Advice on a noise.....
 

Hi,
I have a strange noise a little like the sound of a bike free wheeling. It isn't loud and can only really be heard when passing solid objects. It happens when moving in gear or neutral and wether the clutch is depressed or not. It doesn't change speed with gear changes, it just gets faster as the car goes faster. It seems to sound louder while cornering. Now I have a couple of ideas such as possible wheel bearings, maybe thrust bearing or something more sinister with the gearbox itself but I haven't experienced this before so it is all just guess work. Any advice or ideas would be much appreciated, and yes I will take it to a mechanic but like to have an idea of what i am talking about before i get there.

​​​​​​​cheers, Ian

Any chance of getting a recording of it??

​​​​​​​To be honest, I dont think it is loud enough to get an audio clip as yet, I only get the sound bouncing back off solid objects and then it isn't clear enough for something like a smart phone to pick it up. I will have a go but i have my doubts it will work yet.

I had a similar noise last year. Turned out to be a stone trapped in the brakes...

I was about to say stone trapped in tyre.

I would cry with joy if it was just a stone!!

Check all your tread, sounds like stone to me or nail.

​​​​​​​Recently had 2 new front tyres so it isn't tyre related unfortunately.

Have you checked them all? And did the noise come after having tyres done? I've had stones in Tyres before and sounds like what your describing.

I do have a couple of stones stuck in the new tyres, picked some out a few days ago, but the sound was before they were replaced so I am 100% certain that it's not that.

​​​​​​​Having read a couple of other threads I suspect centre diff bearings perhaps but still not sure. The car is booked in for an inspection but hate going into a mechanic without a reasonable idea of what the issue is.

Mine was caliper seizing. Does your wheel turn freely when on a jack?

No real symptoms or issues in this area as far as I can tell, no brake judder or noises when off brake and nothing raised in the recent MOT as an advisory.
​​​​​​​Still worth a check though thanks.
