Rear Axle Shaft Assembly Kit

The bolt that secures the left rear hub to the axle on certain 2021-2025 Ford F-150 trucks equipped with the Max Tow package has been known to shear off, even after day-to-day driving, a modest number of towing trips or ventures off-road. Failure symptoms include the sound of brakes that are dragging (a result of the brake rotor moving freely against the hub), a rattle caused by the sheared bolt head trapped inside the assembly and in extreme cases, severe changes in truck handling. The dealer solution is to replace the axle assembly with the same original equipment design, inviting a future similar failure. This patent-pending Dorman OE FIX axle assembly eliminates the thin-walled internally-threaded axle end of the factory shaft design and the failure-prone bolt that connects it to the hub. Our upgraded axle shaft features an externally-threaded male end and matching nut to capture the axle end, resulting in a more secure connection between the hub and the axle. The entire assembly is designed for a straightforward installation and a longer-lasting repair that can prevent potentially dangerous vehicle control issues and multiple dealership repair visits that can keep a customer vehicle out of commission for several days. This kit contains the axle shaft, spacer and nut required to replace one left rear axle assembly. For the right rear axle version of this product, select Dorman part number 630-050. For our kit containing both assemblies, select Dorman part number 630-052.
