Rear diff lock?

Has anyone else experienced this?

Hit the “lock rear diff” button and the rear did not lock. I rolled back and fourth before putting it under torque. I climbed up the little hill and let the tire spin slowly for a good 7seconds before I let off.

Is there a trick to this? Do I need to tap the breaks like military or something? Does the rear locker just not work?

Post is never fun without a picture so.. and had to put it in 4x4 to climb up the hill.

 

More than likely the motor is stuck or burnt up. I had one and the light on the dash would blink at me when I tried to engage it. Also you have to be in 4Lo for it to work.

 

Hitting the button, your light should flash on your dash.

It's only once the light stops blinking and remains solid, that you've engaged your locker; this is confirmed with an audible noise as well.

If you're having trouble making the locker engage, just drive forward or backward while turning. This causes one wheel to turn at a different speed than the other in the rear so that things "line up".

If your locker is still not working well, I'll leave the rest to help you with that one.

 

Yes, that would explain the blinking light on the dash. I’ll have to put it into four low tomorrow and see if that changes anything. With the scenario I put the rear end in today, it should have engaged. If it’s only 4low that engages it, would putting a limited slip diff in be worth it? Just seems silly for have a 4low only. Also explains why I can’t do a dang donut! haha

 

Assumed he knew to put it in 4lo, thanks!
