I have a 83 4x4 pickup, the pinion seal started leaking today and i need to take this on a 1k round trip next weekend, I was wondering what needs to be done to put the new seal in. Labor times are 2hrs, but i cant see why it takes that long, i called a shop they said itll be 115$ to do the seal so it cant be that in depth to do, i also bough the seal and by the looks of it you just pull the driveshaft then pull the seal out , WTF am i missing ? thanks guys!!!
