Rear locker won't engage

[fj40crusher]

My 97 with stock lockers. Put it in 4 low, turn diff switch and the lights blink. Front will engage but the rear just blinks. Tried backing up a little bit as well as going forward to see if it would catch but nothing.

I remember reading on here somewhere about a possible cause but can't find it now. Any ideas?

No noises, nothing odd just won't engage.

Turn sharply and drive in a circle. It will then lock. Or you can jack up one rear wheel and spin the wheel by hand. It will then lock.

If it doesn't then you need to diagnose wiring and diff lock motor.

Most likely, it's just a stuck actuator. Just needs to be worked every now and then.

 

[fj40crusher]

So how do you make it unstuck?

 

[Doc]

Mine was just a matter of hitting the lock/unlock switch a bunch of times and rocking the truck back and forth a bit.

the rear locker sometimes take quite a bit of driving to engage, it is coerse and the rear tires do not have as much diffrence in rotation in a turn as the fronts, find a large dirt/gravel area and engage the real locker, turn in a tight circle, it should engage, if not it may need excersice like doc said

Well, took off for some dirt. Took a few times but it finally engaged. Weird, it's never done that before. Guess I should get the wife out of my 80 so I can drive it more.

Now that I think about it, it's only been engaged in mud and snow in the past. I assume the rear wheels spinning engaged it easier.

Least it ain't broke

Yep, immediate

It's your 80's way of saying you dont wheel me enough

Yeah, it's just jealous that the 60 got some new parts.

Weird actually. Anytime I do something nice for one of my rigs one of the others will act out. It's like having 3 more children.

Is there a problem engagin them if one is spinning and the other is not?

My brain tells me that something could break doing that.

 

[Beowulf]

TF,
Your brain is right unless the "spinning" is a slowly turning wheel.

That's what I thunk so that's what I 've always done. Thanks Beo!
