9031393011 Toyota SEAL, DUST (FOR FRONT AXLE HUB), RH/LH, Price: 42.79$, Weight: 0.124kg

Front axle hub dust seal for Toyota — fits RH/LH

This small ring keeps your front wheel bearings and hub internals safe. It blocks water, mud, and road grit, and holds grease where it belongs. Built with a steel core and oil‑resistant rubber, it shields the hub, CV joint, and ABS area so your front end runs quiet and smooth.

Why you need it ️

Daily rain, off‑road splashes, and winter salt try to invade the hub. A quality front hub dust seal prevents contamination, slows corrosion, and helps bearings keep correct preload. It also reduces wear on the spindle and protects the encoder or tone ring.

How it works

Pressed into the knuckle or hub, the seal’s lip rides on the inner race or stub axle. A spring on the main lip maintains even contact while the wheel turns. A secondary dust lip and a small labyrinth groove add extra defense, keeping grease in and dirt out.

When it fails ⚠️

Look for grease on the back of the wheel, humming or rumble that rises with speed, early bearing play, or an ABS warning from a dirty ring. Ignoring it can lead to overheating, seized bearings, CV joint damage, brake drag, and costly hub replacement.

Replacement tips ✅

Change both sides if wear is similar. Clean and lightly polish the sealing surface. Lubricate the lip with wheel‑bearing grease. Drive the seal square with a proper installer—never pry or hammer the edge. After assembly, torque the hub nut to spec and check for smooth, free rotation.
