Wheel Bearing Hub - Rear

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

Warnings

Tools required

Parts

• Rear wheel bearing hub assembly × 1 — Use OEM specification
• Axle nut × 1 — One-time use, replace
• Brake caliper bracket bolts (if corroded) × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Loosen rear wheel lug nuts while vehicle is on the ground (do not remove)
3. Loosen the rear axle nut while vehicle is on ground with parking brake applied and vehicle in park (breaker bar required)
4. Raise rear of vehicle and support securely on jack stands at manufacturer-specified jacking points
5. Remove rear wheel completely
6. Clean the work area around the hub assembly with wire brush to prevent contamination

Procedure

1. 1

   Remove ABS wheel speed sensor
   Locate the ABS wheel speed sensor on the back of the knuckle. Remove the 8mm bolt securing the sensor and carefully pull the sensor out of the hub assembly. Move the sensor and wiring harness out of the work area and secure it to prevent damage.
2. 2

   Remove brake caliper and bracket
   Remove the two caliper bracket bolts using a 17mm wrench or socket. Remove the caliper with bracket as an assembly. Support the caliper using wire or zip ties from the suspension spring to prevent strain on the brake hose. Do not disconnect the brake hose.
   ⚠Never let the caliper hang by the brake hose
3. 3

   Remove brake rotor
   Pull the brake rotor off the hub. If the rotor is stuck, use two M8 bolts threaded into the service holes on the rotor face to push it off. If rotor is severely rusted, light tapping with a rubber mallet on the hat section may help break it free.
4. 4

   Remove axle nut completely
   Remove the 30mm axle nut that was loosened during preparation. This nut is one-time use and should not be reused. Discard the old nut. If the nut was staked into the axle groove, use a punch to straighten the staked portion before removal.
   ⚠Axle nut must be replaced with new hardware, do not reuse

   Axle Nut200 Nm (148 lb-ft)
5. 5

   Remove hub assembly mounting bolts
   Access the four hub assembly mounting bolts from the rear side of the knuckle (behind the backing plate). These are 14mm bolts. Remove all four bolts completely and keep them organized as they will be reused.
   Torque spec

   Wheel Bearing Hub Bolts100 Nm (74 lb-ft)
6. 6

   Remove hub assembly from knuckle
   Pull the hub assembly straight off the knuckle. The axle shaft will slide out of the hub bearing. If the hub is stuck, carefully use a soft-faced mallet to tap around the perimeter of the hub to break it free. Do not pry against the ABS tone ring or backing plate.
   ⚠Do not damage the ABS tone ring on the hub assembly during removal
7. 7

   Clean mounting surfaces
   Thoroughly clean the hub mounting surface on the knuckle using a wire brush. Remove all rust, corrosion, and debris. Clean the backing plate area and inspect for damage. Clean the axle shaft splines and apply a light coat of anti-seize to prevent future binding.
8. 8

   Install new hub assembly
   Align the new hub assembly with the knuckle, ensuring the ABS sensor hole is properly positioned. Guide the axle shaft through the center of the new hub bearing. Push the hub assembly fully onto the knuckle until it seats completely against the mounting surface.
9. 9

   Install and torque hub mounting bolts
   Install all four hub mounting bolts from the rear of the knuckle. Start all bolts by hand to ensure proper thread engagement. Torque the bolts in a cross pattern to 97 Nm (71 lb-ft) to ensure even seating of the hub assembly.
   Torque spec

   Wheel Bearing Hub Bolts100 Nm (74 lb-ft)
10. 10

    Install new axle nut
    Install the new 30mm axle nut onto the axle shaft. Thread it on by hand as far as possible. Do not torque at this time - final torque will be applied with the vehicle on the ground. Tighten the nut snug to hold the hub in position.

    Axle Nut200 Nm (148 lb-ft)
11. 11

    Reinstall ABS wheel speed sensor
    Clean the ABS sensor tip and the sensor bore in the hub if necessary. Insert the ABS sensor into the hub assembly and install the mounting bolt. Torque the sensor bolt to 10 Nm (8 lb-ft). Ensure the wiring harness is properly routed and secured.
12. 12

    Reinstall brake rotor and caliper
    Slide the brake rotor onto the hub assembly. Apply medium-strength threadlocker to the caliper bracket bolt threads as recommended. Position the caliper and bracket assembly over the rotor and install the two bracket bolts. Torque the caliper bracket bolts to 100 Nm (74 lb-ft).
13. 13

    Install wheel and lower vehicle
    Install the wheel and thread all lug nuts by hand. Tighten the lug nuts in a star pattern until snug but do not torque yet. Lower the vehicle until the tire just contacts the ground but the suspension is not yet loaded.
14. 14

    Final torque all fasteners
    With the vehicle on the ground and parking brake applied, torque the axle nut to 200 Nm (148 lb-ft) using a torque wrench and 30mm socket. Stake the axle nut collar into the axle shaft groove using a punch and hammer. Torque the wheel lug nuts in a star pattern to 129 Nm (95 lb-ft). Fully lower the vehicle and remove jack stands.
    ⚠Axle nut must be staked after torquing to prevent loosening

Reassembly

1. Ensure all fasteners are torqued to specification in the correct sequence
2. Verify the axle nut is properly staked into the groove on the axle shaft
3. Check that the ABS sensor wiring is properly routed and not pinched or damaged
4. Confirm brake caliper bracket bolts have threadlocker applied

Verification

• Test drive the vehicle at low speed and verify no abnormal noise from the rear hub area
• Apply brakes and ensure normal brake function with no pulsation
• Verify no ABS warning light is illuminated on the instrument cluster
• After 50-100 miles, re-check the wheel lug nut torque
• Verify no excessive play in the hub by attempting to rock the wheel with vehicle raised
