The carrier is the part inside the housing that holds the ring gear, spider gears, etc. It is made from nodular cast iron.
As for the rest, that's why they are called "stealerships". Those prices quoted for a carrier makes you realize just how overpriced many dealer items are. An E-locker from any aftermarket distributor is under $900. It is the exact, identical part to what the stealer sells, but the stealer wants to charge you $1000 more for it. $2400 for an open diff is just insane - it's a $200 part.
:agree:Dennis, I agreed that following the manufacturer's maintenance schedules is a good thing, and being more aggressive than that is even better. I disagree with following the dealer's maintenance schedules. They are often outdated and incorrect schedules, which is the point I've been trying to make here with David. An owner should start with what's in his owner's manual and not what is stated on the dealer's walls.
I also amend my schedules with gut instinct and common sense. Living here in the desert I know our fluids get taxed a bit more due to the heat. I realize that riding a lot of dusty trails can put more dirt (abrasives) into those fluids meaning I may check it more often. But again I start with a strong baseline which is what the manufacturer publishes for that vehicle.
