Front suspension clunk

[jaff_fox]

Hi,
I have a Corsa B 1.5D (no anti roll bar).
The front suspension makes a slight, almost subconscious clunk sound when going over rough road surfaces at low speed. I can't tell from what side but its defiantly quite defined as the front.

I've changed all the ball joints and checked the obvious such as exhaust.
The noise can be stopped completely by deflating the tyres to around 15psi but obviously this is too low for the tyres. The noise is also worse when carrying a passanger.

The only other cause I can think of is wishbone bushes but they look fine.

Any help would be greatly appreciated!

Top shock mounts, bottom ball joints, track rod ends, tie rod arm bushs, gearbox mounts, engine mounts, lower arm bushs. Get a small pinch bar in all of those and see if you've got any movement.

it will more than likely be the top mounts m8 they always clunk as soon as they start to wear out

I know its been a while since this thread started but the noise still persists.

I did notice if the wheel tracking is incorrect the noise is less!

Is it common for top mounts to wear on these? I swapped the whole suspension with a donor car and still got the exact same noise which was very annoying. But is is possible the donor car had this problem if its common?

have you checked the tie bar bushes?
