Axiom Supply Bearing Spindle O-Ring — GM HD Truck 2500/3500 SKU: AX568346

Overview

This is a direct-replacement inner spindle O-ring from Axiom Supply for GM HD truck front wheel bearings — a small seal that protects the wheel bearing and axle from corrosion and contamination. It's a factory-equivalent replacement recommended with every wheel bearing service across a wide range of Chevrolet, GMC, and Hummer H2 trucks and SUVs.

Before ordering: Verified fitment spans multiple model lines with different year ranges — confirm your exact make, model, and year against the Verified Fitment table before ordering. Use one O-ring per side, per bearing — order the quantity your job requires.

Required separately: This is a single O-ring only. Wheel bearing hardware, grease, and any other components needed for a complete bearing service are not included.

Component Specifications

What Is and Is NOT Included

Included:

• (1) Axiom Inner Spindle O-Ring, part number AX568346

Not included:

• Additional O-rings (order 1 per side, per bearing — 2 total for a standard front axle service unless your application differs)
• Wheel bearing itself
• Grease or other service consumables
• Other wheel bearing service hardware

Critical Compatibility

• Direct factory replacement: Designed as a direct replacement for the GM factory spindle O-ring — not a universal or aftermarket-only fitment.
• Replace at every bearing service: Axiom recommends replacing this O-ring whenever the wheel bearing is serviced or changed, regardless of the O-ring's apparent condition.
• Quantity: Use 1 per side, per bearing. A standard front axle service typically requires 2 (one per side) — order accordingly.
• Multi-make coverage: Verified across Chevrolet, GMC, and Hummer H2 applications built on shared GM platforms. Confirm your specific make/model/year against the table rather than assuming cross-make interchangeability beyond what's listed.

Installation Notes

No detailed manufacturer installation instructions were supplied for this task beyond the following: lightly grease the O-ring before installation. This is a simple, accessible component typically replaced during routine wheel bearing service. Follow current manufacturer procedures for your specific wheel bearing service, including proper seating of the O-ring, before returning the vehicle to service.

The Obsidian Take

The AX568346 is a small but important part of any front wheel bearing service on this wide range of GM HD trucks and SUVs — a factory-equivalent spindle O-ring that protects the bearing and axle from corrosion, sold individually and installed with a light coat of grease. The main things to confirm before ordering are your exact make/model/year against the table and how many you need — one per side, per bearing.

This Product Is For You If

• You own a Chevrolet, GMC, or Hummer H2 model whose exact make, model, and year appears in the Verified Fitment table.
• You are servicing or replacing a front wheel bearing and need the corresponding spindle O-ring.
• You understand you'll need one O-ring per side, per bearing, and are ordering the correct quantity.

This Product Is Not For You If

• Your vehicle's make, model, or year is not confirmed in the Verified Fitment table.
• You need more than one O-ring and have not ordered the correct quantity for your job.
• You are looking for the wheel bearing itself, grease, or other service hardware — none of that is included with this listing.
