Slow speed rubbing noise - similar to disc but not
Hi
Before I take it in for further diagnosis. My 2.0 C30 petrol 2012 is making a slight rubbing noise from front drivers wheel area. It is rotational noise and increases with speed. It does not go away with brakes applied and also exists when coasting in neutral (new Bosch discs and pads last summer) Checked for debris with disc and back plate and seems fine. The tyre could possibly be making the noise, but have my doubts as I can't imaging how it could make a kinda fff.......fff.......fff........fff........fff..... ..fff........fff sound. The car at speed is fine and no bearing failure noise when turning and no constant wirring hum. Could be a drive shaft issue I suppose but maybe that would make noise at speed as well. I could take caliper and disc off to check for deep debris that might be rubbing. But otherwise it's beyond me. Any ideas? Many thanks |

You seem to have checked the obvious. I would jack the car up and rotate the wheels by hand and listen carefully to see if you can pinpoint the noise. It's nearly always some debris, often a small stone, trapped between backplate and disc and easily overlooked. Flaking on a brake pad can also do it as can a rusty backplate which is disintegrating.

Thanks for reply, had that issue some time again before new discs and pads. Stone in the backplate.. Pretty sure this is not it.
Just popped out to the car and wiggled the front wheel.....it has slight front and back play (rotational and not in and out play) and not like the the passenger side . It might possibly be a bearing or tie rods,driveshaft or something else. I belive there shouldnt be any front to back play at all. It is only very slight. Will either take wheel off for closer look or just bite the bullet and drop off at usual garage. Last edited by chandra; Jul 27th, 2021 at 14:39. |

Sounds like a noisy wheel bearing. There may be no play in it though, but it could be causing the noise.
Jack the car up, put it in neutral & rotate the wheels by hand. Hold your hand on the spring & you should feel very little vibration. If you feel rubbing of any sort, that indicates a bad bearing. You could also have warped brake discs. Mine were “new” & still are in essence, as they were only fitted around two years ago with minimal miles done because of lockdowns. They’re already warped & I haven’t done any hard braking! This has been confirmed by a garage.
