Hi,
Yesterday I tried to post an extensive post on my diff lock and high-low repair adventure, but I think it was too big and did not seem to go through. I read most posts and articles on fixing this, but could not find certain key pics, so I am offering mine up for anyone who finds them useful.
I also had to do some rework, because after fixing my diff lock my high-low still wouldn't work. I removed the solenoid as most people find it is the problem. Long story but it wasn't the solenoid but the actual linkage arm, so I followed Paul Grant's advice and removed the high-low cover as well, and cleaned and lubed everything. Now everything works perfect, it seems even better than when I got the Disco in 98. Please let me know of any questions. I have many details and tips but don't want to overwhelm one post.

Phase 1: Removed linkage and fixed shifter, cleaned and greased nicely; seemed to work well and re-assembled.

Phase 2: After fixing the diff lock the high-low still didn"t work so I tried the solenoid and eventually removed everything again and fixed the high-low arm that comes out of the cover. For phase 2 I had to dig deeper into the tunnel by removing the autoshifter and plate.
