Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
If you use the part time 4x4 on anything except dirt or snow, the
drivetrain will bind up. This will hold it in 4x4 until you reverse or
spin the tires or until it explodes something. I got stuck in 4x4
recently with no way to get off the highway for a few miles and was
lucky, I only exploded a front driveshaft u-joint. My old tenant did
the same and exploded his transfer case into little pieces.
I find with my high traction tires, I can even get bound up on dirt and
need to spin my tires in reverse to let it loose.
What happens is the front wheels take longer to go around a corner that
the rear wheels so a tire 'must' scuff the ground because the front and
rear driveshafts are locked together. If the tire can't scuff,
something breaks.
