Procedure

1. 1

   Remove skid plate and access components
   Remove front skid plate if equipped by removing mounting bolts. This provides access to the steering gear and power steering components. Clean area around steering components with brake cleaner to prevent contamination.

   Mounting Bolts37 Nm (27 lb-ft)
2. 2

   Disconnect power steering lines
   Using a flare nut wrench, carefully loosen the power steering line fittings at the steering gear. Have drain pan ready as fluid will drain. Cap or plug open lines immediately to prevent contamination. Note the orientation and routing of lines for reinstallation. Remove and discard old O-rings from fittings.
   ⚠Power steering fluid may drain rapidly once fittings are loosened. Keep drain pan positioned properly.

3. 3

   Disconnect tie rod ends
   Remove cotter pins from tie rod end castle nuts and discard. Loosen but do not fully remove the tie rod end castle nuts. Use pickle fork or tie rod separator to separate tie rod ends from steering knuckles. Remove castle nuts completely. Mark the position of tie rod adjustment sleeves with paint or marker to maintain alignment settings.
   ℹ️Marking tie rod positions helps maintain front end alignment during reassembly.

4. 4

   Disconnect intermediate steering shaft
   Locate the intermediate steering shaft coupling at the steering gear input shaft. Mark the alignment between the shaft and gear for proper reassembly. Remove the pinch bolt securing the intermediate shaft to the steering gear. Separate the intermediate shaft from the gear input shaft using light prying if necessary.
   ⚠️Do not rotate steering wheel or intermediate shaft once disconnected or clockspring damage may occur.
5. 5

   Disconnect electrical connector
   Locate the electrical connector on the Electric Power Steering module. Press the release tab and carefully disconnect the connector. Inspect connector terminals for corrosion or damage. Clean with electrical contact cleaner if needed.
   ℹ️Do not pull on wiring harness; press release tab fully before removing connector.
6. 6

   Remove steering gear mounting bolts
   Locate the steering gear mounting bolts that secure the rack assembly to the frame. Support the steering gear with one hand or have an assistant support it. Remove all steering rack mounting bolts. Note any spacers or shims for reinstallation in the same positions.
   ⚠Steering gear assembly is heavy. Ensure proper support before removing final mounting bolt.

7. 7

   Remove steering gear assembly
   Carefully lower and maneuver the steering gear assembly out from under the vehicle. May need to rotate or angle the assembly to clear frame and suspension components. Work slowly to avoid damaging brake lines or other nearby components.
   ⚠Assembly is bulky and heavy. Use proper lifting techniques and have assistance available.
8. 8

   Remove EPS module from steering gear
   With steering gear on workbench, locate the EPS module mounting hardware. Remove cover screws if applicable to access module mounting bolts. Remove the rack bolts or module mounting bolts securing the EPS module to the steering gear housing. Carefully separate the module from the gear assembly. Inspect gear housing mounting surface for damage or debris.

9. 9

   Install new EPS module
   Clean mounting surfaces on steering gear housing with brake cleaner and wire brush. Position new EPS module onto steering gear housing, ensuring proper alignment of mounting holes and drive mechanism engagement. Install rack bolts and tighten to specification. Install cover screws if applicable and torque to specification.

10. 10

    Reinstall steering gear assembly
    Carefully maneuver the steering gear assembly back into position under the vehicle. Align mounting holes with frame brackets. Install all steering rack bolts with any original spacers or shims in their original positions. Torque mounting bolts to specification in a cross pattern.

11. 11

    Reconnect intermediate steering shaft
    Align the intermediate steering shaft with the steering gear input shaft using the alignment marks made during disassembly. Slide shaft onto input shaft splines ensuring proper engagement. Install pinch bolt and torque to specification. Verify steering wheel is still centered and locked.
    ⚠️Ensure alignment marks match exactly to prevent steering wheel being off-center.
12. 12

    Reconnect tie rod ends
    Insert tie rod ends into steering knuckles. Install new castle nuts and tighten to specification. Ensure cotter pin holes align; tighten slightly more if needed but do not back off to align. Install new cotter pins and bend ends to secure. Verify tie rod adjustment sleeves are at the marked positions.

    Reconnect power steering lines
    Install new O-rings onto power steering line fittings. Lubricate O-rings lightly with ATF+4 fluid. Thread fittings into steering gear ports by hand first to prevent cross-threading. Use flare nut wrench to tighten power steering line fittings to specification.
    ⚠Start fittings by hand to ensure proper threading before using wrench.

    Fill and bleed power steering system
    Lower vehicle to ground. Fill power steering reservoir with Mopar ATF+4 to proper level. Remove steering wheel holding tool. Start engine and turn steering wheel slowly from lock to lock several times while checking fluid level. Add fluid as needed. Check for leaks at all fittings. Reconnect negative battery cable.
    ℹ️Expect some air bubbles initially. Continue cycling steering until fluid runs clear without bubbles.

Reassembly

1. Torque all fasteners to specifications in the order listed in the procedure.
2. Use new O-rings on all power steering line fittings.
3. Use new cotter pins on tie rod end castle nuts.
4. Ensure all electrical connections are fully seated and locked.

Verification

• Start engine and verify no warning lights related to power steering system.
• Turn steering wheel slowly from lock to lock and verify smooth operation with no unusual noises.
• Check all power steering line fittings for leaks with engine running.
• Verify power steering fluid level is correct and fluid is not foaming.
• Test drive vehicle at low speed and verify normal steering assist function.
• Recheck all mounting bolts and fittings for proper torque.
• Schedule front end alignment check to verify tie rod positioning.
