This procedure covers the removal and replacement of the power steering rack assembly on a 2012-2017 Toyota Camry with the 2.5L I4 engine, including disconnecting tie rods, steering column, hydraulic lines, and mounting hardware.

Warnings

Tools required

Parts

• Power steering rack assembly × 1 — Use OEM specification
• Power steering line O-rings × 4 — Included with rack or purchase separately
• Tie rod end cotter pins × 2 — Standard automotive cotter pins
• Steering intermediate shaft U-joint bolt × 1 — Replace if worn or damaged

Fluids

• Toyota ATF Dexron III — 1 qt

Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks behind rear wheels
3. Turn steering wheel to straight-ahead position and mark position relative to column
4. Disconnect negative battery terminal and wait 90 seconds for airbag system to discharge
5. Raise front of vehicle and secure on jack stands at proper lift points
6. Remove both front wheels
7. Place drain pan under power steering rack area
8. Remove engine under covers if equipped

Procedure

1. 1

   Remove power steering fluid from reservoir
   Use a turkey baster or fluid transfer pump to remove as much power steering fluid as possible from the reservoir. This minimizes spillage when disconnecting lines. Dispose of old fluid properly.
2. 2

   Disconnect tie rod ends from steering knuckles
   Remove the cotter pins from both tie rod end castle nuts and discard them. Loosen but do not fully remove the castle nuts. Use a tie rod end separator or pickle fork to break the taper connection between the tie rod end and steering knuckle. Once separated, remove the castle nuts completely and set tie rod ends aside.

3. 3

   Access and mark steering intermediate shaft
   From inside the vehicle, locate the steering intermediate shaft U-joint connection below the steering column. Mark the relationship between the shaft and the rack pinion shaft with paint or a scribe for reassembly reference. Remove the pinch bolt securing the U-joint to the rack pinion shaft. Separate the intermediate shaft from the rack by pulling upward.
   ⚠Do not allow the steering wheel to rotate after disconnecting the shaft to prevent clockspring damage.
4. 4

   Disconnect power steering pressure line
   Locate the high-pressure line connection at the rack. Use a line wrench to carefully loosen and remove the pressure line fitting. Be prepared for fluid spillage. Cap or plug the line and rack port to prevent contamination. Inspect the O-ring and discard it.
   ⚠Use a line wrench to prevent rounding off the fitting. Standard wrenches may strip the soft brass fittings.

   Pressure Line Fitting34 Nm (25 lb-ft)
5. 5

   Disconnect power steering return line
   Use a line wrench to loosen and remove the return line fitting from the rack. Allow fluid to drain into the pan. Cap or plug the line and rack port. Remove and discard the O-ring.
   Torque spec

   Power Steering Line Fittings30 Nm (22 lb-ft)
6. 6

   Remove rack mounting brackets
   Locate the two rack mounting brackets that secure the rack to the front subframe. Each bracket is held by two bolts. Remove all four mounting bolts while supporting the rack with one hand or having an assistant hold it. The rack is heavy and will drop when the last bolt is removed.
   ⚠The rack assembly weighs approximately 25-30 lbs. Support it properly to prevent dropping and causing injury or damage.
   Torque spec

   Rack Bolts102 Nm (75 lb-ft)
7. 7

   Remove rack assembly from vehicle
   Carefully maneuver the rack assembly out through the driver side wheel well opening. You may need to rotate and angle the assembly to clear the subframe and other components. Watch for sharp edges and avoid damaging brake lines or other nearby components. Lower the rack to the ground once clear.
   ℹ️This step may require patience and multiple angles. Do not force the rack as this can damage boots or other components.
8. 8

   Prepare new rack assembly
   Unbox the new rack assembly and verify it matches the old unit. Check that all mounting points and connections are identical. Install new O-rings on all hydraulic line connection points, lubricating them lightly with power steering fluid. Ensure the rack is in the center position by measuring equal boot extension on both sides.
9. 9

   Install new rack assembly
   Carefully guide the new rack into position through the driver side wheel well, reversing the removal process. Align the rack with the mounting bracket locations on the subframe. Ensure the rack pinion shaft is accessible from inside the vehicle cabin.
   ⚠Do not damage the new rack boots during installation. Torn boots will lead to premature rack failure.
10. 10

    Install rack mounting brackets and bolts
    Position both mounting brackets over the rack and align with the subframe bolt holes. Install all four mounting bolts hand-tight first to ensure proper alignment. Once all bolts are started, torque them to specification in a cross pattern to ensure even clamping force.

11. 11

    Reconnect steering intermediate shaft
    From inside the vehicle, align the intermediate shaft U-joint with the rack pinion shaft using the alignment marks made during disassembly. Ensure the shaft slides fully onto the splines. Install the pinch bolt and torque to specification per service manual. Verify the steering wheel is still in the straight-ahead position.
    ⚠Misalignment of the intermediate shaft can cause steering binding or poor centering. Verify marks are aligned before tightening.
12. 12

    Reconnect power steering lines
    Install the pressure line fitting to the rack with a new O-ring, tightening by hand first to ensure proper thread engagement. Use a line wrench to torque to specification. Repeat for the return line. Ensure fittings are not cross-threaded and O-rings remain properly seated.

13. 13

    Reconnect tie rod ends to steering knuckles
    Insert the tie rod end studs into the steering knuckle tapers. Install the castle nuts and torque to specification. Install new cotter pins through the castle nut slots and bend the ends to secure. If the cotter pin holes do not align, tighten the nut slightly more until they do—never loosen to align.
    ⚠Always use new cotter pins. Reused pins may fail and allow the tie rod to separate, causing loss of steering control.

    Reinstall wheels and lower vehicle
    Reinstall both front wheels and hand-tighten lug nuts in a star pattern. Lower the vehicle until the wheels just touch the ground but the suspension is not yet loaded. Torque the lug nuts to specification in a star pattern. Fully lower the vehicle and remove jack stands.
    Torque spec

    Wheel Lug Nuts136 Nm (100 lb-ft)

    Fill and bleed power steering system
    Fill the power steering reservoir with Toyota ATF Dexron III to the cold fill line. With the engine off, turn the steering wheel fully left and right several times to purge air from the system. Check fluid level and add as needed. Start the engine and let it idle. Turn the steering wheel left and right again, checking for leaks at all connections. Top off fluid to the hot fill line. Test drive and recheck fluid level when hot.

Reassembly

1. Reinstall engine under covers if removed
2. Reconnect negative battery terminal
3. Verify steering wheel is centered when wheels are straight ahead
4. Check all hydraulic connections for leaks after test drive
5. Monitor power steering fluid level for the first few days of operation

Verification

• Start engine and verify no power steering fluid leaks at rack or line connections
• Turn steering wheel fully left and right—should move smoothly without binding or noise
• Test drive vehicle at low speed in a safe area to verify proper steering operation
• Check that steering wheel returns to center after turning
• Verify steering wheel is centered when driving straight
• Schedule front-end alignment within 24 hours of completing this repair
• Recheck power steering fluid level after test drive and top off if necessary
