Low rumble above 35 mph, Motor mounts?

Low rumble above 35 mph, Motor mounts?
Recently, I'm getting a low rumble that becomes more pronounced at around 35+ MPH. Louder when faster. My mechanic said it's one or more of the motor and transmission mounts.
When I'm driving and I put the car in neutral and I rev or take the foot off the gas, the sound stays consistent with the speed. So it's not the engine or exhaust.
So before I chase down the mounts, could it be the output shaft of the transmission, axle assemblies or hub/bearing sets? Or anything else I've missed?
Thanks in advance!!

Good start to check! Thanks!
I'll take it on a cloverleaf where I can do 40+ and see if the rumble changes up.
I'll ask my mechanic which parts he used for the strut mounts and bearings!
Just know, they do sound much better but haven't stood the test of time and miles yet. I'm getting doubtful these days. LOL I've had the same experiences as you!
Thanks again!

Rumbling consistent with speed sounds like a wheel bearing possibly to me. Does it change at all when you turn the steering wheel? Turning should take pressure/weight off the inside wheel (left wheel when turning left and vice versa) and lessen the rumble from a bad bearing on that side. I doubt it's an axle unless if you've had them out recently and maybe it's not seated/mounted correctly.

Did it myself, used the hub/bearing assembly which makes it bolt-on. they are a bit expensive though.. I think I have seen here that others changed just the bearing and re-used the hub, not sure how to do that...
