Bug - Replacing that pivot shaft seal is not difficult. But requires some extensive disassembly: The lower bolster must be removed, then the steering worm wheel pulled. Finally the pivot shaft must be dropped from the front end. And the seal itself can be tough to install due to it's position deep up in the "crotch" of the upper bolster casting.
Further my experience has been that even when a new seal is installed, depending on the condition of the pivot shaft seal surface the new seal may still leak too.
Now I simply pack the steering box full of good quality grease (corn head grease or similar). Even with old seal I've never had one leak a drop. And the grease lubes the worm and sector just fine - a couple of mine have been on grease for 10+ years now.
