Bang!

[dellert 0]

I have a funny noise on my car. It is some kind of bush or rubber mount that is nackered, but where to start looking. It is very intermittent, only happens if I go over speed humps too fast or a very particular kind of bump in the road. It is quite noticeable, you can even feel it knock through the bottom of the car if you put your hand on it. Any ideas, it been doing it for a year, but not really got any worse. Thanks.

exhaust-related maybe? depends how big the bang is, all i can say is i had something similar on mine for a while, it was due to the exhaust sleeve being in the wrong position, so when i went over speedbumps it banged against the strut, i could feel it through the floor of the car too. only did it on speedbumps or really bad potholes though. took me a couple of months to work that one out!

It might well be that. What do you mean by exhaust sleeve? I checked all the little rubber banjo mounts, they all seem ok.

Is it coming from the front of the car?

If so then check your top suspension mounts(the rubber ones).Mine had a knocking noise over bumps so tonight ive changed these(old ones were knackered when i got them off) and it's like driving a new car :-)so much quieter!

Its really hard to tell where its coming from, I think it is coming from underneath, or the back. I think it is unlikely it would be anything on the front suspension as it runs and stops perfectly straight, there is no pull in either direction, generally even the slightest fault even a slightly odd tyre inflation results in a pull to the left or right.

What are the symtoms of the bushes on the beam axle failing, I have heard those mentioned more than once?

Thanks for your suggestions so far.
