Description

Overview

The Guardian HP drive axle hub seal protects heavy-duty wheel ends by retaining lubricant and excluding road contamination. Its semi-unitized construction installs directly on the axle, helping keep the sealing element aligned during hub installation.

Features

• High-performance HNBR-PTFE sealing lip for heat and contaminant resistance.
• Rubber outer diameter helps reduce corrosion damage around the hub bore.
• Semi-unitized design installs on the axle rather than into the hub bore.
• Drive-axle wheel seal configuration for heavy-duty wheel-end service.

Compatibility and Fitment

Match the removed seal to the drive-axle wheel end and compare the hub bore, spindle shoulder and seal width before ordering. Similar wheel seals can use different sealing dimensions even when the overall appearance is close.

These cross-references show where this part replaces the part numbers and applications listed. Some installations may need minor changes. 370003A, 380003A, 392-9131, 3929131, 393-0173, 3930173, 393-0273, 3930273, 47691, 47697, 10045887

Compliance and Safety

Remove burrs and clean the hub bore, spindle and wheel cavity before fitting. Install the Guardian HP seal onto the spindle, not into the hub bore, then lubricate the seal outer diameter before bringing the hub onto the spindle. Finish by checking bearing adjustment and lubricant level.

Trailer Applications

This seal suits heavy-duty drive-axle wheel ends where the removed seal matches the Guardian HP application and sealing dimensions.

Why Choose ICS Trailers

Drive-axle seals can look nearly identical while using different hub-bore and spindle-shoulder dimensions. If the old number is unreadable, ICS Trailers can compare seal photos, measurements and axle details to help narrow down the correct wheel-end replacement.

• Useful for matching the seal alongside bearings and other wheel-end service components.
• Cross-reference numbers can be compared against the removed seal when the original brand or number has changed.
