When a wheel bearing fails, the most common symptom is a roaring noise that increases with vehicle speed. Most commonly we hear the roar from 15 through 50 MPH. The noise may not be noticeable at low speeds and may even go away at higher speeds. As the bearing gets worse, the roar will normally grow louder and more pronounced.
The balls in a wheel bearing are hardened steel. They roll in precision-machined grooves and held together by the axle shaft or a thread fastener. They do not design pressed-in bearings to be disassembled. Any force applied to the hub will dimple the bearing races, which results in premature failure. This type bearing is destroyed when removed, so no service is possible other than replacement. They are lubricated when assembled, and the lubricant lasts the life of the bearing. I would not mess around and replace the passenger side wheel hub.
good luck
