    after some light wheelin this weekend i noticed fluid leaking from my rear differential wheere the drive shaft enters it. Anybody know what could be causeing this or have any tips on how to fix this? Im assuming there is some sort of seal inside here. I've never opened one up so i wouldnt know.

    Pinion seal.. You have to remove the pinion to replace it. It's a pain if not impossible if you don't have the right tools.

    it aint that bad.

    1. Put truck in air
    2. remove tires,brake drums
    3. pull cover, remove center pin/c-clips(if pin is broken go to step 12)
    4. pull axle shafts out.
    5. unbolt main caps. (REMEBER WHICH IS FOR WHICH SIDE and what is up and down)
    6. remove carrier
    7. remove d-shaft
    8. on the pinion yoke, not how many threads are exposed, then take a chisel or something of the like and score the nut, adn pinion so they can be lined up later.
    9. remove nut, pinion
    10. replace seal.
    11. repeat in reverse order. (be sure to NOT go past your scribed line on the pinion)

    12. walk away pitching afit. thencome bcak witha drill, screw outs and a beer. adn have "fun" lol

    assuming this is on a 10 bolt
    to do it the easy way (not the corect way but the i did it this way and havn't had any problems yet) you don't need to do the steps in red
    to do it the correct way you need to replace the pinion seal which is a pain
