05-15-5 LEAKS FROM REAR HALFSHAFT AXLE SEAL
Publication Date: July 13, 2005
FORD: 2002-2005 Explorer
2003-2005 Expedition
LINCOLN: 2003-2005 Aviator, Navigator
MERCURY: 2002-2005 Mountaineer
This article supersedes TSB 04-10-5 to update the vehicle lines, model years, Service Tips and labor operations.
ISSUE:
Some Expedition/Navigator vehicles built before 2/16/2005 and Explorer/Mountaineer, Aviator vehicles built before 3/18/2005, all equipped with the 8.8" or 9.75" ring gear and independent rear suspension (IRS), may exhibit leaks at the rear halfshaft axle seals. A new unitized seal is now available for service. The new seal design eliminates the need to use seal protectors during installation. Removal of the excluder seal (1L2W-1N013-BA) if present is required.
ACTION:
Order and install the new seal to correct leak condition. Review the Instruction Sheet included in the kit and obtain the required tools before beginning repair. Refer also to the following installation Service Tips.
INSTALLATION SERVICE TIPS
Refer to Workshop Manual Section 205-05 for half shaft removal and installation.
Use only the proper seal installation tool, Rotunda tool (206-034).
Ensure the seal installation tool is clean and free of debris prior to inserting into new seal. Do not use a damaged seal installation tool exhibiting nicks, burrs, or sharp edges.
NOTE: THE USE OF SEAL PROTECTOR 1L2W-4N206-AA IS NO LONGER REQUIRED.
Do not tap directly on the back of the seal installation tool, always tap on the handle, per Instruction Sheet. Seal should be driven evenly into housing bore with only enough force to seat in the bore.
Before installing the halfshaft, verify that the inboard excluder seal (1L2W-1N013-BA) is not present on the halfshaft. If the excluder seal is present, follow the kit Instruction Sheet and remove the excluder seal.
NOTE: OVERFILLING THE AXLE CAN INCREASE POTENTIAL FOR LEAKS. LUBRICANT SPECIFICATIONS CAN BE FOUND IN THE WORKSHOP MANUAL.
