Steering Gear Replacement (Hydraulic Power Steering (HPS))
Tools Required
J 24319-B Universal Steering Linkage and Tie Rod Puller
Removal Procedure
Notice: Secure the steering wheel utilizing a strap to prevent rotation. Locking of the steering column will prevent damage and a possible malfunction of the SIR system. The steering wheel must be secured in position before disconnecting the following components:
* The steering column
* The intermediate shaft
* The steering gear
After disconnecting these components, do not move the front tires and wheels. Failure to follow these procedures may cause improper alignment of some components during installation and result in possible damage to the SIR coil.
1. Turn the steering wheel to the straight forward position, support it from movement.
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (Service Intervals) .
3. Remove the front tires and wheels. Refer to Tire and Wheel Removal and Installation (Service and Repair) .
4. Remove the tie rod end castle nuts.
Notice: Do not free the ball stud by using a pickle fork or a wedge-type tool. Damage to the seal or bushing may result.
5. Using the J 24319-B , separate the tie rod ends from the steering knuckles.
6. Remove the intermediate shaft to steering gear pinch bolt (1). Discard the bolt.
Important: Secure the steering wheel in the straight forward position before separating the intermediate shaft from the steering gear, or damage to the SIR coil will occur.
7. Separate the intermediate shaft (2) from the steering gear (3).
8. Loosen the transaxle mount through bolt.
9. Disconnect the heated oxygen sensor (HO2S) electrical connector.
10. Disconnect the HO2S sensor harness from the transmission mount bracket.
11. Remove the 3 transaxle mount to transaxle bolts.
12. Remove the 3 transaxle bracket to frame nuts.
13. Position the transaxle bracket and rear mount aside.
14. Remove the bolt (1) and disconnect the power steering gear inlet (2) and outlet (4) pipe/hoses from the power steering gear (3). Cap off the pipe/hoses and position aside.
15. Remove the power steering gear outlet pipe routing pin-style retainer from the right rear side of the frame.
16. Remove the power steering gear mounting bolts, nuts, and washers from the gear.
Important: The power steering gear will need to be rotated while it is removed through the left wheel opening.
17. Remove the power steering gear through the left wheel opening.
18. If the power steering gear is to be replaced, transfer the outer tie rod ends to the new steering gear.
Installation Procedure
Important: The power steering gear will need to be rotated while it is installed through the left wheel opening.
1. Position the power steering gear into the vehicle.
2. Connect the intermediate steering shaft to the steering gear.
Notice: Refer to Fastener Notice (Fastener Notice) .
3. Install the power steering gear mounting bolts, nuts and washers to the power steering gear.
Tighten the mounting bolts, nuts to 110 N.m (81 lb ft).
4. Install the power steering gear outlet pipe routing pin-style retainer to the right rear side of the frame.
5. Connect the power steering gear inlet (2) and outlet (4) pipe/hoses to the power steering gear (3) and install the bolt (1). Prior to tightening the retaining bolt (1), rotate the outlet pipe (4) clockwise/down so it touches the inlet pipe (2). Verify the hoses are still touching after the retaining bolt is tight.
Tighten the pipe/hose to power steering gear bolt to 27 N.m (20 lb ft).
6. Install the new intermediate steering shaft to steering gear pinch bolt (1).
Tighten the pinch bolt to 49 N.m (36 lb ft).
7. Position the transaxle bracket and rear mount back to their original position.
8. Install the 3 transaxle bracket to frame nuts.
Tighten the transaxle bracket to frame nuts to 50 N.m (37 lb ft).
9. Install the 3 transaxle mount to transaxle bolts.
* LZ4 Engines: Tighten the transaxle mount bolts to 90 N.m (66 lb ft).
* LZ9 Engines: Tighten the transaxle mount bolts to 50 N.m (37 lb ft).
10. Connect the HO2S sensor harness to the transmission mount bracket.
11. Connect the HO2S electrical connector.
12. Tighten the transaxle mount through bolt.
* LZ4 Engines: Tighten the transaxle mount bolts to 90 N.m (66 lb ft).
* LZ9 Engines: Tighten the transaxle mount bolts to 50 N.m (37 lb ft).
13. Position the outer tie rod ends into the steering knuckles.
Important: Hold the ball stud from turning during installation of the castle nut.
14. Install new torque castle nuts to the tie rod end ball studs.
Tighten the castle nuts to 25 N.m (18 lb ft) plus 90 degrees rotation.
15. Install the front tires and wheels. Refer to Tire and Wheel Removal and Installation (Service and Repair) .
16. Lower the vehicle.
17. Fill and bleed the power steering system. Refer to Power Steering System Bleeding (Service and Repair) .
