I have been having problems with my 4WD. I have the newer motorized front axle engaging unit. I also have the floor lever style 4WD (no pushbuttons)

I took a look at the schematics, and there is a switch in the transfer case that provides electrical power to the front axle once the 4WD is engaged in the transfer case.

I checked power at the front axle with the transfer case in 4WD high. There was power available, and the engage signal was present.

My question to you is:

When the lever is in 4WD high or low, does that mean that the gears are engaged in the transfer case?

If so, that should mean that the transfer case switch should be engaged?

Has anyone had any problems with the replacement motor style front axle engaging units being intermittent or going out?

When the lever is in 4WD high or low, that means the front driveshaft should spin, correct?

Anything i am missing??
