Engine mount replacement on 4matic?
I am trying to figure out if there is a way to replace the drivers side mount without removing the axle? Passenger side looks like you remove the alternator and it gives you access?
I literally just replaced drivers axle a month ago -- had I realized then I would have done it, but it is what it is...
Anybody done it and can give some ideas?




I did it some time ago, but remember removing front 1/2 of fender liner only on 1 side.
Either way I did NOT want to remove axles to replace the stupid engine mount!
Going to get two new MB mounts ordered tonight. When I did my trans fluid change my trans mount looked fine and my overall Mb experience has been that the T-mount lasts twice whatever the engine mounts do since they are not hydraulically filled and have much less movement.
No idea why you'd need DAS regardless? Seems just plain wrong...
remove both front wheels.
loosen lower mount bolt and upper mount bolt.
use jack to jack motor up enough to remove mount from wheel well area (mount is looking right at you when you remove wheel if you indeed have 4matic).
install in reverse order. tops 5-7 minutes a side if you are nice with tools/have skills.
if u have 4matic w211, nothing needs to be removed except for encapsulation panels and wheels.
they are literally dtf for removal. 13mm for subframe bolt 16mm flex ratchet for top bolt. 2 jack stands and obviously a jack. have fun.




So yes, if you don't mind some bending, nothing else need to be removed.
Hard to keep on topic where you have a clown, who never was under the car spreading fart around.
Why would the peachparts tech article tell you that you have to remove the alternator and axle?
I was going to be so pissed if I had to re-do the axle removal again LOL. Getting the axle shaft back in was a real pain...it just wouldn't line up and took me about an hour worth of frustration, especially in 110F heat in the AZ summer right now! (that was more likely the frustrating factor...)
Thanks guys. Got them ordered from mbdirectparts they are a great dealer to buy genuine from FYI and fantastic prices.

Professional mechanics will always paint bad picture, because that allows them to come with bigger estimate.
cmriv works for dealer as well. He will not hesitate to bend parts to save 2 minutes on removal simply because when the part cracks - it is not his car and he will get paid full amount anyway.
My latest purchase - pristine 2008 Bluetec -cost me about $500 in parts I had to replace under the hood simply because they were bend, kink and ripped during dealer's "service"
If simple MM can bring so much confusion, imagine what will happen when you come to SBC rebuild.

Most of my experience is with my 88 300TE, but unfortunately the newer MB's don't make the factory manual like they used to, so have to dig a little deeper now (even more so now they took away EPC)...I did the entire rear suspension, axle and subframe rebuild from the factory manual since they have fantastic photos and details...shame.
....Soon I'll be getting the Chinese DAS and I can scan myself! Got the Dell laptop for it, just need to find a good seller of the unit.

When 5,000 miles later I have front tires bold on inner edges, while still 4mm on center, I pulled my old scale to check toe. It was 4 degree negative, when it should be roughly 0-0.5 positive.
Good luck with the DAS.
I have carsoft I bought long time ago and I gave it another try this week. After spending like 3 hr to download the crack from 2 different discs I had, the software finally opens, but the multiplexer can't read the car.
Good part that $50 toughbook laptop I bought for it, is going to be excelent for GPS
Let me know how your DAS will work?

I jacked up the engine after removing air intake on engine using a 2x4 and a towel on top of it to protect the pan. I went slow though to not jack up any further than was necessary. There seems to be an updated mount design and its slightly taller. Had no issues though, so part was definitely right.
Total time was about 2hrs from start to tools cleaned up and done.






In the mean time on other topic a member used fancy engine lift for such job.
Looks good and simple, so next time I am due for MM, I will research the price.

That's the way I figured out without searching the net, so maybe there is easier way, but I also wanted to check alternator brushes and it was right call.
