Hi, I just purchased a 1999 C280 Sedan with 84,000 miles. It handles like new and rides good on the usual road. The other day I drove over a brick street at about 15 mph and heard little noise from the front suspension. It sounds like shock bushings, track bar bushings, or shock problems. We have replaced most of these things and checked the others and evenreplaced lower ball joints and the noise is still there. We have no other thoughts on this at this point and could really use some help. We checked the wheel hub slackness, checked to see if there is any old collision damage, checked all we know how to do. Please help me. John
