Common Problems This Bearing Can Address

• Rear wheel noise from a worn bearing assembly
• Excessive play or looseness at the rear hub
• Rough rotation caused by bearing wear
• Reduced rear-end stability from degraded bearing support
• Service replacement for a damaged or fatigued wheel bearing

Installation Notes and Tips

Verify the bearing dimensions, generation, and rear position before installation. Confirm the hub and mating surfaces are clean, and inspect related components for wear before reassembly. Because this is a non-driven, no-flange bearing, match the replacement to the original rear bearing configuration on the vehicle.
