I have the leak. Got the knuckle kit from JT Outfitters--now I think I need the install tool. would like to order one for my '77. Let me know ship to 33920(Alva, Fl.) and I'll send check(Garrett Esterer-correct?)Update!!!
I now offer two different seal installer tools. We just finished the first run for the 80-series axles. This tool also works for FF rear spindle seals!
These haven't been available in a couple if years but now they are. Specialty tool that makes installing the front inner axle seals much easier. Simply slip a seal ( stock or Marlin Crawler HD version ) onto the tool and then use a hammer to drive the seal in. The seal installer is designed specifically for the 40/45/55/60/62 and Minitruck inner axle seals. It also prevents the seal from being driven too far into the housing.
