99 OEM Locker Fix

[Abe Nitro]

Hi,

The OEM locker in the 99 LC I just bought does not engage ( the dash indicator light keeps flashing when attempting to activate). I have tried the obvious rolling back ward and forward ect... Do any of you have ideas, or proven methods, on how to trouble shoot and repair this?

You tried engaging while driving with the wheels turned slightly too?

They usually are slightly frozen from their mall-cruising days.

 

[Abe Nitro]

Yep, but maybe I'll try again, thank you...

Reminds me of the words in the Owner's Manual:

"Difflocks should be engaged at least once per week"

I suppose it keeps them lubed.

I have a 99 LC with the optional rear diff lock. Is that what you are having trouble with? Or is it the center lock? Just curious if I should also be "excercising" mine. Sounds like I should be.

 

[Abe Nitro]

Yes, I am referring to the locking mechanism in the rear axle.

 

[tabraha]

You have the center diff locked when trying to engage the rear right?

edit: and you're in low range too?

 

[uHu]

Center diff locked is not a condition.
Low Range is. (and unless pin 7 mod is done, that means CDL is engaged)

There is of course a mod to enable RDL i Hi range as well, but that's another story.

One possibility is that the e-locker is mechanically stuck caused by disuse. (aka corroded)
I have never done it, but it should be possible to open the actuator to dislodge it if stuck.
Views, opinions, anybody?

Yes, I have attempted to lock it using the specified procedure, tcase in low, center locked. I have tried lots of gyrations. Starts stops turns reverse etc...
