Installation involves pressing the bearing onto the axle shaft and housing—a straightforward procedure when performed with proper tools and technique. This is a pair, so both sides can be serviced in a single purchase, ensuring balanced performance and eliminating the risk of mismatched bearing wear that degrades handling. Verify your vehicle's axle configuration and bearing bore dimensions before ordering to guarantee proper fit and safe operation.
