Factory Locker Rebuild? (1 Viewer)

[jmvar]

Put the truck in low ratio or engage the cdl switch. Leave the trans in Neutral turn the Diff Lock switch to the rear position and then jack up one side of the rear axle and the front axle. Turn the rear wheel by hand. If the actuator is working it will engage and you will not be able to turn the wheel any more shoul not be able to turn it as it will be locked to the wheel sitting on the ground.

I have just spent the weekend wheeling in a river and the diff lock indicators flashed all the time even though the lockers were engaging as required. I need to get in and sort out the indicator switches.

Hey Sar, did you resolve your issue with the blinking diff light? I have the same problem, my rear locker engages, I can hear it and feel it, but the light is always blinking.

Any tips would be appreciated.

Thanks

in that case it is just the switch near the actuator, remove it clean it and actuate it by hand that usually fixes them.

I am talking about the set bolt that goes into the actuator arm.
The one you have to remove to pull the actuator out.
This is pics of the seal I asked about.

When I took my rear actuator off and used a 9V to move the arm out this little seal came out with it. I assume this is a seal that keeps gear oil from entering the actuator. Did you see anything like this when you took your rear apart or has anyone else noticed this seal?
