Well I finally got around to replacing this seal, It installs from the CAD opening. It was fairly simple. I pulled the right outer shaft, the posi lock and shift fork. Removed the slide collar. Then used a 24" screw driver to pop the old seal into the CAD housing by hitting the screwdriver through the axle tube. Then used a seal installer disc that fit the new seal to push start the seal into place thenused a bolt and nut to pull the seal into place. The axle shaft has a slight groove but was easily polished smooth. No more leaky axle seal.... <img src="/forums/images/graemlins/pfft.gif" alt="" />
