Questions: Does the metal part or the rubber part go to the inside?

The metal part goes to the inside. This is the seal by your carrier bearings.

Questions: What is the best way to pull these. Do you have a special tool for pulling and then putting the new ones back in.
Question By: Anonymous on Sep 16 2012 12:00 AM
We usually just use a needle nose screw driver to get the old one out. You want to tap the new one in evenly and seat it.

Questions: I recently purchased 2 inner seals from you for my dana 44 on a 67 cj5. When I removed the differential there were no seals. Does this axle require inner seals inside the case? I didnt have issues with an oil leak. I was doing this as part of a restoration. I'm not sure why these seals are missing if they were required. I've had this jeep since the early 70s and dont recall work being done to the axle.
Question By: John on Feb 26 2012 12:00 AM
This is the inner seal that goes by the inner carrier bearings.
