Power Steering Gear Replacement (Hydraulic)
Steering Gear Replacement (Hydraulic Power Steering)
Tools Required
J 24319-B Universal Steering Linkage and Tie Rod Puller
Removal Procedure
1. Turn the steering wheel to the straight forward position, support it from movement, and remove the key from the ignition.
2. Raise and support the vehicle.
3. Remove the front tires and wheels.
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 cradle/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 RH rear side of the cradle/frame.
Important: Convertible vehicles utilize a cross brace that is installed by sharing the cradle/frame mounting bolts. With the rear cradle frame bolts removed, it allows the cross brace to have movement to gain access to the power steering gear mounting bolts.
16. Convertible vehicles, support the rear of the cradle/frame with a suitable jack stand.
17. Convertible vehicles, remove the rear cradle/frame mount bolts.
18. 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 LH wheel opening.
19. Remove the power steering gear through the LH wheel opening.
20. 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 LH wheel opening.
1. Position the power steering gear into the vehicle.
2. Connect the intermediate steering shaft to the steering gear.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
3. Install the power steering gear mounting bolts, nuts and washers to the power steering gear.
Tighten
Tighten the mounting bolts, nuts to 110 Nm (81 lb ft).
4. Convertible vehicles, install the rear cradle/frame mounting bolts.
Tighten
Tighten the rear cradle/frame mounting bolts to 100 Nm (73 lb ft) plus 180 degree rotation.
5. Convertible vehicles, remove the jack stand.
6. Install the power steering gear outlet pipe routing pin-style retainer to the RH rear side of the cradle/frame.
7. Connect the power steering gear inlet (2) and outlet (4) pipe/hoses to the power steering gear (3) and install the bolt (1).
Tighten
Tighten the pipe/hose to power steering gear bolt to 27 Nm (20 lb ft).
8. Install the new intermediate steering shaft to steering gear pinch bolt (1).
Tighten

9. Position the transaxle bracket and rear mount back to their original position.
10. Install the 3 transaxle bracket to cradle/frame nuts.
Tighten
Tighten the transaxle bracket to cradle/frame nuts to 50 Nm (37 lb ft).
11. Install the 3 transaxle mount to transaxle bolts.
Tighten
- 3.5L Engines: Tighten the transaxle mount bolts to 90 Nm (66 lb ft).
