QK4624 Front Axle Seal and Tool Kit for 1987-1996 Jeep XJ, YJ CAD Axles

QK4624 Inner Axle Shaft Seal Kit for Both Sides 1987-1996 Jeep Front Axles with vacuum controlled Central Axle Disconnect (CAD) on 1987.5-1991 Jeep Cherokee or Comanche (XJ) and 1987-1996 Wrangler (YJ) models. The passenger side axle shaft seals on these models are almost impossible to install without our installation tools. Our QK4624 Kit for both sides makes inner axle oil seal installation easy and almost fool-proof on your Jeep 4x4 equipped with the factory vacuum controlled Central Axle Disconnect (CAD) system. Our special, CNC Precision Machined, solid steel Seal Installers support these difficult to install seals in 3 locations so the seal cannot cock or get crushed during installation. If you need to replace your axle shaft seals, this is the way to go! Installers and Thrust Plate Made in Montana.

Tech Note 2: When Removing
Whenever you remove the front axle shafts on your Jeep, inspect the shafts and axle tubes for any signs of differential fluid leakage. It's a lot cheaper and easier to replace the seals than rebuilding your diff after it blows up due to oil starvation! Differential removal is required for the left (drivers) side seal, but not the disconnect (right) side on vacuum shift axles. These are tricky seals to install, but you can EASILY do it with one of these kits! QT1032 differential case spreader is definitely recommended but not absolutely required for differential removal/installation. Extra seals, differential cover gaskets, and RTV sealant are available separately.

Tech Note 3: Seal Installer Available
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. QT1080 Right Seal Installer will only work with original equipment design, NOK manufactured seals such as our QU40098. QT1089 Left Seal Installer will only work with original equipment design, NOK manufactured seals such as our QU40307. Seals manufactured by other seal manufacturers WILL NOT WORK WITH OUR INSTALLERS!!!! We do not manufacture installers for this application to fit any other competitive seal designs such as CR, National or NAK

Tech Note 4: Using Seal Installer
QT1080 and QT1089 Installers are Adjustable Depth type tools that allow you to offset the seals to a deeper depth to miss a groove or other damage on the 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 5: Axle Bill Of Material (BOM) Number
QK4624 Kit does not work on 1984-1987.5 XJ or early 1987 YJ models with CAD. These early production CAD axles use QU40105 Seal which has a larger diameter. All 1984-1986 Jeep XJ CAD axles use QU40105 Seal. The only 1987 XJ axle that used QU40105 was on early production XJs with axle Bill of Material number 610175. For the 1987 YJ, early production vehicles with BOM 610259 use QU40105 Seal, All other 1987 Jeep Dana 30 CAD axles have the smaller Seal included in QK4624 Kit. If you have a 1987 XJ, check the axle Bill of Material (BOM) number which is stamped on the front of the right axle tube next to the differential housing and also on a metal tag held on by the two farthest right differential cover bolts before ordering parts.

Tech Note 6: When Replacing
When replacing your inner axle seals, ALWAYS inspect your Ball Joints, Axle Universal Joints, Differential Bearings, and Wheel Bearings/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.

Tech Note 7: Seal Remover Tool Set Available
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.
