Side Differential Oil Seal for Rear Axle ?

This precision side seal keeps gear oil inside the final drive and away from your brakes and road dust. It protects bearings and gears, keeping the differential quiet, cool, and long‑lasting. Built with heat‑resistant elastomer and a springed lip, it offers factory‑tight sealing in daily driving and towing.

Why you need it ?️

Without a healthy seal, oil escapes, lubrication drops, and metal parts run dry. A fresh seal prevents leaks, odor, and costly differential damage.

How it works ⚙️

An elastomer lip hugs the axle shaft while a garter spring maintains radial pressure. Micro ribs return oil inward as the shaft spins, handling heat, splash pressure, and axle movement.

When it fails ❗

• Wet differential side and oil drips ?
• Growl or whine on cruise/accel
• Premature bearing and gear wear
• Contaminated brakes and CV boots
• Risk of full differential failure

Replacement tips ?

• Inspect axle surface; polish any groove
• Lightly oil the lip; seat squarely
• Use correct driver; avoid cocking
• Verify breather is clear; refill with spec oil
