02 E320 4Matic, 45K mi.

Dealer replaced the ball joints (was surprised a car of this mileage would need that, but they insisted it did). Now I have a loud squeak occurring on left 90 degree turns - it happens near the point of maximum turn or at the beginning of straightening out. It could also be happening with right turns, but in my parking garage, where it's heard the best, it's all 90 degree left turns. Could squeak and ball joint R&R be related?

Also have another squeak - right front wheel area, frequency coincident with wheel rpm. I think it's brakes; sometimes the squeak stops when braking, and other times if it's not already squeaking I will get the same squeak when braking. It was only occassional before the ball joint replacement, immediately after that work it became pretty much constant.

Just trying to figure out what these might be and what to tell the dealer.

Thanks -
