Humming noise from wheel

[Lozw86]

Hi all,

I had an unfortunate sideways slide and collision with a kerb in the ice at around 15mph. There is a humming type noise coming from one of the wheels on the side that the impact occurred. I have had a full wheel alignment completed and the noise remains. Might the wheel bearing(s) be damaged? Any other likely causes of the noise? It's a 2017 BMW. Worth a trip to the dealer or get an independent to check it out?

Any help or suggestions appreciated

Thanks

Sounds like a bearing to me.

Get down to and indi, a quick ride along, or shake of the wheel, and the mechanic will know.

Bearing is unlikely, I would have thought.

Might be damage to the tyre carcass. Try changing to the spare tyre, if you have a full-sized spare.

Might also be a bent or buckled wheel, although I've have expected them to pick that up when they were doing the geo (though maybe not, with some of the monkeys they employ these days...), and you'd normally get feedback through the steering. Try spinning the wheel by hand (up on jack, of course) to see if it's visibly out of true.

Thanks for the replies

The wheel has been replaced for a brand new one ( the original was damaged in the collision ) so I know the wheel is true

That hopefully rules out damage to the tyre carcass, too, then.

It's not just 'feathering' of the new tyre, is it?

Some cars are probe to this, even if the geometry is correct (and possibly yours isn't, if it's just been re-done): I used to have a Skoda Octavia vRS that went through phases of it, depending on the level of tyre wear, and made the most godawful droning noise, just like a worn bearing.

No the existing tyre was examined (all ok) and fitted to the new wheel

I think it must be bearings or something else

A damaged wheel bearing would fit the symptoms. Assuming you take it to a mechanic to have it repaired, they would probably be able to confirm that diagnosis before you commit to the repair.

It’ll be the bearing.

Bearing damage is entirely likely from a sideways impact with something solid.
