Dan the Gear Man® Tech Notes: Difficulty
Prep Jeep Applications Tech Service Bulletin Matching Parts Applications
Tech Note 1: DifficultyThis is one of the hardest seals to install without special tools due to the restricted area it is in and the extremely tight fit of the seal. Get the TS4631 or TS4620 Tool Kit unless you really like cursing, wrecked seals, and tearing your axle down repeatedly for the same problem!
Tech Note 2: PrepOnce 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 3: Jeep ApplicationsOn 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 axles that use QU40105 was on early production XJs and YJs with axle Bill of Material number 610175 (XJ) or 610259 (YJ). All other 1987 Jeep Dana 30 CAD axles have the smaller Seal included in QK4624 Kit. If you have a 1987 XJ or YJ, 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.
