Hi everyone - I've described a high-pitched squeal coming from the right front of my 04 CLK (320 with 17" wheels). As I posted earlier, I was low (or maybe dry) on power steering fluid and filled it up, but the squeak still persists. (fluid level is totally stable, I am checking it at every fillup) Dealer inspected everything and pronounced it fine, including the brake job done by an indy.

This is really beginning to irritate me, and I am thinking the following:

- PS pump got ran dry and is going to squeal forever until I replace ($$$)

- Air is STILL not bled from the power steering system (service advisor said it would take 35-40 miles, it has been several hundred mi.)

- right front wheel bearing is going out, but I've never had a wheel bearing make that kind of a shriek!

Any thoughts from the team? What am I not thinking of...?

Thanks in advance.

I'm suspecting either ur PS pump is about to shiet the bed...replacement parts aren't that expensive through parts.com and labour done at a independent shop.

Took her into the dealer today - and did a ride with a tech. Chances are it is a wheel bearing, but they're gonna check the steering too. The best news is that the CPO warranty is still in effect, and hopefully will cover all of this....

Good news, let us know how it turns out.

yeah i would like to know the results too since i bought a CPO with extended warranty. since we are on the topic of squealing from hell....my driver seat makes this weird noise everytime i am moving in my seat and as i accelerate and shift slightly in my seat while driving....it sounds like its coming from the bottom of the seat....any help?

mine was doing that as well.it can drive you crazy.lube the springs under the seat and clean and armorall the area around where the seat contacts the seat belt receiver.

mine were squeakin too and i thought my pads might be low...but the mechanic told me they are fine...arghh it makes the car sound cheap when it squeaks

I am so ferking pXXed...got the car back - they pronounced it fixed, because they found a rock in between the dust shield and one of the brake discs....but it isn't. Got the car back and the noise is still there....calling tomorrow. My guess is wheel bearing... They say no issues with PS.

Good news is that I have the Behr radiator. SA says fluid contamination issue is mostly with sedans, he's never seen it on a CLK or SLK.

Noise caused by oversized retaining clip on aftermarket brake pads - as installed by indy repair shop - the clips caused the intermittent noise. 4 days of downtime, and an extra $300 to resolve. Dealer (RAB Motors in San Rafael was amazing!) found the problem, and put the pads in for the cost of the exploratory labor and the pads themselves. I am working with the indy shop on a resolution and will post photos of the offending clips and an update on how this finally came out. needless to say, I am relieved, but frustrated and a bit peeved that it took this long to get straight - bottom line is to use OE brake parts - and work with a mech that uses REAL mercedes parts.

What brand were the aftermarket pads?

Kev - I don't know yet on the brand of the aftermarket pads. The dealer is saving them for me - and rest assured I am going to let the group know....
