hi all,

just curious, do you need to separate the engine from the tranny to replace the engine mount. local mech is saying this and not sure if he is just trying to make it soud a lot of work to jack up the labor cost more because of that. thanks folks

Plutoe

post your VIN!!

Here you go

The answer to your question is NO------however, if done the factory way you remove both R and L cats, remove R and L axel shafts, remove alternator, remove the R side exhaust manifold----plus all the little crap in between.


If I were you I would make damn sure I need mounts and then let him do the job the way he thinks it should be done!! Have a blessed day!!

Sam.P

No, I've done them myself and the only things you need to remove are the alternator/compressor (just needs to be unbolted from the block) and both front axle shafts if your car is 4Matic. Unbolt the two mounts then lift the engine from under with a jack just enough so you can fit the new ones in.

Thanks sam p I was told the same thing but decided to hold the repair coz the labour charged Increased and they won't be able to get it done the same day. I will have to reschedule this

FYI engine mount and tranny mounts replaced and car is running super smooth. I more shake your headlights. Thanks you all

what was the cost for just the parts and just labor?

monarc98

Here where I'm at cost me a little less then usd 200 for the parts . Labor was a bit cheaper 215 usd

AzCamel

OEM parts? Thanks

monarc98

Correction on the cost it's 297 usd for labor and around 225 or less for the mounts 3 pcs. Yes all original got decent price from benz store (reseller)

Just did it on a 2WD model:

I replaced all 3 motor mounts (2 front and transmission) in December 2013. Only 24,000 miles on the odometer since the replacement. I have learned that I need to replace them again. I have no doubt about the competency or honesty of the mechanic. He said that he was not surprised and that it was highly unlikely that it had anything to do with my driving.


Has anyone else experienced such a short life for your motor mounts. I have a 2004 E55 AMG with 101,000 miles. It has an R1 RennTech package (if that has any bearing on this issue, which does not seem likely)

I had a 98e and an 05e and both went thru motor mounts. the 98 2 sets over 105k miles and the 05 85k. It's a common issue with Mercedes.

What are the symptoms of bad motor mounts?

I appreciate the response. I will resign myself to this expense every 25,000 miles.

The engine feels like its sitting on the frame when running and you can feel it as a vibration when you're stopped not the isolated ride you expect. You also can check the mounts visually and look for hydraulic oil spots.

AzCamel

Easiest way to diagnose motors mounts is open the hood, have someone inside the car with it running, tell them to hold the brakes all the way dow, put it in drive and blip gas, if the engine moves up/down or sideways then your mounts are bad, especially if the engine looks like it wants to jump out of the engine bay. Another way to tell is put the car in drive and see if there are vibrations, then neutral and see if it goes away.

I had to replace all the mounts on my old E500 bit it did last 100k.
The issue is with the hydraulic design of the mounts, most cars with this design like my 08 Acura TL will cause failures much faster then normal, I would gladly use non hydraulic type for a little bit more vibration for longevity

Hugo L.

Ah, thanks for the info. My car just hit 60k miles, and so far so good.

mjhawkins2346

I guess I'm lucky. I have 111k miles on my 2010 GLK 4matic on the original mounts.

sethro1980

Mine got replaced at about 30,000 miles. 2013 GLK350 4Matic.

NYCGLK

Same here 2010 with 70k miles, but I do notice a very slight vibration, which I think is an indication of the mounts wearing out.
