Hi All, I have developed a knocking noise form the rear of my car, its got worse since it came back from the mechanics today? I think it is coming from the rear passengers side wheel area but could also be coming from somewhere underneath the car centrally, these are the instances when I get it: 1. Whenever I go over small dips in the road at medium to high speeds. 2. When turning right quite hard forcing the weight of the car into that side 3. When breaking relativly hard in some circumstances It sounds like its coming from the hub area of the rear passengers side but not entirely sure, Any help very much appreciated, Thanks Ben.
