Rear Differential Lock Question

Is there a way to test the Rear Differential Lock to see if it is working with out taking the vehicle off road into the mud, my dash light come's on when I turn the switch on. thanks

 

get one wheel off.....then video tape

 

Chock the front wheels, jack up the rear of the truck. Put it in neutral.

Spin one wheel by hand. If the opposite wheel spins in the opposite direction, then the locker IS NOT engaged. They should both spin in the same direction.

Obviously, you've gotta be in 4lo - hopefully the system will allow the locker to stay engaged while you're in neutral.

however do the grey wire mod, then you can use the locker whenever you want

 

doesn't it only work in 4W LO?

 

Yup but if you do the grey wire mod you can use it whenever you want.

^^^ This is true, the grey wire mod does work. Also, if you have the ignition turned on, but the truck not running, you can put your transfer in 4low, then engage the locker button. Standing outside the vehicle you should be able to hear the locker engage.

 

This tip worked thanks a bunch, should I be engaging this periodically to keep it from seizeing up like my emergency brake cable did due to the previous owner not useing it?

 

i wouldnt think that would hurt. tho i do suggest u do the grey wire mod i did it a couple days ago and i love it.

 

x2. I run the locker through its paces occasionally now in dirt parking lots by doing a doughnut or two.
