vectra estate front suspension creak?

[bigsteve]

Hi all, i have an annoying problem when i drive over speed bumps there is a dreadful creak, almost plasticky in sound, it only happens when the car is driven over the bumps with both front wheels, if you drive over with just either the left or right wheel over the bump it is silent...i have changed the anti roll bar links recently as they were knocking, but this has got me totally lost, has anyone had similar probs? cheers.

Mine has started to do the same thing, and I think its the anti-roll bar bushes - I'm on my third set though!

First things first - has it got the spring seat mods? If you feel behind the front wheel, in the pan of the shock absorber, the bottom coil of the spring should have a rubber sleeve over it. If not, that's a cheap option...

Either that or engine mounts have been known to squeak...

The radiator mounts are known to squeak too.

that's what I meant...

Ive got the same problem as you bigsteve, aint got a clue where to start to eliminate. I thought it might be suspension as it only seems to happen when the suspension is compressed over any little bump.

I have this problem too, more of a problem after coming down over a speed bump, a real bad creaking crunching noise. Definitely not radiator mounts for me, they've been done. do know if I'm imagining it or not but may seem worse in the cold (could this help narrow the problem down any ) I shall watch this thread with great interest.

I'd say that as I have the spring seat mod and the rad mounts mod all done and its still doing it. Pretty sure its not the engine mounts. hth

My car 54 plate does exactly the same over speed bumps only, otherwise ok. Its like a creak type noise not a knock. Sounds Mcphearson strut related. Not having a look now in this weather, will have to wait till summertime!

Just to add to the fray, I came to the forum in search of answer for this exact problem, a cracking noise, and quite a loud one at that, coming from the front suspension over speed bumps, its worse coming off the speed bump. It only happens over speed bumps so until a resolution is found I suggest we ban speed bumps. Im writing to my MP!
