I have done both seals on my TR2, and I wasted hours attempting to
remove the outer hub with a screw-type extractor. 

To remove the outer hub from the axle shaft (to access the outer
seals), you will require the services of a hydraulic press. I suggest
the following procedure: 

1. Loosen the large axle nut. This is best accomplished with the road
wheel still in place, to help prevent the axle from rotating. This nut
is tightened to 120 lb-ft as I recall, so it is often tough to remove. 

2. Remove the complete hub/axle assembly by removing the six bolts
from the brake backing plate. 

3. Take the hub/axle assembly to your friendly machine shop, and ask
the proprietor to put it on his biggest, baddest hydraulic press.
Separating these components usually takes several tons of pressure,
and is announced by a very loud noise. 

Have fun!

        If you look down the bore of the axle you will see the inner axle
        seals about 6" in. These are not easy to get out, ahving changed 
        mine once. I finally settled on a slide hammer with a hook on it
        to pull the boogers out. I'm sure there are those who have hit on
        an easier way, but I don't know it. The outer seals are just plain
        nasty to get out. It usually require a mohunkas, great press to
        get the halves apart (there was a rather lengthy string about this
        process on the list just a couple weeks ago).
        I wouldn't worry about diff oil on the axle halves up to the inner
        seal. Anything beyond that would indicate a bad inner seal (another
        symptom would be oil leaking out of the shaft end behind the brake
        drum).Of the two jobs getting the inner seals out is definitely
        the easier.

        Good luck,

        Greg
