axle question

i have a 1972 mustang that i am replacing the axle seals on. i was inspecting under the car and i noticed streaks on my rear tire. i asuumed it was the brakes but after tearing it down i found it was the axle leaking. my question is what tool do i need to get the seal inside the axle tube out? do i need a slide hammer? also, how would i go about installing the new one?


one more quick question. i want to drain whatever oil is left in the axle housing, is there a drain plug i am missing or do i have to take the third member out to drain the oil?

There's rarely a drain plug for the axle. You need a seal puller to remove the seal, it's basically a hammer handle with a hook on the end to reach into the housing to hook the seal. New seal can be driven in with a broad flat punch, or any other similar shaped object. If there's no drain plug, the best way to completely drain the rear is pull the chunk. You'll need a new chunk gasket and copper crush washers for the studs. (if you go back without these, you could get seapage from around the studs.

so is the a fill plug? also, i would have to pull the other axle correct?
