Bumping noise whilst driving
#1

Hi,
I have a strange problem with my car. Thought I
would try and pick your brains before the
dealership (90GBP an hour here).
I have what can only be described as a bumping
noise when moving forwards, like what it would
sound like if you had something stuck in the tyre.
It seems to originate from the centre-front area
It starts at +20mph and the bumping increases in
frequency proportional to the vehicle speed.
Independent of engine speed or load.
Happens when the brakes are applied as well (i.e
it's not a warped disk)
Seems to get slighly louder on banked turns (left and right)
Occurs with the clutch in or out.
Occurs with the engine switched off.
So, I think it's somewhere in the transmission or
driveshafts&CVs ;-)
Any thoughts?
(I checked the tranny oil level and it was a little low but that's now been topped up and the
noise still persists)
Thanks,
Jon

But from the way you describe it...it sounds like the sort of thing that happens when you get snow on the inside of your wheels...but i doubt thats the case this time of year. Im assuming you already did a quick look over of all the components under the front of the car?

I didnt see it until I got it up on a lift. It was a good thing I found it when I did, because if it had burst, it would have been bad.......

later due to warranty lag. Could also be, any other rotating object on the car. It it a fast bump, slow bump, metal sound, rubber sound, loud, soft? Good Luck
