A few months back my car started to develop a slight vibration at idle and a few constant RPM's while driving. Really wasn't that bad compared to other brands of cars but not quite right for an MB. Last time I changed my oil I noticed the drivers side engine mount was leaking. I purchased mounts at that time but didn't install them because I was busy. I lived with it for about two months and as time went on I got used to it and barely noticed the vibration anymore (it was not severe). Last week while passing someone on the highway the car downshifted and it sounded like the muffler was right up against the floorboards under my feet. I knew the mount had just given up. From that day forward the vibration increased and was really bad in reverse.

Today I decided to swap the mounts. I looked up the DIY on benzworld (for an E320) and it looked fairly straight forward. When I got my car up on jackstands I noticed the V8's were way easier then the V6. I had plenty of room to slip the old mounts out with out removing any belts or moving any AC components out of the way. The only real tools you need are an 8mm for the belly pan, 13mm for the bottom bolt, 16mm for the top bolt, and a jack. Real easy. Took me less then an hour and a half including the time to jack the car up and dig out the right tools. The only hard part is getting enough leverage to loosen the top bolts.

Car feels smooth as glass now! The slight vibration I had learned to live with is totally gone and I now notice it was worse then I thought. If your car needs mounts don't hesitate to try this project (especially easy with a V8) even better the parts only ran about $110 bucks shipped off Ebay.

 

I have been wondering about the same thing. My inlaws W202 C250 diesel feels way smoother when idle and at certain rpm's when compared to my W210 E220 diesel right now. I have a feeling that I'm living with the same 'slight vibrations' and that it'll be the same experience when I get the engine mounts replaced at the next large service interval...

Can you post the DIY link from benzworld! THX.

 

Heres the link.

There are two DIY's on that thread. One has pics and the other has a link to another site with different pics.

 

better is the mounts are on sale for $100 the pair at
http://www.autohausaz.com/search/pro.../Motor%20Mount
free shipping and you are certain they are OEM.
Did you take pics?Post them for the other members so they can see before and after.What a diffference

No pics. They looked just like everyone else's pics. The drivers side was cracked all the way around and leaking fluid. It was also compressed almost an inch. The passengers side looked OK but there was some indication of small cracks starting to form.
$100 from Autohauz is a good deal.

 

Replaced mine a few weeks ago, along with shocks (Bilstein) and cats. Can't imagine why fixing the suspension, an exhaust leak and attaching the engine to the car would make such a big difference!!! ;-)

Pic attached of the old mounts. I'm not sure if they were bad though! hehe

 

Weather permitting I will be changing mine this Thursday or Friday. a quick oil change while I am at it. Taking a roadtrip this weekend and I want the car runnig right.

 

Does the 4matic utilize the same mounts?? My car is doing the same thing, super super rough idle. If i rev the car up to around 1000-1200rpms it goes away.

 

The engine mount for the E430 is a different part number than the E320

 

Ok, I just finished changing out the motor mounts last night. Not an easy job for people with big hands. I tried the stubby ratchet on the driver's side top bolt and couldn't get enough pressure on the stubby handle to crack the bolt. Lucky I live near a Home Depot and purchased a infiniflex ratchet http://www.homedepot.com/webapp/wcs/...StoreNum=8125\
This did the trick for the top bolts on both sides. The rest of the install was a breeze. This weekend I will tackle the tranny mount.

 

i know the v6 utilizes different mounts than the v8, but are the two v8 mounts different? non-4matic vs. 4matic? Anyone done this swap?

 

I'm also interested in replacing them on my E320 4Matic. My concern is if the front propeller shaft will interfere with the procedure or not. Maybe it needs to be removed. As far as parts go, they're likely to be different from 2WD cars but fairly the same thing.

 

I just wanted to say kudos to those who do such extensive maintenance on their personal vehicles. Personally, I do what I can (washing and waxing) but I still leave the majority of the work to be done at the dealer.

Those who work on their cars themselves to the extent of replacing things like motor mounts demonstrate their desire for something to be done right. Because if you want something done right, you have to do it yourself.

 

4matic motor mounts are different, but im also wondering about the procedure.

For those wondering, the 4matic mounts are about $80 each at Duval Motors.

 

does the 01 E55 use the same mounts as E430? i might do this next spring. anyone around SE MI wanna do this together..?

 

50 bucks ea.

I'm goin to order a set for my 4matic this friday and when i do the job i will do my best to make a DIY thread to help all you other guys out.

 

awesome man, I would appreciate it.

Even one persons tips will be helpful.

good luck.

 

Look forward to it! Cheers.

 

any updates on the 4matic mount swap?

 

My mounts were done today together with a large service and annual emissions. What a difference! The Diesel-hum/drum is much less noticable when idle, and at high rpm's I now only 'hear' the engine revv instead of also really feeling it everywhere. The shop showed me the old mounts, they were the orinal ones marked '1997'. They also told me it has nothing to do with mileage and that this'll make a change on any 10y/o benz...
