QU40105 Inner Axle Shaft Seal for CAD Axles Genuine original equipment seal fits most Dodge and Plymouth full-size 4x4's equipped with Dana-Spicer front axles and vacuum controlled Central Axle Disconnect (CAD) systems and 1984-1987.5 XJ or 1986 YJ Dana 30 Jeep with CAD. This seal is located inside your axle tube, just outboard of the CAD opening in your axle. This seal is installed from inside the CAD opening with QT1002 Installer and the rest of the tooling in TS4631 or TS4620 CAD Axle Seal Installer Kits. Imported.
Once the axle is disassembled, the old seals can be easily removed with our TS4861 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.
On Jeeps, QU40105 ONLY works on 1984-1987.5 XJ or 1986 YJ models with CAD. These early production CAD axles use QU40105 Seal which has a larger diameter. All 1984-1986 Jeep CAD axles use QU40105 Seal. The only 1987 axle that used QU40105 was on early production XJs with axle Bill of Material number 610175. 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.
