I just had a new lower control arm put on, and a new strut. Now i have a loud bobbling noise coming from that area. car handles just fine and corners just fine, but when i go over bumps and ride over rough surfaces, etc... there is this loud bobbling noise. Not sure what it is. It doesn't do it on smooth pavement. The noise wasn't there before nerw suspension parts where put on. Any idea what it could be making that noise?
