Detailed Description

It is a steel replacement shaft with a 14 mm wheel stud thread diameter and 1.5 mm thread pitch, making it a practical solution when the original axle shaft is damaged or the bearings are worn. The assembly is intended for direct OE replacement use on 2015-2024 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD rear applications. This part cross-references Ford service numbers such as BC3Z1244A and CK4Z1239A for the same application.

What It Helps Repair

• Rear axle shaft damage from wear, impact, or overload
• Noise or vibration related to a worn axle shaft assembly
• Loss of wheel support caused by axle shaft or bearing-related failure
• Service issues on Ford Transit DRW rear axle assemblies
• Fitment problems when replacing an OE rear axle shaft on Transit vans

Installation Notes and Tips

Verify rear axle fitment by year, model, and dual rear wheel configuration before installation. Confirm the 180 mm wheel bolt pattern, 34-spline inboard configuration, and 14 mm x 1.5 mm wheel stud specification match the vehicle requirements. Because this assembly does not include an ABS tone ring, hub bearing, axle shaft seal, or brake hardware, reuse or source those components separately as needed for the repair.
