    The other day my rear diff lock would not disengage. After a little messing with it and turning the steering wheel it finally did disengage. This brought a thought to mind; if I was in the middle of nowhere and it failed in the locked in position how could I disable it? If I remove the power (if it isn't a mechanical problem) would it disengage? Is there a fuse or can I unplug it? Does it need power to ENgage? Also what would happen if I accidently pushed the engage button when I was going down the highway? Is there an interlock to prevent that from happening?

    well it wont lock up if you have a 4wd and ur goin down the road til you throw it in 4 low from what ive heard. i have an 07 tacoma and mines hung up engaged b4 while i was workin on the electrical side of it in the cab. the only way i got it to disengage was to get under the truck and unplug it. i fiddled with it for several minutes b4 i finally just unplugged the electrical connection on top of the locker. that did it for me....... i dunno if it would work again tho.............

    I don't have a 4WD. The light switch is located right next to the rear diff lock switch. I just I hope I don't accidently hit the wrong one. It would be nice to have a cover that you have to flip up to have access to it.

    There shouldn't be any ill affects from driving with it engaged. Back in the day I drove my chevelle like that 24/7 They put those stupid speed limits on there to cover there asses. The only time having your rear locked is a problem is on a hard turn. The inside tire wants to rotate faster that the outer, rough on your tires if you don't take it easy.
    don't turn and let the hammer down or shit will break.

    My truck is a 2wd Prerunner. I read in the book that you should not go over 5 mph with it engaged. What if I was going down the road at 60 mph and I decided to turn on my lights that are operated by the switch next to the rear diff lock and accidently pushed it instead of the light switch?
