Are there over sized tires on the car? Might have loose wheel
well covering rubbing in the offending area. Other ideas are
brake pads may not be seating correctly in caliper and lug nuts
not torqued to spec. Warped or distorted brake rotors can have
issues as well. They need to be inspected/replaced depending
on run out. My first thoughts were CV joint but it looks like Benz
did a rear wheel design on this car. So if that is true the last idea
would be a bent spindle (hopefully not) or improper pre-load and
load spec to bearing (s). Only other thoughts are that for have
previously owning a benz that they are hard on the front end
components especially the lower ball joints. Just trying to cover
all the possible things here. Hope your shop and car treat you
well.
Good Luck!
