I was playing in the snow and locked it in 4 lock. I was going slow and the light quit flashing, after another 15 feet a blasted through a snow drift and while entering the driveway, the front right wheel gained traction. I heard a pop like the diff didn't hold the wheels locked together and the steering slightly jerked left. It disengaged properly after I heard that, and continues to work properly. What noise did I hear, any damage? All works fine now, and yes, the light was not flashing. Thanks.
Heard something similar after getting stuck in the snow and locking the diff, several lock/unlock cycles later the diff still would not lock. I figured out that rolling forward or back slowly or getting in the gas very gently if you're stuck seems necessary to get the thing to lock properly. Mine's been fine since, you're probably good to go!

I have kind of a similar problem. I was stuck in snow and i engaged my Diff Lock. I was holding the override button and had the tries spinning fast. I heard a pop sound in the diff and after i got it out i realized my diff was not locking both front tires. i jacked both front and rear tires up and tried holding the front right tire with diff lock engaged and i can hold it back while giving it throttle. So the Diff is not working but it still engages normally and i heard it moving when i press the button but its not locking. There is no difference from normal 4x4 to diff lock but there is also no weird noises. Any ideas?
