Dorman 630-051 Drive Axle Shaft Assembly - Rear Left

Rear Left Axle Shaft for Ford F-150

Dorman 630-051 is a drive axle shaft assembly for the rear left position on select Ford F-150 trucks. It replaces the factory axle design with an upgraded OE FIX layout that uses an externally threaded axle end and matching nut for a more secure hub connection.

Built for 2021-2025 Ford F-150 applications with the listed rear axle configurations, this assembly addresses a known failure point in the original design and supports a more durable repair for trucks used for towing or off-road driving.

Key Features

• Direct replacement drive axle shaft assembly for the rear left side
• Patent-pending OE FIX design eliminates the factory thin-walled internally threaded axle end
• Externally threaded male end with matching nut secures the axle to the hub
• Constructed from SAE 1541 material for performance-grade service
• Includes the axle shaft, spacer, and spindle nut needed for the repair
• Compatible with select Ford F-150 rear differential applications

Detailed Description

Dorman 630-051 is engineered for select Ford F-150 trucks where the original left rear hub-to-axle bolt can shear and create noise, handling changes, or brake drag symptoms. This assembly replaces the failure-prone factory connection with a revised axle end design that captures the hub more securely. It is a practical repair choice for 2021-2023 Ford F-150 models with a 3.55 axle ratio and 2024-2025 Ford F-150 models with a locking differential, rear left. For related applications, see Dorman 630-050 for the right rear side and Dorman 630-052 for both rear assemblies. This part cross-references no listed aftermarket numbers for the same application.

What It Helps Fix

• Sheared rear hub-to-axle bolt on the left rear side
• Brake drag caused by rotor movement against the hub
• Rattle from a broken bolt head trapped in the assembly
• Rear handling changes caused by axle connection failure
• Repeat dealership repairs tied to the original axle design

Installation Notes

Install on the rear left position only. Verify axle ratio or differential configuration before ordering: 2021-2023 Ford F-150 with 3.55 axle ratio, or 2024-2025 Ford F-150 with locking differential. Confirm spline count, shaft length, and hub interface match the vehicle before installation. Follow factory service procedures for axle removal, hub service, and final torque specifications.

Quality Assurance

Dorman designs this OE FIX axle assembly as an upgraded replacement for the original Ford rear axle design. The revised threaded connection is intended to provide a more secure hub-to-axle interface and a longer-lasting repair for the listed Ford F-150 applications.
