A friend of mine has a 99 GMC Yukon 1500 2WD with a 10 bolt rear. My questions is why is the axle in his truck so much expensive than one K5 blazer? I can get a 10 bolt for my blazer for $200 but the cheapest I can find one for his truck is $900. What am I missing? We have decided to just rebuild the one he has, but someone please enlighten me! Thanks!
