I've removed the bearings in mine, but I have a bearing puller and I had a stock of replacement bearings. Once you pull a cartridge bearing you should not reuse it. So, if your comfortable with r&r bearings then yes you could check it out. The non drive side bearing is what you want to pull if you decide to potentially kill your PT by doing so. There's a tube in there with a magnet taped to the drive side. The tube should be held in place by the inner races of the drive / non drive hub bearings. Even giving the NDS bearing a love tap on the outer races with a proper size socket and hammer may be enough to secure the tube if that's the problem. I doubt the magnet would un tape itself.
