I know I don't really use the center or front and rear dif locks, but have attempted to at least 'excercise' them after what I've learned here to keep them in good working order.
Campground this weekend had nothing but dirt/gravel roads so spent some time before leaving Sunday morning to 'excercise' them. Shifted into Low (in both park and neutral)and Center Dif lock would not engage. Tried driving forward and backward a little to see if it would, but after a half dozen attempts, gave up. It would Not engage.
Drove home and for yucks I tried one more time in the driveway before resigning myself to posting problem here first and then giving my friendly Yota dealer a call. Center dif locked up on first try!
Proceeded to then try to lock up rears and fronts, and both locked up immediately. Whew!
What could have been going on? Cold engine/tranny first thing, or just lack of use initially? Don't know why they would not lock first thing and then after a 270 mile trip lock right up. Wondered all the way home if something had been fawked up when the pinion seal and bolt had been replaced a couple of months ago? Apparently not at this point. Opinions?
