Wheel noise. bearing tyre?

[bodgit]

last week my car skidded into the kerb on ice. Smashed my alloy and bent the wishbone. I,ve had new alloys and the wishbone put on but Im getting an oscillating noise from the same corner.
The garage says the bearings are fine so Im just wondering if the impact may have damaged the tyre so as to make the noise. Its a dull low noise but very noticable. There's no vibration or pulling.
