Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks behind rear wheels
3. Loosen front wheel lug nuts while vehicle is on ground (do not remove)
4. With vehicle on ground and brakes applied, loosen but do not remove the 32mm axle nut using breaker bar
5. Raise front of vehicle and support securely on jack stands at manufacturer lift points
6. Remove wheel and tire assembly
7. Clean hub and suspension components with wire brush to facilitate disassembly

Procedure

1. 1

   Remove brake caliper and rotor
   Remove the two brake caliper mounting bolts and slide caliper off rotor. Support caliper with wire or bungee cord - do not let it hang by the brake hose. Remove brake rotor by pulling straight off hub. If rotor is stuck, use two M8 bolts in the threaded holes to press it off.
2. 2

   Disconnect ABS wheel speed sensor
   Locate the ABS wheel speed sensor on the back of the steering knuckle. Disconnect the electrical connector. Remove the sensor mounting bolt and carefully extract the sensor from the knuckle bore. Inspect O-ring and replace if damaged.
   Torque spec

   ABS Sensor Bolt11 Nm (8 lb-ft)
3. 3

   Remove axle nut and separate outer CV joint
   Fully remove the 32mm axle nut that was loosened during preparation. Remove and discard the cotter pin or staked collar. Push the axle shaft inward slightly to break it free from the hub splines. If stuck, use a brass drift to tap the end of the axle while supporting the hub.
   ⚠Do not strike the axle threads with a steel hammer - this will damage the threads and prevent proper nut installation.
   Torque spec

   Axle Nut250 Nm (184 lb-ft)
4. 4

   Separate lower ball joint and tie rod end
   Remove the lower ball joint castle nut and separate the ball joint from the steering knuckle using a ball joint separator tool. Remove the outer tie rod end castle nut and separate the tie rod from the knuckle. Support the knuckle assembly as fasteners are removed.
5. 5

   Disconnect strut-to-knuckle bolts
   Remove the two bolts connecting the steering knuckle to the strut assembly. These are large bolts with nuts on the backside. Note the alignment of any camber adjustment marks before removal. Carefully remove the knuckle assembly from the vehicle along with the hub.
   ℹ️Mark the strut-to-knuckle relationship with a scribe or paint pen if no factory alignment marks are visible. This helps maintain alignment during reassembly.
6. 6

   Remove hub from steering knuckle
   Secure the steering knuckle in a vise using soft jaws to protect the surfaces. Remove the four hub mounting bolts from the back of the knuckle. Use a hub puller tool to press the hub out of the bearing inner race. If resistance is high, carefully apply penetrating oil and allow to soak, then resume pressing.
   ⚠Do not use heat on the knuckle or bearing assembly as this can damage the bearing and alter the metallurgy of the knuckle.
   Torque spec

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

   Remove bearing inner race from hub
   After the hub is separated, the bearing inner race will likely remain pressed on the hub. Use a bearing race puller or press with appropriate adapters to remove the inner race from the hub shaft. Inspect the hub for any scoring, cracks, or damage. Replace hub if damaged.
8. 8

   Remove snap ring and press out old bearing
   With the knuckle still secured, use snap ring pliers to remove the bearing retaining snap ring from the knuckle bore. Position the knuckle on a hydraulic press with the bearing supported by a press plate or appropriate sleeve that contacts only the outer race. Press the bearing out of the knuckle, pressing from the back side toward the front.
   ⚠Support must contact the outer bearing race only. Pressing against the inner race or rollers will damage the bearing and potentially the knuckle.
9. 9

   Clean and inspect knuckle bore
   Thoroughly clean the bearing bore in the steering knuckle using a wire brush and clean shop towels. Remove all rust, debris, and old grease. Inspect the bore for any scoring, cracks, or damage. Check that the snap ring groove is clean and undamaged. The bore must be completely clean for proper bearing seating.
10. 10

    Press new bearing into knuckle
    Position the new bearing with the manufacturer markings facing outward (visible side). Place the knuckle on the press bed with proper support under the back side. Use a bearing installation sleeve that contacts only the outer race of the new bearing. Press the bearing squarely into the bore until it bottoms against the internal shoulder. Ensure the bearing is fully seated and sits flush.
    ⚠️Pressing on the inner race will destroy the bearing. Use only a driver sleeve that contacts the outer race around its full circumference.
    ⚠The bearing must be pressed in squarely. If it cocks at an angle, remove and restart the installation to avoid damaging the knuckle bore.
11. 11

    Install snap ring and verify bearing
    Install the bearing retaining snap ring into its groove in the knuckle bore, ensuring it is fully seated around the entire circumference. Verify the bearing is properly seated by checking that it does not move axially and that the snap ring is completely in its groove. If available, use a dial indicator to check bearing play - it should rotate smoothly with minimal endplay.
12. 12

    Press hub into new bearing
    Position the knuckle assembly with the bearing facing up. Align the hub with the bearing inner race bore. Use the hydraulic press with a hub installation sleeve that contacts the inner race of the bearing. Press the hub through the bearing until it is fully seated. The hub should press in smoothly with steady pressure. Verify the hub is fully seated and rotates smoothly.
    ⚠The press sleeve must contact the inner bearing race, not the hub flange or outer race. Pressing on the outer race will destroy the bearing.
13. 13

    Install hub bolts and check assembly
    Apply medium-strength threadlocker to the four hub mounting bolts if specified. Install the hub bolts from the back of the knuckle and torque in a crisscross pattern to specification. After torquing, verify the hub rotates smoothly without binding or excessive noise. Check that there is no axial play in the assembly.

    Hub Bolts102 Nm (75 lb-ft)
14. 14

    Reinstall knuckle assembly to vehicle
    Position the knuckle assembly back onto the strut and align with any reference marks made during disassembly. Install the strut-to-knuckle bolts and tighten securely but do not torque yet. Reconnect the lower ball joint and tie rod end, installing new castle nuts and cotter pins. Insert the axle shaft through the hub and thread on a new axle nut finger-tight.
15. 15

    Install ABS sensor and brake components
    Clean the ABS sensor bore and install a new O-ring if needed. Insert the wheel speed sensor and install the mounting bolt to specification. Reinstall the brake rotor, ensuring the hub face is clean. Mount the brake caliper and torque the mounting bolts to specification (refer to brake service procedure for torque values).

    ABS Sensor Bolt11 Nm (8 lb-ft)
16. 16

    Final torquing and wheel installation
    Torque the strut-to-knuckle bolts to specification (refer to suspension service procedure). Install the wheel and tire assembly. Lower the vehicle until the tire just contacts the ground. With the vehicle weight on the wheel and brakes applied, torque the axle nut to specification. Install a new cotter pin through the castle nut or properly stake the nut collar per manufacturer specification. Complete lowering of vehicle and torque wheel lug nuts in a star pattern.
    ⚠️The axle nut MUST be torqued with the vehicle weight on the wheel and brakes applied. Torquing while suspended can result in incorrect bearing preload.
    Torque spec

    Axle Nut250 Nm (184 lb-ft)

    Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

1. Ensure all fasteners are torqued to specification in the proper sequence
2. Verify the axle nut is properly secured with a new cotter pin or staked collar
3. Check that the wheel speed sensor connector is fully seated and secured
4. Verify no tools or parts were left in the wheel well area

Verification

• Test drive the vehicle at low speed and verify no abnormal noise, vibration, or pulling
• After initial test drive, re-verify axle nut torque and security
• Check for proper ABS operation - warning light should extinguish after startup
• Verify smooth steering operation with no binding or unusual feedback
• Schedule a professional wheel alignment as suspension components were disturbed
• After 50-100 miles, re-check wheel lug nut torque
