can the hub bearings be replaced, or is the hub bearing integral to the hub assembly

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Your question and then the statement you've written seem to differ. You are asking if the hub bearings can be replaced. Yes, the hub bearing can be pressed in -- and the hub does not have to be replaced, necessarily. However, if the hub is found too have damage or wear, then it too may be needed. This is something that must be assessed by a hands on inspection. Now the next part - suggesting right front is grinding and the "wheel bearing is good" -- how do you know it is good? Right front rotational noise may be coming from the wheel bearing for hub, the brake rotor and brake pads, or even tires that make noise. You could also get harmonic noise from the differential in the transaxle. But it's all guessing unless a hands on - ears on - inspection occurs.
