2003 c240 4matic wagon
03 c240 4matic wagon grinding noise when turning left
car grinds when turning left noise matches speed of car like grind, quite grind, quite ect its not a constant grind but has gaps depending on speed. it sounds like a caliper backing plate doing it for a while now
here is whats been done
rear pads and rotors noise stilll there
front axelshafts/cv joints both sides noise still there
RR wheel bearing
now the front pads have like 3mm before they hit the sensor I do plan on replaceing them in ther next few weeks (pads and rotors)
the noise remains even when i brake and turn I have inspected the front end and cant see anything thats been rubbing front wheel bearings seem ok
only when turning left and very little when turning right and NO sound when straight
so any ideas???

It sounds like a front wheel bearing. You know your CV joints are OK
Do your front tyres show signs of feathering & cupping? Are they Conti SC2 or 3. They can do this.

Hmm - a bearing can still be noisy without play (yet) on a 4Matic. It could be those tyres. My Contis did exactly what you explain which is why I chucked the crap off at 15,000Km only partially worn. My noise tendency was opposite to yours which figures because we drive on the other side of the road & the road camber is opposite to yours. No other ideas unless it's brakes but I would then expect some noticeable play in a wheel bearing.
