  • REAR AXLE LEAK – DANA S-110 REAR AXLE
Publication Date: June 3, 2005

FORD:
2005 F-450, F-550

ISSUE:

Some Super Duty F-450/550 vehicles equipped with the Dana S-110 rear axle built between 5/1/2004 and 2/28/2005 may exhibit a wheel seal leak. The leak typically occurs on the passenger side of the vehicle. Repairing these leaks using only a replacement seal may not ensure a lasting repair. A repair kit has been developed containing two (2) sleeves and seals, retaining compound, and an installation tool.

ACTION:

This repair is limited to axles built in Brazil manufactured between the dates listed above. Verify where and when the axle was built using the identification tags on the drive axle assembly (Figure 1). Check the stainless steel tag located on the arm of the axle housing to confirm where the axle was built. If it was built in Brazil, check the serial number on the carrier assembly identification tag. Serial numbers between HN01297868 and HN01775113 are the only ones affected by this TSB. If the axle was built in Brazil and falls in this serial number range, install the seal kit on both sides of the axle. One seal kit will service both sides. Refer to the following Service Procedure.

SERVICE PROCEDURE




Figure 1 – Article 05-12-4

NOTE:THE KIT CONTAINS A SPECIAL INSTALLATION TOOL THAT MUST BE USED DURING THIS REPAIR.

  1. Remove both rear wheels, hub assemblies and inner bearing cones.
  2. Discard the wheel oil seals.
  3. Clean any oil or contamination from the seal mounting surface of the hubs and the axle spindles.
  4. Apply a line of Loctite 680 to the spindle at the seal journal. It is important that the Loctite is applied around the entire circumference of the seal journal (Figures 2 and 3).
