Yukon Gear Axle Seal For 9.5in GM is the exact Yukon Gear & Axle differential seal kits identified by manufacturer part number YMS3747. Match the part number, vehicle, axle housing, differential, spline count, gear ratio, carrier break, position, dimensions, and intended use before ordering.
Key Features
- The GM 9.5-inch differential uses 75W-90 GL-5 gear oil.
- An axle seal sits at the outer end of the axle tube, where the axle shaft exits the housing toward the wheel hub.
- Gear oil will appear on the inner face of the wheel or brake drum, often accompanied by a burnt gear oil smell from the brakes.
- You may also see a wet residue along the bottom of the axle tube near the wheel hub.
- The axle bearing and seal occupy the same location at the end of the axle tube, and accessing one requires the same disassembly as the other.
- If there is any roughness, play, or noise in the bearing, replacing it at the same time avoids returning to the job shortly after.
