it depends. when you talk to the parts guy, ask him if its a strut mount assembly with bearing plate or if you need a bearing plate separately. its that simple.
If you take apart your mount and you find that there is no problems with the bearing plate (problems would be binding or any kind of unusual noises like a grinding) then order a mount and not a bearing plate.
If you do order a new mount and the noise doesn't go away, i would suggest looking at the struts next. take a straight edge and hold it against the piston rod to verify that it is good and straight. Also, inspect the seal that the strut piston rod meets the strut housing for leaks or damage. It is normal to see a minor amount of oil around that seal, but if there is more than a minor amount and you see a coating of oil down the body of the strut then chances are that the strut is bad.
