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.

Basically, the old axle seal was a 2 piece design. One piece sat on the inner cv joint housing (where it contacts the axle seal), and the other piece was the axle seal itself. The newest axle seal kit 7L1Z-4A109-D (02-07 explorers) is a one-piece seal and a new circlip (axle retaining clip). The update instructions say to do away with the seal that is pressed onto the cv joint housing, and just use the new 1-piece seal. It calls for some special tools, which amount to a 2.5 lb slide hammer attached to a bearing/seal puller, which is just a 3-jaw internal puller legs. You can pull the bearing and seal, or just the seal itself.

You are also supposed to use the new Lisle 17850 seal installer. It's basically a Ford seal driver with a really long hammer, that allows you to hammer it in from about 2 feet away, so you can clear the frame tube and all. It says not to tap on the seal or the seal driver itself, but to tap on the driver handle, to ensure an even seal installation. Then, you're supposed to check the gap between the seal flange and the rear end housing, to make sure that there is no more than a .010" gap all the way around. I guess in other words, make sure you tap it all the way in.

I bought an OTC slide hammer kit and a slide hammer extension and a cv fork (all OTC), to use instead of Ford's cv fork and driver/handle. Basically, Ford calls for pushing/hammering the cv joint out, while I'm trying to pull/slide hammer it out instead. If my slide hammer doesn't produce enough weight/action, then I may have to hammer it out from the other direction instead. Hope this helps someone.
