Removal
PROCEDUREGround Cable Attachment At Strut Tower:
1. Remove the remote ground cable from the ground stud located on the left strut tower.
Correctly Isolated Remote Ground Cable:
2. Correctly isolate remote ground cable when servicing vehicle by installing the ground cable insulator on the strut tower ground stud as shown. This will prevent accidental grounding of the remote ground cable.
Brake Pedal Holding Tool Installed:
3. Using a brake pedal positioning tool such as shown depress brake pedal past its first 1 inch of travel and hold in this position. This will isolate the master cylinder reservoir from the brake hydraulic system, not allowing the brake fluid to drain out of the reservoir.
4. Raise vehicle on jackstands or center on a hoist.
5. Using Mopar, Brake Parts Cleaner or an equivalent, thoroughly clean all surfaces of the Hydraulic Control Unit (HCU). Also, thoroughly clean all brake line tube nut to HCU and proportioning valve connections.
Exhaust Pipe Mounting To Exhaust Manifold:
6. Remove the entire exhaust system from the vehicle as a complete assembly using following steps.
^ Remove attaching bolts from exhaust pipe at exhaust manifold on engine.
Exhaust System Support/Isolators Locations:
^ Remove all exhaust system support/isolators from the vehicle's exhaust system. Remove support/isolators from brackets on exhaust system components and leave attached to body of vehicle.
^ Lower exhaust system as a complete assembly away from the underbody of the vehicle.
Right Side Splash Shield:
7. Remove right side engine compartment splash shield from the vehicle.
HCU Heat Shield:
8. Remove the HCU heat shield from the HCU mounting bracket.
Electrical Connections At HCU And Relay Box:
9. Disconnect the 6 way connector from the HCU wiring harness and the 10 way connector from the relay box located on the HCU.
Brake Tubes At HCU:
10. Remove the brake tube routing clip from the HCU mounting bracket. Then remove the 2 brake tubes coming from master cylinder and the brake tube going to the left front wheel from the HCU ports.
Rear Brake Tubes And Right Front Brake Tube At HCU:
11. Remove the 2 rear brake tubes from the proportioning valves and the right front brake tube from the outlet port of the HCU.
Front Attachment Of HCU To Mounting Bracket:
12. Remove bolt attaching the front of the HCU to its mounting bracket.
Rear Attachment Of HCU To Mounting Bracket:
13. Remove the 2 bolts attaching the rear of the HCU to its mounting bracket. If vehicle being serviced is equipped with a 2.5L engine, remove the tube as indicated. Removing this tube will make it easier to remove the HCU assembly from the vehicle.
Removal Of HCU Assembly From Vehicle:
14. Remove HCU from its mounting bracket. Then remove HCU from vehicle out through the exhaust tunnel in the floor pan of the vehicle.
