Thanks, i was also told to check the green,black wire running from ASD relay to ECM so I guess I have to take out the PDC out of the way along with coolant reservoir to get at it, motor mounts seem fine.
Noise under dash may be blend door,rear brake problem perhaps warped rotor also check rear balljoint,never knew they had one I know I just replaced one I have the same Jeep as yours, just a year newer
