    I have a leak from the passanger rear differential axle seal. The Haynes manual actually uses the word "Easy" to describe this repair. One part I'm not sure about is how easy it is to take the axle out after you drop the differential. Also, other than the seal itself and the nut that holds the axle to the hub assembly, what other parts need replaced? Any info would be helpful!

    My differential went out so I'm planning on taking it out and getting it fixed. Is the reinstall the same and taking it out or do I need to take the calipers off and take the axle nuts off the hit them with a rubber mallet to seat them
