4x4 won't always work!?

I authored one of the longer, more boring TOD meets PWM write-ups.

The biggest indicator of any type of TOD problem is the flashing red "TOD" indicator.
If it ain't working like it should, that light will tell you long before you sense something is amiss.

It's a pretty good system in that respect.

"Or, it may be working the way it is designed to work!"

True, I thought of that but forgot to put it in my response.

I had hub snap ring self-detached from the drive shaft, so sometimes 4x4 wont worked as expected. If it the case - check knuckle needle bearing, most likely it is dead as well.
