Detailed Description

This Dorman axle hub O-ring is made from NBR and shaped to match the original seal geometry, helping preserve the seal at the wheel hub and axle housing interface. It is a practical choice when servicing the axle assembly on Ford F-250 and Ford F-350 models, as well as applications that cross-reference to Mopar 68036474AA and Ford F81Z1001BA. The 926-555 O-ring is specified with a 4.109-inch inside diameter, 4.387-inch outside diameter, and 0.139-inch thickness for accurate sealing fit.

This part cross-references Ford F81Z1001BA and Mopar 68036474AA for the same application.

What It Helps Address

  • Gear oil seepage at the wheel hub or axle housing seal area
  • Loss of sealing integrity after axle service
  • Contamination entering the axle housing through a worn seal interface
  • Repeat service caused by a flattened, hardened, or damaged O-ring
  • Fitment issues when replacing an original axle shaft O-ring

Installation Notes and Tips

Replace the O-ring whenever the axle is serviced, and inspect the sealing surfaces for debris, scoring, or old seal residue before installation. Confirm the axle seal dimensions against the original part and verify application details for Ford F-250, Ford F-350, or other listed cross-reference vehicles before assembly. Part number 926-555 should be matched to the original OE-style seal location to ensure proper seating.
