that ol' knocking sound..

I'm sure this has been covered many times, but....knocking sound coming from under the car especially on rough surfaces. I've just had it back from my local (and very good) mechanic who has checked all the suspension joints and found them sound. He'd even bought wishbones in anticipation of the problem being there, but they were fine and so he's sent them back. So what is the problem? Any ideas much appreciated, thanks.

I have this problem, changed bottom arm, top arm drop links, and knocking still there, so I'm hoping its the arb, also there's mettle covers on the brakes this was loose on mine and causing a rattle sound.

Knocking sound from under gt

Hi, I had the same noise and it is a worn bush on the steering rack, problem is you cannot buy the bush on its own and im sure it would not cost more than a few quid but you apparently have to buy the whole rack around 180 then fitting on top, total i have been quoted 460.

Is it your exhaust banging on the floor? Check the rubber hangers are all present.
