    Do you mean the pinion on the rear diff?

    That would be the "pinion seal"!

    How easy is the pinion seal to replace? Mine is leaking too.

    My Chevy isn't broken, its just out of gas.

    yeah its the pinion seal and it pretty easy to do all you have to do is take the driveshaft off and the yoke on the diff its one nut its alot easyer if you do it on the ground just put the parking brake on

    You use a torque wrench to find out how tight it has to be when you put it back together. Very important. Remove yoke pop seal and instal is in reverse. Easy.
