This procedure covers removal and replacement of the front wheel bearing hub assembly on a 2014-2019 Toyota Corolla with 1.8L I4 engine.

Warnings

Tools required

Parts

• Front wheel bearing hub assembly × 1 — Use OEM specification
• Axle nut (new) × 1 — 90179-36018 or equivalent
• New cotter pin for axle nut × 1 — Use OEM specification
• ABS sensor O-ring (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Loosen wheel lug nuts while vehicle is on the ground
3. With vehicle on ground and helper applying brakes, loosen (but do not remove) the 30mm axle nut using breaker bar
4. Raise front of vehicle and support securely on jack stands at manufacturer specified lift points
5. Remove wheel and tire assembly completely

Procedure

1. 1

   Remove axle nut
   Remove the previously loosened 30mm front axle nut completely and discard it. A new nut must be used during reassembly. Remove the old cotter pin if present.
2. 2

   Remove ABS wheel speed sensor
   Disconnect the ABS wheel speed sensor electrical connector. Remove the single 10mm bolt securing the ABS sensor to the steering knuckle. Carefully extract the sensor from the knuckle, noting the position and condition of the O-ring seal.
   ⚠ABS sensor is fragile. Do not bend or twist the sensor during removal.
   Torque spec

   ABS Sensor Bolt10 Nm (7 lb-ft)
3. 3

   Remove brake caliper and bracket
   Remove the two 17mm caliper bracket bolts securing the brake caliper and bracket assembly to the steering knuckle. Support the caliper assembly using wire or a bungee cord to prevent stress on the brake hose. Do not disconnect the brake hose.
4. 4

   Remove brake rotor
   Remove the brake rotor from the hub. If stuck, use two M8 bolts in the threaded holes on the rotor face to push it off, or tap gently with a mallet from behind.
5. 5

   Separate tie rod end
   Remove the cotter pin and castle nut from the outer tie rod end ball joint. Use a ball joint separator or pickle fork to separate the tie rod end from the steering knuckle. Count and record the number of threads visible on the tie rod for reassembly reference.
6. 6

   Separate lower ball joint
   Remove the bolt and nut securing the lower ball joint to the lower control arm. Use a pry bar or ball joint separator to separate the ball joint from the control arm, releasing the steering knuckle.
7. 7

   Remove hub assembly from knuckle
   Support the steering knuckle and CV axle. Remove the four bolts on the back side of the steering knuckle that secure the wheel bearing hub assembly (typically 17mm). The hub assembly will separate from the knuckle. Carefully slide the CV axle shaft out of the old hub assembly.
   ⚠Support the CV axle to prevent damage to the inner CV joint and differential seal.

8. 8

   Clean mounting surfaces
   Thoroughly clean the hub mounting surface on the steering knuckle using a wire brush. Remove all rust, debris, and old thread locker from bolt holes. Inspect the knuckle for cracks or damage.
9. 9

   Install new hub assembly
   Apply medium-strength thread locker to the four hub mounting bolts if specified by the hub manufacturer. Guide the CV axle through the new hub assembly and align the hub with the mounting holes on the knuckle. Install and hand-tighten all four mounting bolts before final torquing.

10. 10

    Reconnect steering and suspension
    Reconnect the lower ball joint to the control arm and install the bolt and nut. Reconnect the tie rod end to the steering knuckle, ensuring the same thread exposure as recorded during removal. Install the castle nut and new cotter pin.
11. 11

    Install brake components
    Install the brake rotor onto the hub. Clean the caliper bracket bolt threads and apply fresh medium-strength thread locker. Mount the caliper bracket and caliper assembly to the knuckle and torque the bracket bolts to specification.
    ℹ️Threadlocker is critical for caliper bracket bolts to prevent loosening.
12. 12

    Install ABS sensor
    Install a new O-ring on the ABS sensor if the original is damaged. Insert the ABS sensor into the knuckle bore and secure with the mounting bolt. Reconnect the electrical connector.

13. 13

    Install and torque axle nut
    Install the new 30mm axle nut onto the CV axle shaft. With the wheel still off and helper applying the brake pedal, torque the axle nut to specification. Stake the nut using a punch and hammer, or install a new cotter pin per the specific model year design.
    ⚠️Always use a NEW axle nut. Never reuse the old nut as it is a critical safety component.

    Axle Nut250 Nm (184 lb-ft)
14. 14

    Reinstall wheel and lower vehicle
    Install the wheel and hand-tighten the lug nuts in a star pattern. Lower the vehicle until the tire just contacts the ground. Torque the lug nuts to specification in a star pattern. Fully lower the vehicle and remove jack stands.

Reassembly

1. Verify all fasteners are torqued to specification
2. Ensure the axle nut is properly staked or has a new cotter pin installed
3. Confirm the ABS sensor connector is fully seated and secure
4. Check that brake caliper is properly secured and brake hose is not twisted or strained

Verification

• Test drive vehicle at low speed in a safe area and verify no abnormal noises from the wheel bearing area
• Verify ABS warning light does not illuminate on the dashboard
• Check for proper brake operation with no vibration or pulsation
• Perform a steering check to ensure proper tie rod end installation and alignment
• Re-torque wheel lug nuts after 50-100 miles of driving
• Have wheel alignment checked as suspension components were disconnected
