Detailed Description

Dorman 926-164 is a rear drive axle shaft seal O-ring used at the wheel hub to maintain the axle-to-hub seal on select Ford Super Duty trucks. When the original O-ring deteriorates, rear axle fluid can begin leaking around the wheel hub, creating a visible seep or drip at the axle end. This replacement seal is sized for specific applications and follows the listed dimensions for proper fitment.

This part cross-references Ford F81Z1001AA for the same application. It is a practical replacement for rear axle service on Ford F-250 Super Duty and Ford F-350 Super Duty models where the hub seal needs to be restored.

What It Helps Address

• Rear axle fluid leaking around the wheel hub
• Seepage at the axle-to-hub sealing surface
• Worn or flattened axle shaft O-ring material
• Seal deterioration from age and driveline heat exposure
• Loss of sealing integrity during rear axle service
