Rear Hub Grease Seal for Nissan SUV – Bearing Protection You Can Trust ️

This rear hub grease seal is a precision metal‑rubber ring that locks lubricant inside the hub while blocking water, dust, and road salt. It keeps the rear wheel bearing clean and packed, so your ride stays quiet, cool, and safe mile after mile.

Why you need it

The seal maintains a closed, greased environment around the bearing. Without a tight seal, grease escapes and contaminants enter, causing wear, heat, and noise. A healthy seal means longer bearing life, stable handling, and reliable brakes.

How it works ⚙️

Pressed into the hub, the metal case holds an elastomer lip with a spring. The lip rides on the axle journal, creating a constant radial contact. This lip keeps grease in and keeps grit out, even under heat, vibration, and wheel speed.

What happens if it’s broken ❗

Grease leaks onto the backing plate or rotor/drum, the bearing runs dry, and wear accelerates. You may get humming at speed, play in the wheel, extra heat, and in severe cases ABS issues or brake fade from contaminated friction surfaces. Left unchecked, it can damage the hub and axle seat.

Signs it’s time to replace

• Grease traces on inner wheel, backing plate, or brakes
• Growling or rumble that rises with speed
• Wheel play at 12–6 o’clock check
• Burnt grease smell after driving
