Wheel bearings are supposed to be occasionally maintained. Motor mounts never.

Motor mounts fail lots more often than wheel bearings.

Acknowledge that faulty previous maintenance of wheel bearings is possible.

I'll eat a crow when motor mounts make a whirring sound from the wheels on a turn. Wheel bearings can squeak, "whirr", rumble, scrape, you name the sound and they'll make it. Going around turns puts pressure on the bearings and stresses them. OP's brakes could be scraping as well.

You would notice a bad motor mount during idle when it is jerking back and forth.
