    Heater core

    Looks like I need to replace my heater core on my 2000 Sport with the 4.0. Blows a little heat not much. This is an expensive fix. Has anyone done it in their cherokees? Looks like the whole dash has to come apart.

    Regear

    I just had my transmission rebuilt and the gentleman said I need to regear otherwise I’m going to burn the transmission out. It’s a 2000 Cherokee with the 4.0 and 3:55 gear ratio. Currently running 265/75/17 BFG Mud Terrains. Will I burn out my transmission?

    Losing coolant and temp gauge all over the place

    My 2000 Cherokee Sport is going thru coolant in the reservoir. It’s not leaking on the ground. My temperature gauge is reading 190-200. But it will go down to 100 and not register then go back up. Is the loss of fluid the head gasket or could it be something else?

    Low oil pressure

    My 4.0 in my 2000 Cherokee has low oil pressure. Mechanics say it’s due to oil leaks in the valve cover gasket and the oil pan gasket. Also where the oil filter goes is leaking. Could these issues really cause low oil pressure? Unfortunately due to a work related accident I can’t do this work...

    My 2000 with a Dana 35 in the rear started making a grinding noise. I pulled the cover and found shavings. I put a heavier weight oil in and the rear is making less noise.
