Noise Question

Hello,

Have a 1997 Buick LeSabre with 82K

Has recently developed what I would call a resonance when passing thru about

Calling it a resonance, as it seems to disappear at other speeds. Pretty much of a "whine"..

Car acts normally at other speeds.

Any thoughts what this might "possibly" be ?

Wheel bearing ? CV joint ? Or,... ?

Thanks, B.
