Hi there, I am getting a major clunk under my car - it feels like it's coming from the driver's side firewall or around the gearbox tunnel. I have changed the engine mounts and the power steering rack bushes. Pedders tell me that it is a ball joint on the drivers side; though I am thinking that it is probably a gearbox mount. I have had a mechanic look at the gearbox mount who reckons mine is ok; can the gearbox mount be rooted if it isn't split etc? Thanks, Ben.
