Last saturday,I had tomount the spare on the rear passenger side because of a flat on the freeway. Now fast foward to this morning, had not moved the caruntil today.....I rotated the rotor and heard a noise andpin pointed to what I believeto be a bad bearing.The noise sound well like a bad bearing andis coming from in between the rotor and boot.

Not familiar at with mercedes, how difficult is it to remove the wheel bearing. Does the axle need to be removed, is the bearing pressed on or can it be accessed once therotor is removed? I did a search but couldn't really find and answer tomy questions, any help would greatly be appreciated. The carisa 04 C320 sport(automatic).
