Service Your Wheel Hubs and Bearings
The INFINITI of South Bay parts team knows what it takes to keep your vehicle running great. Wheel hubs and bearings enable smooth wheel rotation while supporting your vehicle's weight and handling lateral forces during cornering. These precision-machined assemblies mount between the suspension and wheel, containing sealed bearings that reduce friction. Models like the INFINITI QX55 and Q60 depend on properly functioning wheel hubs and bearings for safe handling and quiet operation.
The Role of Wheel Hubs and Bearings
Wheel hubs provide the mounting surface for wheels and contain the bearing assembly that allows rotation. Ball or roller bearings sit in precisely machined races and separate the rotating hub from the stationary spindle or axle shaft. Modern sealed bearing units come pre-greased and require no maintenance during their service life. The hub assembly also includes mounting provisions for brake rotors and provisions for ABS wheel speed sensors. Bearing preload keeps internal components properly positioned to minimize play while allowing free rotation. These assemblies must withstand forces from weight, acceleration, braking, and cornering while maintaining precise alignment for proper brakes and suspension function.
What Damages Wheel Hubs and Bearings
Wheel hubs and bearings fail when seals deteriorate and allow water and contaminants to enter the bearing cavity. Lack of lubrication causes metal-to-metal contact that generates heat and accelerates wear. Impact damage from potholes or curb strikes creates stress cracks in the hub casting. Improper installation torque causes bearing preload problems that lead to premature failure. Corrosion on mounting surfaces creates play and vibration.
Timing Wheel Hub and Bearing Replacement
Replace wheel hubs and bearings when you hear grinding or humming noises that increase with vehicle speed. Excessive wheel play or looseness indicates bearing wear. ABS warning lights triggered by damaged wheel speed sensors often accompany bearing failure. Heat discoloration or grease leaking from the hub assembly signals imminent failure. Aftermarket wheel hubs and bearings often use inferior metallurgy and looser manufacturing tolerances that reduce service life and increase noise levels. Genuine INFINITI wheel hubs and bearings maintain factory specifications for fit, bearing preload, and durability. From accident repairs to custom modifications, INFINITI of South Bay has everything your project requires.
