Spicer Front Inner Axle Shaft Oil Seal Kit for 1994-2001 Dodge Ram 1500 & 2500 (Dana 44 with CAD, Pair)

Stop annoying front axle puddles, prevent gear oil from leaking out of your tubes, and protect your Central Axle Disconnect (CAD) system with this genuine Spicer Front Inner Axle Shaft Oil Seal Kit. Specifically packaged to service 1994–2001 Dodge Ram 1500 and Light-Duty 2500 4x4 trucks, this dual-side package replaces the highly specialized internal fluid barriers on vacuum-disconnect Dana 44 solid front axles.

Unlike standard solid front axles where both seals are pressed directly into the sides of the differential pumpkin, Dodge Ram CAD front axles utilize an offset sealing architecture. The driver-side seal is located next to the differential carrier, but the passenger-side seal lives deep inside the long right-hand axle tube, situated directly adjacent to the vacuum shift fork and sliding collar assembly. Over decades of service, heavy trail riding, or routine hub and U-joint maintenance, these seals naturally harden, crack, or get cut by the sharp splines of an axle shaft during re-insertion. When they fail, expensive differential fluid escapes into the tubes, starves the ring and pinion gears, and can pool inside the CAD disconnect box—wreaking havoc on your vacuum shift actuators.

This original equipment manufacturer (OEM) master service package supplies both the left-hand and right-hand factory-spec inner seals to overhaul the axle's primary fluid boundaries simultaneously. Sourcing genuine Spicer components guarantees the exact housing bore outer diameters, specialized multi-lip rubber durometers, and structural sealing geometry needed to keep high-viscosity gear oil trapped exactly where it belongs.
