All 1 Known Issues
On the 1994-2009 Dodge Ram 3500, ram 3500 dually and single rear wheel trucks commonly develop rear axle seal leaks from the Dana 80 (1994-2002) or AAM 11.5 (2003-2009) rear axles. The axle shaft seals and pinion seal are the most common leak points. Leaking gear oil can contaminate the rear brake shoes/pads and cause brake fade. The heavy loads and towing duties of 3500 trucks accelerate seal wear. Oil found on the inside of rear wheels or dripping from the axle housing are the primary indicators.
Common Symptoms
- Gear oil visible on inside of rear wheels
- Oil dripping from rear axle housing
- Rear brakes contaminated with gear oil
- Reduced rear braking performance
- Low rear differential fluid level
How to Fix
Confirm the leak source by cleaning the axle housing, checking differential fluid level, and inspecting the axle shaft seals at the hubs and the pinion seal at the yoke; also inspect the axle vent tube, because a clogged vent can force gear oil past otherwise good seals. Repair typically involves removing the axle shafts and hubs to replace the inner/outer axle seals and any worn bearings on Dana 80 or AAM 11.5 axles, or removing the driveshaft and yoke to replace the pinion seal and reset pinion bearing preload if required; any brake shoes, pads, or rotors/drums soaked with gear oil should be replaced, not just cleaned. Refill with the correct gear oil (and limited-slip additive if equipped), verify no excessive axle shaft or pinion play, and road test for leaks. Typical cost is about $300-$700 for a single axle seal repair, $250-$500 for a pinion seal, and $700-$1,500+ if both sides, bearings, and contaminated brake components need replacement.
