During the test drive check to ensure the 4x4 transfer case lever shifts smoothly into 4H and 4L and that the 4WD light illuminates when 4WD is engaged and does not blink or flash. I screwed myself by not questioning when one of the trucks I bought was very stiff when engaging into 4L when test driving it. Now I have to pull my transfer case and clean out the detent plunger.
