Tech Note 1: Must Remove
Your brakes, wheel hubs, axle shafts, and differential must be removed from the housing to replace your QU40244 Inner Axle Shaft Seals. For Ford 1999-2004 Super Duty®, please refer to these 4x4 Tech Publications for service procedures:
TSB4643 Includes 5 pages of Step-by-Step procedures with 17 full-color photographs. Covers axle shaft removal, inner axle seal replacement, axle shaft reassembly, differential oil specs, differential gear backlash, torque specs and wrench sizes for fasteners. Explains in text and photos how to change the Inner Axle Shaft Oil Seals located next to the differential. Includes detailed axle shaft oil seal replacement procedures, tool recommendations, and torque specifications that you need to correctly perform inner seal replacement plus check the gear backlash on your Ford Excursion or 1999-2004 Ford F250, F350, F450, or F550 Super Duty® 4x4 Dana Spicer Model 50 or Model 60 front axle. *Note: The TSB4643 only applies specifically to Ford Excursion and 1999-2004 Super Duty®. For 2005 and newer Super Duty trucks, Inner Seal Replacement is identical. The disassembly and reassembly are different as far as the hub and rotors.
TM4637 Front Axle Tech Manual for Ford Excursion and 1999-2004 Super Duty is a 17 page, color illustrated, step-by-step printed shop repair manual that includes our four Tech Service Bulletins plus Front Axle Exploded Views. TM4637 covers: Front Hub Service (TSB4594), Axle Shaft Service (TSB4610), Ball Joint Service (TSB4591), and Inner Axle Seal Replacement Service (TSB4643), including torque specs all in one manual.
TM4688 4x4 Hub, Axle Shaft, Ball Joint, and Axle Shaft Seal Service Manual includes 76 full color printed tech pages with precise and detailed service instructions, plus a color photo for every step. (Includes all info in TM4637.) Close to 400 color photographs, color Exploded Views and Parts Guide. Comprehensive service information for replacing Front Axle Shaft Oil Seals, Axle Universal Joints, Ball Joints, Knuckle Seals, Axle Shaft Needle Bearings, Wheel Hubs, and Hub locks. Also covers basic Front Brake Service. Additionally includes complete torque specs, and tool recommendations.

Tech Note 2: QK4644 Seal Kit
If you already have the Ford QK4644 Seal Kit to service the Dana 60 axles, all you need to be able to service the Ford Dana 50 axles is this additional QT1129 Dana 50 Thrust Plate.

Tech Note 3: Component Tool
QT1129 Dana 50 Thrust Plate is a component tool of QK4643, TS4643, QK4808, TS4808, QK4982, and TS4982 Kits.

Tech Note 4: Seal Remover Tool
Once the axle is disassembled, the old seals can be easily removed with our QK4647 Seal Remover Tool Set or another suitable tool such as a length of sturdy pipe that will fit inside the axle tube and oil guide. You will also need to clean the inside of the axle tube to remove dirt and crud that could get pushed into your new seal during reassembly. For 1999-2004 vehicles, QK4647 is made it fit through QU20039 Plastic Axle Shaft Guides which are located in the axle tubes just outboard of the inner axle shaft oil seals.

Tech Note 5: When Replacing
When replacing your inner axle seals, ALWAYS inspect your Ball Joints, Axle Universal Joints, Differential Bearings, Outer Axle Shaft Support Bearing, and Wheel Hubs for wear or damage. The extra time needed to replace these components is minimal since you already have the axle apart to do the axle seals. Also, the large diameter seals on each outer axle shaft are not reusable and must be replaced with a new one using a special tool to prevent water infiltration and/or vacuum loss.

Tech Note 6: 4x4 Tech Publications
QU40244 is item 35 in the Differential Parts Full Color Exploded View that is included in these 4x4 Tech Publications for Ford Excursion and 1999-2004 Super Duty®: TM4637, and TM4688.

Tech Note 7: Effective with 2011 Model Year
Effective with the 2011 model year, Ford replaced QU40244 Inner Axle Shaft Seal, and which features an integral oil slinger on the diff side plus a generous axle shaft guide on the outboard side with QU20463 Seal that has no slinger and only a small shaft guide. Functionally, the seals are interchangeable on 1999 to current Ford Dana 50, Dana 60, and Dana Super 60 front axles, but they do require different installers. Personally, I prefer the earlier QU40244 Seal, but they are both high-quality oil bath seals that will keep oil in your diff for years if properly installed.

If you would prefer QU20463 Seal, the correct Installer is QT1222 which is available separately or in these Tool Sets and Kits for Ford:
TS4982 Tool Only Set for 1999-2005 Dana 50
