Hi. Just a quick question. I have a 1989 300E and today it started making this noise on the front right wheel part. It's not exactly a rubbing sound, but sounds more like old unlubricated metal, kind of like an old door hinge. This sound eminates from the suspension portion only on the left side. I have checked and have no problems with lug clearance or tire rubbing in the past. I suspect that it is merely a joint that needs lubrication since the sound only occurs when I turn the wheel left or right. What shop can I go to fix this problem? Will a regular lube shop be able to handle it or will I have to go to my mechanic? Thanks alot.
