Rear Axle Shaft Oil Seal for Nissan Utility Vehicles

This precision seal keeps differential oil inside the axle tube and blocks dust and water from entering. It protects wheel bearings and brakes, ensuring a quiet, cool, and clean driveline. Built with a steel-cased body, heat‑resistant elastomer, double-lip profile, and a garter spring, it grips the shaft while riding on a thin oil film for low friction and long life.

Why you need it

Good sealing stops leaks, maintains lubrication, and prevents contamination. It helps preserve bearing life, keeps the ABS tone ring clean, and avoids brake soak that reduces stopping power.

How it works ⚙️

The inner lip retains gear oil under rotation; the outer dust lip blocks grit. Spring tension maintains contact as the shaft flexes. Correct press-fit in the housing sets alignment, and a clear axle vent prevents pressure build‑up.

If it fails

Typical signs: wet backing plate, oil on the inner tire, burning smell, humming/whine. Driving like this risks bearing seizure, overheated brakes, and ring‑and‑pinion wear. Replace at first leak; clean the bore, polish the journal, and lightly oil the lip on install.
