What makes a jeep grand Cherokee make a cracking noise when you cut the wheels all the way and drive?

Answer 1

You are probably in Part Time (4 wheel drive). Mine does make noise (tires cupping and tugging on steering wheel) when it is in PT. I have a 95 with Select Trac and the

vehicle info center tells me that it is in Part Time even when I have shifted it back to 2 WD. It shows all 4 tires engaged also and flashes "service four wheel drive switch".

Sometimes it gets back to normal on it's own. I adjusted transfer case shift linkage but still get errant message. Good luck
