There is no such thing as a 2002 Cherokee Laredo. The last year for the Cherokee was 2001, and the last year it came with the Laredo trim was 1992. I have a 2003 Cherokee Laredo so this awnser makes no sense at all. Do you have a GRAND Cherokee Laredo? Those are still being made. They are not the same as the Cherokee.
