Keeping your car well-maintained is a great way to protect your investment, as well as your safety on the road. Wheel hubs and bearings allow your wheels to rotate freely while supporting the vehicle's weight. The hub provides the mounting surface for wheels and brake components. Bearings contain precision steel balls or rollers that reduce friction between moving parts.

The Job These Components Perform

Wheel bearings sit inside the hub assembly and allow smooth rotation at any speed. They're packed with grease to minimize friction and heat buildup. The hub connects to your suspension components and provides the mounting points for brake rotors or drums. Nissan Maxima and Nissan Armada models use sealed bearing assemblies that combine the hub and bearing into one unit.

Why Hubs and Bearings Deteriorate

Bearings wear out gradually from millions of rotations over thousands of miles. Water contamination washes away protective grease and causes rust. Impact damage from potholes creates flat spots on bearing races. Improper installation torque can preload bearings incorrectly and accelerate wear. Aftermarket bearings often use lower-grade steel and inadequate seals that allow early contamination and failure.

Recognizing When Replacement Is Needed

Listen for growling, humming, or grinding noises that increase with vehicle speed. Excessive wheel play when rocked by hand indicates bearing looseness. Uneven tire wear on one side suggests alignment problems from worn bearings. Address these issues promptly since failed bearings can cause wheel separation. Genuine Nissan hubs and bearings meet exact factory specifications for bearing preload, seal design, and metallurgy.
