Fitment Notes

2024–2026 Wrangler JL – Direct replacement for applicable factory-equipped Dana 44 HD Full-Float rear axle applications, including Rubicon-series models where originally equipped.

2018–2023 Wrangler JL – Compatible when the vehicle has been upgraded or converted to the corresponding Dana 44 Full-Float rear axle configuration. This is not a direct replacement for the original semi-floating rear axle used on standard 2018–2023 JL applications.

Premium Wheel Studs – High-strength M14 x 1.5 wheel studs provide secure wheel retention and OE-style installation.

Description

The Axiom Supply Rear Wheel Bearing & Hub Assembly is engineered for Jeep Wrangler JL applications utilizing the heavy-duty Dana 44 Full-Float rear axle system.

Unlike a traditional semi-floating rear axle, the full-float design allows the hub and spindle to support the vehicle's weight while the axle shaft primarily transfers drivetrain torque. This creates a stronger, more serviceable axle configuration ideally suited for oversized tires, demanding trails, increased vehicle weight, and hard off-road use.

Axiom Supply's heavy-duty hub assembly incorporates premium tapered roller bearings and a robust hub structure engineered to minimize movement and maintain consistent wheel support under load.

The result is improved durability, dependable wheel stability, and long service life whether your Wrangler is navigating technical trails, running oversized tires, towing, or simply needs a premium replacement for the factory full-float hub.

For earlier JL vehicles, this hub is also an excellent solution for builds utilizing an applicable Dana 44 Full-Float axle conversion.

Includes

(1) Rear Wheel Bearing & Hub Assembly, Wheel Studs Installed, plus nuts and O-ring.

Fits Driver or Passenger Side

Installation

Designed for the Dana 44 Full-Float rear axle configuration.
