QK4982 Dana 50 Adjustable Depth Inner Axle Seal and Tool Kit

QK4982 Dana 50 Adjustable Depth Inner Axle Seal Kit with 2nd design inner axle seals and adjustable depth installer tool set is made specifically to install the 2nd design seals in 1999-2005 Ford Excursion and 1999-2002 Ford Super Duty Dana 50 4x4 trucks. QK4982 will quickly and easily press in these new 2nd design Inner Axle Seals without damage because the installation tool cups the seal so force is only applied on the outer shell. The Seal Installer does not have a depth stop so you have to watch how deep you install the seal. *See Tech Note 6 Below.

QU20463 Seal can be used to replace QU40244 in 1999-2005 Ford Dana 50 axles with this Installer Kit.

For Ford Excursion and 1999-2004 Super Duty® trucks, we offer our optional, color illustrated, step-by-step Tech Service Bulletin TSB4643. See Tech Note 3 below. The seals & installer are different in this Tech Service Bulletin, but the procedures are the same.

Tech Note 3: 4x4 Tech Publications
Your brakes, wheel hubs, axle shafts, and differential must be removed from the housing to replace your original QU40244 Seals with QU20463 Inner Axle Shaft Seals. For Ford Excursion and 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.
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.

(Includes all info in TM4637.) Close to 400 color photographs, color Exploded Views, and Parts Guide.

Also covers basic Front Brake Service. Additionally includes complete torque specs, and tool recommendations.

Tech Note 4: Ford 2011 Model Year
Effective with the 2011 model year, Ford replaced the original QU40244 Inner Axle Shaft Seal 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 2004 Ford Dana 50. 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 QU40244 Seal, the correct Installer is QT1129 which is available separately or in these Tool Sets and Kits for Ford:
TS4643 Adjustable Depth Tool Set Only for 1999-2005 Dana 50
QK4643 Adjustable Depth Inner Axle Seal and Tool Set for 1999-2005 Dana 50
TS4808 Fixed Depth Tool Set Only for 1999-2005 Dana 50
QK4808 Fixed Depth Inner Axle Seal and Tool Set for 1999-2005 Dana 50

Tech Note 5: Seal Remover Tool Set
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 1999-2005 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 6: Installing Seal
Our Adjustable Depth QT1222 Installer Tool included in this Kit allows you to install either Axle Seal slightly offset of the original seat to miss grooves worn in your inner axle shaft. However, YOU MUST be careful you do not set the seal TOO DEEP which may place the seal beyond the axle shaft seal surface!

Tech Note 7: When Replacing Seals
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 5" diameter Seal on each outer axle shaft is not reusable and must be replaced with a new one using QT1515 special tool to prevent water infiltration and/or vacuum loss. (See QU40233 1999-2002 Seal, QU20035 2003-2005 Seal, and QT1515 Installer or Hub and Knuckle Seal Kits QK4610 1999-2002 or QK4846 2003-2005.)
