If the front wheel bearings were loose / had play, they needed adjustment. I'm used to them requiring a torque-setting, but haven't done Mercedes wheel bearings so that's not my area (yet).

As far as brake squeal, you say you have "had the brakes done", what was done?

If there is a squeak, it might be the pads you're using. It can also be the rotor surface, you can go in and rough them up a bit with 600grit paper and brake the glaze on the rotors, that might help also. Another thing I used to do with fair-weather cars is to spray some water on the (cold) rotors and let them sit overnight, the slight rust would break up the smooth surface.

There's an old saying: "Germans don't care if the brakes squeak, as long as they stop the car. Americans don't care if the brakes don't stop the car, as long as they don't squeak."
