I know it's odd but I've never noticed the noise unless it's really hot out and going over any bumps. Kind of sounds like the springs and coming from the front. Anyone else run across this? Car has about 60k on the odometer.

Mine makes a really peculiar squeaky noise. It makes me think of fresh rubber sliding over metal. Kind of a creaky squeaky noise. My suspension is still stiff though so I've never bothered to look into it.

trbo2nr

Since I haven't done the suspension mod just yet, I will pull stuff off this weekend and take a look.

Biscuit

Is that the same kind of noise yours is making? If so, let me know what you find when you have a look. The noise does get irritating sometimes.

jturkel

you get this sound when going over bumps and it comes from the front end? check the motor mounts. i had this problem for 2 yrs and it took me forever to diagnose this. replaced motor mounts (thankfully still under warranty at the time) and havent had the problem since

trbo2nr

Yep and will do.

trbo2nr

Wow. I would have never guessed that and can see why it was hard to figure out. Mine makes the noise just driving with the slightest dip in roads, man hole covers etc. It's to the point people turn and look at the car......I gotta get this to quiet down!

jturkel

yup thats how mine was. i always thought it was something wrong with my suspension. i took many MB techs on drives and, of course, i could never duplicate the noise. when i did, they still couldnt figure out and i would get the car back with noises again. eventually, i finally got a knowledgeable tech to come with me on a drive and i let him drive it. and he just flat out said "motor mounts are bad".....so they replaced my motor mounts and my tranny mounts while they were at it under warranty. and i havent had that noise since. i'm not saying this is 100% your problem, but it sounds like it could be and i would definitely at least get them looked at or inspected

What kind of mileage do you have on yours? I will check them out as well- thanks.

jturkel

i currently have 82K on mine. though i noticed the noise i think around 45-50 and had it replaced at around 55 or 60. its been a couple of yrs.

Biscuit

Well. I sure wouldn't have expected that. I'm overdue on a service B anyways so I'll get that checked out when I have that done. Thanks JT!

trbo2nr

Yeah I noticed it happening on mine for nearly two years....now it's just a pain listening to it. I have 60k on it right now but think it too started around 45k. Since I ride my bike to work, I've been trying to keep the miles on the car low..... off the subject but I ended up putting 2k miles on the bike in 5-6 weeks, miles I saved from the car.

HA! I have had this exact same issue for some time now. I also assumed it was something to do with the suspension and chalked it up to being lowered with the H&R springs. I also took it to the shop twice (warranty) to have them take a look and each time they replaced something new. Don't remember what exactly though.
I will have to have them look at the motor mounts next time I'm in there. Mine is the same noise but seems to only come from the passenger side front. Any size bump and right turns, big or small, seem to set it off. I have just over 50K on the clock....

I also have what appears to be a slightly leaky head gasket, also passenger side. Have them knock that out while I'm in there.

I had the same issue. My dealer replaced the Sway bar bushings under warranty, and it fixed the issue. They also said that their was a TSB out on those.

ScottW911

Same here, thrust arm bushings. Unfortunately, the sound is back and I'm out of warranty.

Chazz

Same noise here at 75k. Approx. how much to replace motor mounts?

trbo2nr

I pulled stuff off looking at this and does not appear to be the suspension. So, I'm with everyone else with the mounts- at least I want to check and replace. Looking into costs right now.

spr

It's the thrust arm bushings. Also have them swap out the arms as they bend! They replace them with 204 units now due to this issue.

jturkel

idk. i had those replaced and that didnt solve it for me.

for those of you who think it might be motor mounts are are interested in them, i have found the following. hope it helps:

Is that the same as the radius arm bushings? I had the radius arm bushings replaced last year- that wasn't cheap.

trbo2nr

It was the sway arm bushings- I think that's what the mechanic said. I trust them completely as he was the only person that figured out my last problem with the torque converter not properly engaging and fixed it. I go to Mar over in Manassas, VA. Great shop and people.

SilverBulletAMG

I wish that's all it was but mine have been replaced (both sides) and it's still doing it on the passenger side. My other thought is possibly the strut.

trbo2nr

Struts will cost....will you go with aftermarket?

SilverBulletAMG

If it actually was the strut that needed replaced, I would shop around of course but am open to whatever. I don't autox the car so I don't need anything super fancy in that regards. Would probably just go with whatever was the best deal and was at least as good as stock stuts.

trbo2nr

The sway arm bushings were the problem. I just got the car back and its nice and quiet.........
