My 1.0 Suzuki Swift has been knocking on and off for the last 2 years. Its gone through 2 mot's in its current state and can often be fine for months at a time but for the last couple of months its doing it all the time.
Basically every time i go over a bump and the car lifts up, the rear nearside suspension clunks. If i press down on the rear bumper and lift it up I can reliably get it to clunk every time the car is on its way up. The noise appears to be coming from the spring but the spring iteslf looks fine.
I'm going to investigate the problem tomorrow but i'm intersted if anyone had any idea's whats wrong or maybe has seen the problem before.
Many thanks
