Hi guys, i seem to have acquired a knock from underneath the car (sounds like under driver seat) It only happens once when turning out the bottom of my road and when turning back into my road. It's a sharp corner on a hill so a lot of the weight transfers from one side to the other when turning in. It's quite a hard, deep sounding knock like something moving when turning it. I can't seem to make it knock anywhere else but there? I recently had the gearbox done so could it be anything that was not tightened up correctly? Any ideas? thanks
