grand cherokee what to look out for??...
 

My buddy is loooking at 01-04 grands and he wants to know what are common problems people may come across with these jeeps...
And I was wondering did they make the jeep with the 4.0 L I.6? I've seen a couple with them and was wondering if they just did a swap
Thanks shoot me any advice you may have its highly appreciated
Thank you!
