matic
3.) Your general location in the world (country is fine)

The reason we ask for this is that MB made certain options available only on certain models, during certain years, in certain countries, and we do have an international membership. I happen to be from the USA. Others are from the UK, Australia, Nigeria, Lebanon, Japan, and so on.

Thanks in advance, and again, welcome!
