Remove 12 mm locking bolt from transmission (this one takes a couple of long
extensions to get to from above). It is hard to see. It is right next to the
diff lock sensor.
Disconnect two wiring harness connectors for diff lock motor (easiest to do
from the engine compartment but can be done from underneath).
Remove passenger side front tire. Remove the pasenger side splash shield.
Thse two steps might be skipped if you are using a hoist but you can see a
lot better if you do them.
Remove 17 mm bolt from end of diff lock motor.
Loosen three 12 mm bolts holding diff lock motor in place. Tap motor a
little to loosen it up and remove any preload from the shaft.
Insert flat blade screwdriver (you may have to grind down the sides to get
it to go in) into hole exposed by removal of 17 mm bolt. Turn diff lock
actuating rod 90 degrees clockwise (or, was that counter-clockwise? I can
never remember).
Remove three 12 mm bolts and remove diff lock motor.
You can bench test the diff lock by pulling out the rod and seeing if the
diff locks. If not, you have an internal transmission problem.
After cleaning and regreasing the diff lock motor (which solves 90% of diff
lock issues), be sure to put it in the unlocked position before reassmebly
and make sure the rod is pushed in.
Good luck,
Bob
