My truck rear axle seals leak when it’s cold and I live in Fairbanks Alaska (it’s cold 7 months a year). I’m on the 4th rear axle seal on the left side and 2nd seal on the right side. Replaced 2 times while under warranty and I’ve replaced 4. I can blow through the air vent hose and push a wire into the pumpkin so I think it’s not a vent problem. I replaced the fluid to an arctic lube. Any suggestions besides not to drive it in the winter?
