How much does it cost to fix a leaky axle on a 2001 Yukon?

it depends on where it is leaking from. if its leaking from the seal in the middle, or the "pumpkin" then it shouldn't be overly expensive. because you just have to drain it, replace the seal, put it back together an refill it. if its coming out of the end of the axle then its more complicated... you have to remove the wheel, brake assembly, an then pull the axle out to replace the seal. then put it back together. either way the most expensive part is gonna be the labor. an that depends on the shop. if its leaking from the middle it should take 2 hours for a rookie mechanic. TOPS! if its out of the end... hard saying...
