I have a leak coming from my rear differential. I looked underneath the truck and there is oil splattered underneath the truck like it has been slinging oil. There is also the same oil coming from the pan where the drive shaft connects underneath the engine(both ends where the drive shaft connect are leaking) What could be my problem and how expensive is it to fix. The truck has a bunch of miles on it and i'm wondering if I should just scrap this truck. I bought it for hunting purposes but this seems to be a big problem. Any advice would be appreciated.

Sounds like you've got leaking pinion seals and a leaking front output on your transfer case. Changing the pinion seals will require new crushsleeves as well. Leaking as badly as it sounds its possible the diffs have been run dry and may be damaged. Have it looked at by a reputable shop.
