I could be wrong ...again.... but I figure brake pads and wheel bearings very rarely would suddenly start making constant "loud high pitched squeal" noises, those usually build up a little at a time over time.

Did these noises just suddenly start happening when you went over the bump?

Did these noises actually just suddenly start happening when you went over the bump?

Since no noise when sitting idling and noise when you move, maybe something is rubbing an axle or wheel or something like that.
