Dorman 926-129 Rear Axle Shaft Seal

Dorman 926-129 is a rear drive axle shaft seal for specific Ford Transit vans with Single Rear Wheel (SRW) rear configurations. It seals the rear axle to the wheel hub and helps address axle fluid leakage at the hub area.

Key Features

  • Drive axle shaft O-ring seal for the rear hub area
  • NBR construction with a black finish
  • Specific fit for confirmed Ford Transit rear applications
  • Compression seal design with round rim shape
  • Inside diameter: 95 mm; outside diameter: 102 mm; thickness: 3.5 mm
  • Direct replacement for OE reference BK3Z4A332A

Detailed Description

This Dorman axle shaft seal is built for rear axle sealing at the wheel hub on Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD models equipped with Single Rear Wheel (SRW) rear setups. The NBR material and compression-style design support a tight seal where axle fluid can escape if the original o-ring wears, hardens, or deforms. If you are searching for a rear axle shaft seal for a 2015-2023 Ford Transit-150 SRW or a 2021-2023 Ford Transit-350 HD SRW, Dorman 926-129 is the direct-fit service part to compare against the OE number BK3Z4A332A.

This part cross-references BK3Z4A332A for the same application.

What It Helps Address

  • Axle fluid leak around the wheel hub
  • Seepage from a worn rear axle shaft o-ring
  • Loss of sealing at the rear hub interface
  • Leak-related contamination around the hub area
  • Service replacement for damaged or aged axle seals

Installation Notes and Tips

Verify rear axle configuration before ordering. This seal is for rear applications on Ford Transit vehicles with Single Rear Wheel (SRW) equipment only. Confirm the hub and seal dimensions against the original part before installation, and inspect the sealing surfaces for wear, corrosion, or debris that could affect the seal. For search relevance, this part is commonly referenced for rear axle shaft seal replacement on Ford Transit-150, Ford Transit-250, and Ford Transit-350 service jobs.
