    <font color=red>I have a 10 bolt axle, and gear oil is leaking out of the passenger axle shaft.

    It's not too bad of a job. Most any repair manual will cover it. Basically, you put the rear on jack stands, take off tires, brake drums, and differential cover. There will be a small bolt or pin holding in a 'cross shaft' that the spider gears ride on in the diff. carrier. take that bolt/pin out, remove the cross shaft and push in slightly on the axles from the tire end of them. You can then pull out the 'c' clips from the axle ends in the diff. carrier, then pull out the axles. The seals and bearings are just inside of the tire side of the axle tube. Pry out the old seals and replace with new. Inspect axle where bearings run for worn or pitting. Either is bad. Might as well replace bearings while you're there. They can be tough to get out. Rent or borrow a bearing puller from the parts store. Install reverse of removal.

    Sorry forgot to say front axle
     
  4. Should be the same, but you take off the front rotor instead of the brake drum.

    The front end is a way bigger job. The axle seals are at the differential end of the axle. You have to pull the diff out of the housing to get to those seals. [​IMG] To get the diff out, you have to remove both axles. To remove the axles you have to pull the calipers, rotors and spindles. [​IMG]

    There's probably some dirt caked up inside the axle tube, that chewed up the seal. You should clean out the tubes extremely well before you reinstall the axles or you'll just push more dirt into the new seals.
