knocking noise

[biggs001]

ive got a knocking sound coming from my car. it happens when im on a rough road. motorways its perfect no noises whatsoever. i have taken it to two garages to have a look but they have found nothing wrong.
maybe some one would know what i could be. maybe its something common. hope to here a reply. thanks

I had the control arm ball joints wear on mine which gave a knocking noise over rough surfaces.
Can be tricky to see/feel any play in the bj if vehicle is jacked up.
How many miles does your car have and when were thw control arms last replaced?

I had the very same problem and it was as mentioned above - the control arms. Can't quite remember how much they were? Around £30 each? No doubt someone will be along soon to confirm...

Had more than half mine away before so I bought the kit to replace them all. Think it was only £220.

Prices vary but it is advisable to buy quality parts as the cheaper ones have been known to fail again in a matter of months.
Lemfoerder/meyle & febi are good brands to go for.
