Help diagnosing a 'noise'

Recommended Posts

I had to drive into a car park who's entrance runs gently downhill. There are the inevitable speed bumps so I decided to coast down at walking speed. I noticed a "scuff, scuff, scuff" noise from the front of the car. Revving the engine didn't change it, or applying the brakes. Don't think I can hear it at speed? Car seems ok, no wheelbearing issues that I can tell.

Any ideas?

Could be a warped brake disc

you need to jack it up and spin each wheel round to try to narrow it down. if you use the standard car jack it might not create same effect as the weight won't be on the suspension.

The anti roll bar bushes probably need some grease on them.

The noise is 'rotational' ie in time with the wheels rotating

I tend to agree with you, but, would it quieten down when I apply the brakes? In my original post I noticed the noise when coasting down a long tarmac drive into a car park. I have to gently brake as the invevitable speed bumps arrive, the noise appears 'constant' whether I am braking or not?
