Wondering if anyone has experience with their rear diff locking by itself, =
with the switch turned off? Only happens when begin to go up a hill; ie: fr=
ont of car somewhat higher than the rear. Have checked the switch, mechanic=
ally nothing is loose. It will operate properly when switch is activated. A=
t this point I have the diff system disabled to protect it, but now is the =
season to have it operable. Any help, point me in right direction? thanks v=
ery much
