Tech Note 1: Seals
TS4808 Inner Axle Seal Tool Set with Depth Stop installs optional QU40244 seals. TS4808 Kit includes: QT1127 Seal Installer, QT1129 Axle Thrust Plate, and QTA1133 Press Screw Assembly. CNC Precision Machined Depth Controlled Seal Installer that stops at the original precise depth. *See Tech Note 3 below!
Tech Note 2: 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.
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 3: Installer Tool
TS4808 uses QT1127 Model 50 specific Fixed Depth Seal Installer which has a raised flange on it that will stop against the axle bore face when the seal is at the correct depth. This is a more fool-proof setup than TS4643, but it's more expensive and you cannot use this Installer on a Model 60 axle. Choose TS4808 for simpler and even quicker installation for your Dana 50 axle!
Tech Note 4: Seal Remover
Once the axle is disassembled, the old seals can be easily removed with our QK4647 Seal Remover Tool Set or other 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. QK4647 is made to 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 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.)
Tech Note 6: Effective with 2011 Model Year
Effective with the 2011 model year, Ford replaced QU40244 Inner Axle Shaft Seal supplied in the Kits on this page, 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, but more expensive 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
QK4982 Inner Axle Seal and Tool Set for 1999-2005 Dana 50
TS4983 Tool Only Set for 1978-current Dana 60, Dana Super 60

TS4808
Easy to use and made super-quick work of installing shaft seals! Great company too - I ordered the TS4807 by mistake. Didn't figure it out until I tried to use it, but Torque King was easy to work with to get it returned.

DANA 50 seal installer
Worked great, put them in once before , didn’t realize there was a set depth when you install them, they leaked, so I decided to get the right tool . Took longer to get the carrier out than it took to install the seals .
-
TS4808
Quality machined tool. Gave me a good peace of mind to know the oil seal was seated to the correct depth. 5 minutes to instal both sides. Tech support before buying the tool was top notch! -Dave

Dana 50 inner seal Guide Fixed Depth
Worked perfectly. Very expensive for a 1 time use tool but I wouldn't want to do the project without it. If something happens to the seals on installation you probably wouldn't know until a week later when they start leaking again and who the hell wants to redo all that work over $160? Not this guy!
