product note

For the 1994-1999 model years, Dodge Dana 44 and Dana 60 front axles with vacuum controlled Central Axle Disconnect (CAD) use the exact same inner axle shaft seals and seal installation tools. QK4620 and QK4631 will work on both Dodge Dana 44 and Dana 60 axles for these years.

tech note

Differential removal is NOT required to change the QU40105 Right Axle Shaft Seal as it is located in the right axle tube just to the right of the rectangular CAD opening. A complete axle teardown including differential removal is required to change the QU40159 Left Seal.

tech note

Successfully installing a CAD axle shaft seal without the correct Seal Installer has about the same chance of success as buying a winning lottery ticket. Makeshift methods don't usually get the job done due to the restricted area you need to work in and the amount of compression needed to be applied to the seal. Due to the way we have to make the Tool, your Seal Installer and Seal MUST match. QT1002 Right Seal Installer will only work with original equipment design, NOK manufactured seals such as our QU40105 (Dodge p/n 4506005). QT1029 Left Seal Installer will only work with original equipment design, NOK manufactured seals such as our QU40159 (Dodge p/n 4116366). Seals manufactured by other seal manufacturers WILL NOT WORK WITH OUR INSTALLERS!!!! If you have the green, CR manufactured QU40326 (Dodge p/n 4506005AB) Right Seal, use our QT1114 Installer. If you have the green, CR manufactured QU40270 Left Seal, use our QT1084 Installer. We do not manufacture installers for this application to fit any other competitive seal designs such as National or NAK.

tech note

We make two types of Seal Installers for your Ram 4x4: Adjustable Depth and Fixed Depth. The Kits on this page include Adjustable Depth Installers that allow you to offset the seal to a deeper depth to miss a groove or other damage on the axle shaft. These installers will work on both 1988 to 2001 Dana 44 and 1994 to 1999 Dana 60 axles. However, YOU MUST be careful you do not set the seal TOO DEEP which may place the seal beyond the axle shaft seal surface! Our Fixed Depth Installer Kits (QK4698 ) have Seal Installers that will firmly stop at a preset depth. Fixed Depth Installers will only fit Dana 60 axles in 1994 to 1999 Ram 2500 and Ram 3500 4x4s. Choose our Adjustable Depth Seal Installers for installing seals in any 1989-2001 Dodge with a Model 44, or if you want the flexibility to offset the seals on 1994 to 1999 3/4 ton and 1 tons with the Dana 60. Choose our Fixed Depth Installers if you want quick, fool-proof seal installation on 1994 to 1999 Dana 60 equipped Ram 2500 and Ram 3500.

tech note

Kit includes 1 seal for each side. Order extra seals if you believe Murphy's Law will strike-Anything that can go wrong will!!

Need Tech Help on how to perform Inner Axle Seal Replacement on your 1994-1999 Dodge Ram 2500 or Ram 3500? Get my TSB4620 Inner Axle Seal Replacement Tech Service Bulletin, a fully illustrated, 8 page publication with 31 color photos. Includes Step-by-Step Service Procedures, Tool Recommendations, and Torque Specifications in an easy to read and follow format for replacing those pesky front axle shaft seals on all 1994 to 1999 Dodge Ram 4x4 trucks with Dana-Spicer Model 60 front drive axles. Available in print version only!TSB4620 is specific to Dana 60 axles, but with the exception of a unitized hub/rotor and 4 bolt hub flange, the service procedures are also applicable to 1994-2001 Ram 1500 and 1994-1997 Ram 2500 4x4s with Dana 44 front axles.

tech note

Once the axle is disassembled, the old seals can be easily removed with our TS1184 Seal Remover Tool Set or other suitable tool such as a length of sturdy pipe that will fit inside the axle tube. 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.

tech note

When replacing your inner axle seals, ALWAYS inspect your Ball Joints, Axle Universal Joints, Differential Bearings, and Wheel Bearings/Hubs (also Spindle Bearings/Seals on 1988-1993) 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.
