I checked into labour times on Mitchell its approx 3-4 hour job.They said that it was 13- 14 hours. The mounts are only $325. Has anyone ever had this job done? Please report. Thanks Mike It is relatively easy job, and I would not pay more then $300 for it (300 - just because I am lazy). But also, it could be done without the lift, but MUCH easier with one. P.S. - check those mounts on parts . com - $325 sounds way too much.

It's probably happening above 40 but you can't hear it.

Bushings in the swing arms
Loose strut
Defective strut

Yesterday I installed 2 motor mounts and 1 transmission mount Iam very happy to inform that the clicking/ rattling noise at slow speeds from front end is gone. Dont get ripped off from the mb dealer to get this job done it took less than 2 hours to do . I got quoted 14 hrs. labour. Hope you get your problem sorted out. PS I also replaced the ball joints first. Regards Mike

[supa_sta]

to be honest its not a rattle im hearing,its like a severe knocking sound,actually yeah u could be right i also do get a rattling sound like as if u got a few stones in a plastic bucket and wen u shake the bucket with the stones in there that kinda sound too,lol hope ive explained it good enough thnx ru sure its more likely the two rubbers and trannsmission rubber

Well then... welcome to the club! What you described earlier is exactly what I am getting for a year now - "sound like as if u got a few stones in a plastic bucket". Accept I don’t get it on speed bumps…
Replaced a lot of stuff by now (not for fun, but because those needed to be replaced).
Going for Link ball joints and bushings now.
Motor mounts after that. And if all this does not help – for a new E class!

hello rostov ur right im having the same problems u was having and it pissing me off,its been like this over a year and know one at mercedes seems to know what the problem is,they want me to change everything and still not garnantee it will fix the problem and by the time they finish i will be bankrupt lol.its a shame the warranty has run out otherwise i would have worked them lol,so did u do anthing to your car to fix the problem or is the problem still there?thnx

[rostov]

For some strange reason this noise has disappeared after tire change and alignment. But 1000 miles later it came back even stronger. After last check, I am going to replace those parts that I had specified in my previous post with picture, and will see what happens.

[bigsmile1130]

It would be great if you could write up how you did it and a few pics might help others doing the same work. vettdvr

the thing that has pissed me off is my care broke down last 26th wednesday,with starter motor problems,got AA recovery ppl to recover my car to mercedes on a recovery truck,they have charged me nearly £800 for a new starter motor and they havge also mentioned that the AA recovery ppl have damaged my front suspension too,they show me the extent of the damage that was visible and im not happy,i have made a claim against the AA.any one here that can advise me about this situation?

Remove plastic covers from under engine. Use a floor jack with a block of wood place under oil pan, Remove bolts from both engine mounts, remove air filter housing. Jack up engine carefully just enough so mounts are loose then slide out the mounts slide in new mounts then tighten everything back up then you are done.

Would this work on the V8 the same way?

[bigsmile1130]

The motor mounts that I replaced were from a 2004 E500 4 matic ( V8)

Black smoke is usually fuel rich.

Do you have any computer codes.

O2 sensors failing putting the system in open loop
MAF failure
Injector sticking
Fuel regulator

Just to list a few. To answer for sure you will need more data.

Fuel mileage dropping is a good indicator of fuel rich

[supa_sta]

thnx for reply,ive had the e320 cdi go thru a diagnostics and mercedes told me its ok and its normal for the e320 cdi to give out blck smoke when u put ur foot down,but ive heard different by other ppl that it shouldnt,someone mentioned its could be the egr valve,but the car drives ok,the power is there.....really dont know wat to do

If your fuel mileage is where it should be then don't look in the rear.

One sure way fuel rich will show up is in increase fuel usage. This is normally black smoke. The engine does go rich under full acceleration to give it the power. So it is possible what you see is normal.

Excessive fuel can also fowl plugs and dilute oil, but my guess is you have none of this and it "might" be normal for you engine.

Yes My engine was idling rough and I took it in. They found the mounts leaking and failing. They replace both engine mounts AND the transmission. All is back to normal now.
