Replacement of the front wheel bearing hub assembly on a 2023 Chevrolet Bolt EUV, including removal of brake caliper, rotor, and axle nut.

Warnings

⚠️Do not work under a vehicle supported only by a jack. Always use properly rated jack stands.

⚠The axle nut is torqued to 250 Nm and requires a breaker bar to loosen. Loosen before lifting vehicle.

⚠Never allow the brake caliper to hang by the brake hose. Support it with wire or bungee cord.

ℹ️This vehicle is front-wheel drive electric. Ensure the vehicle is in Park and 12V battery is disconnected before beginning work.

Preparation

Chock the rear wheels securely
With vehicle on the ground, loosen wheel lug nuts 1/4 turn
With vehicle on the ground, loosen the axle nut using a breaker bar and 30mm or 32mm socket (nut is torqued to 250 Nm)
Disconnect the 12V battery negative terminal and wait 2 minutes
Raise vehicle and support securely on jack stands at manufacturer specified lift points
Remove the wheel completely

Procedure

1
Remove brake caliper assembly
Remove the two brake caliper bracket bolts from the rear of the caliper bracket. Support the caliper and bracket assembly with wire or a bungee cord to prevent stress on the brake hose. Do not disconnect the brake hose.
2
Remove brake rotor
Remove the brake rotor from the hub. If the rotor is stuck, use a rubber mallet to tap it loose. If equipped with rotor retaining screws, remove them first.
3
Disconnect ABS wheel speed sensor
Locate the ABS wheel speed sensor connector near the strut assembly and disconnect it. Remove the ABS sensor bolt securing the sensor to the hub assembly and carefully extract the sensor. Inspect for damage.
Torque spec
ABS Sensor Bolt10 Nm (7 lb-ft)
4
Remove axle nut
Completely remove the axle nut that was previously loosened. Discard the old nut as it is a one-time use component. The axle shaft will remain in the hub until the hub is removed.
5
Remove hub bearing bolts
Access the hub bearing bolts from the rear of the steering knuckle. There are typically 3 or 4 bolts securing the hub assembly. Clean the bolt area if corroded and apply penetrating oil if necessary. Remove all hub bearing bolts completely.
6
Remove wheel bearing hub assembly
Carefully pull the hub assembly away from the knuckle. The axle shaft will come through the hub as you remove it. If the hub is stuck, use a soft mallet to tap it from behind. Do not damage the axle shaft threads or CV joint boot.
7
Clean mounting surfaces
Thoroughly clean the hub mounting surface on the steering knuckle using a wire brush. Remove any rust, debris, or old thread locker. Ensure the mating surface is clean and flat for proper hub seating.
8
Install new wheel bearing hub
Guide the axle shaft through the center of the new hub assembly. Align the hub with the steering knuckle and push it into place. Ensure proper seating before installing bolts. The ABS sensor ring should face outward.
9
Install and torque hub bearing bolts
Apply medium-strength thread locker to the hub bearing bolt threads. Install all hub bearing bolts finger-tight, then torque in a crisscross pattern to specification. Verify all bolts are fully seated.
10
Install new axle nut
Install the new axle nut onto the axle shaft threads. Torque the axle nut to specification. The nut must be staked or secured according to manufacturer specification after torquing.
Torque spec
Axle Nut250 Nm (184 lb-ft)
11
Reinstall ABS sensor
Clean the ABS sensor bore in the hub if necessary. Install the ABS wheel speed sensor into the hub and secure with the sensor bolt torqued to specification. Reconnect the electrical connector.
Torque spec
ABS Sensor Bolt10 Nm (7 lb-ft)
12
Reinstall brake rotor and caliper
Install the brake rotor onto the hub. Remove the caliper from its support and position the caliper bracket over the rotor. Clean the caliper bracket bolt threads and apply thread locker as recommended. Install and torque the caliper bracket bolts to specification.
13
Reinstall wheel
Install the wheel onto the hub and hand-tighten all lug nuts. Lower the vehicle until the tire just contacts the ground. Torque the lug nuts in a star pattern to specification. Fully lower the vehicle and remove jack stands.

Reassembly

Reconnect the 12V battery negative terminal
Pump the brake pedal several times to ensure proper brake feel before moving the vehicle
Verify proper ABS sensor connection by checking for warning lights on the instrument cluster

Verification

Start the vehicle and verify no ABS or traction control warning lights are illuminated
Test drive at low speed and verify no abnormal noises from the wheel bearing area
Perform a series of gentle stops to verify proper brake operation
After 50-100 miles, re-torque wheel lug nuts to specification
Listen for any humming or grinding noises that could indicate improper installation
