I have replaced both seals on my TR2, and I wasted hours attempting to remove the outer hub with a screw-type extractor. My TR2 has a later Girling axle, rather than the original Lockheed axle fitted to the TR2.
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:
An additional trick, suggested by Steve Daniels ( firstname.lastname@example.org ), is to heat the hub and axle stub after they are set up in the press, and then apply a bar of paraffin wax. In a melted state, the paraffin is thinner than water, and will infiltrate the tapered fit through capillary action. After waiting about 10 or 20 seconds, apply the load on the press -- the hub should come loose much more easily than without using this technique. Since learning this from a friendly machinist, Steve hasn't bent anymore hubs!
