Q: Rubbing noise coming from the front driver's side tire. What could be the problem?

When driving I keep hearing a sort of soft scrubbing noise coming from the driver's side front tire. Ive taken it to a local transmission shop and after driving it they said they didn't notice anything, but I am sure there is an issue in the works and I'm trying desperately to head it off. The tread on the tire looks fine, I know it's not scrubbing the wheel well, and it has brand new strut assemblies, including mounts, springs, and insulators, on the front end (the noise was there before replacing then with no change afterwards). The noise is noticeably louder when the tires have more pressure on them, like when going over a bump, but never gets so loud that it wouldn't be drowned out if the radio were cut on. The lower control arm needs bushings on that side but I've been told that shouldn't cause my issue and that I should be looking at the wheel bearing, CV axle, and transmission when trying to hunt down the problem. Is this true?
My car has an automatic transmission.
