Drive Pinion Oil Seal for Differential ?️

Keep the final drive tight and quiet with this OEM-grade drive pinion oil seal. It stops gear oil at the spinning yoke, so bearings stay lubricated and the ring‑and‑pinion run cool. Built to exact Nissan dimensions, it restores factory fit and long leak protection for the rear differential.

Why this part is needed

When the old seal hardens, oil creeps out, coating the underbody and dropping level. Low oil brings howl on accel, extra heat, and fast gear wear. A fresh differential pinion seal prevents gear oil leaks, protects bearings, and keeps AWD performance smooth ?.

How it works

A heat‑resistant elastomer lip and garter spring hug the yoke. Micro ribs pump oil inward, while the steel shell presses into the housing. With a light oil film, the lip rides the polished surface and flexes with heat and slight runout, holding pressure at speed ?.

What happens if it’s broken

Typical signs: wet flange, burnt‑oil smell, drips near the prop shaft, humming or whine. Ignored, bearings run dry, teeth chip, and the differential can overheat or seize ⚠️.

Service notes

Inspect the yoke for a groove; fit a repair sleeve if scored. Set pinion preload to spec when tightening the nut. Clean the bore, use a thin sealant on the OD, oil the lip with 75W‑90, and clear the breather ?️.
