How do you know if your 4WD is engaging? Recently acquired 92 XJ Laredo 4.0L
automatic with CommandTrac (166000mi). Partime light on dash comes on, but I
don't feel or hear any gears or linkage moving when I move the lever from
2WD to 4 HI. It hasn't snowed or gotten icy yet, so I don't want to drive it
in 4WD on dry pavement.

 

It's quiet. Jack up one side of the car and check if you can rotate the
front wheel.

Find some real loose gravel ... stop ... floor it for a second ... and
you'll know. A front wheel and a back wheel will have thrown gravel.

Make a sharp turn going real slow, you will hear wheel hop.
