Thank You, I'm going to call it a WJ.

 

LOL a WJ is a whole different jeep. A jeep cherokee is an XJ as a grand cherokee is a ZJ and a new wrangler is a JK...

WJ - As the more bubble-shaped, aerodynamic replacement for the ZJ, it continues the Grand Cherokee name ('99-04).

OK, I got it now. It was my wife's daily driver, and it started acting up this year, so I'm going to turn it into a plow rig and needed to learn more about what makes it tick to make it dependable, thanks people.

 

Cool, good info, I wanted to know what the heck the difference was and was afraid to ask!
