The hub bearing is replaced when there is play. Bearing wear can be determined by increased noise when driving.

Operations for replacing a hub bearing with and without ABS are similar. The only difference is the installed speed sensor in the steering knuckle.

Preparing the car for work. We install the car on a viewing hole or a lift.

In order to unscrew the hub nut, place stops under the wheels.

Usually, the hub nut is tightened with great force, so you need an assistant to apply the brake while unscrewing the nut.

Further assembly and installation of the hub assembly is carried out in the reverse order.

The fasteners listed below must be replaced:

- front wheel hub nut;

- nut of the bolt of fastening of the ball joint of the front suspension arm;

- nuts of the bolts of the steering knuckle to the front suspension strut.

Install the ball joint bolt of the lower arm of the front suspension to the steering knuckle with the head towards the front of the vehicle.

Install the spline shank of the front wheel drive shaft into the front wheel hub.

Install the steering knuckle on the front suspension strut, insert the mounting bolts and tighten, without tightening, new nuts (wrench 18, interchangeable head 18, ratchet wrench).

Install the ball joint pin of the front suspension arm into the steering knuckle, install the mounting bolt and tighten the new nut. Nut tightening torque 62 Nm (6.2 kgf.m) (wrench 16, interchangeable head 16, ratchet wrench, torque wrench).

Tighten the nuts of the bolts securing the steering knuckle to the front suspension strut. Nut tightening torque 105 Nm (10.5 kgf.m) (wrench 18, interchangeable head 18, torque wrench)

Connect the tie rod end to the knuckle arm.

- install the front brake disc cover;

- install front brake disc.

Install a stop on the front wheel hub and secure it with two wheel bolts.

Tighten the new front wheel hub nut and remove the stop. Nut tightening torque 280 Nm (28.0 kgf.m) (replaceable head 17, interchangeable head 32, knob, torque wrench).

- install the front wheel speed sensor;

- install the front brake assembly.

Install the front wheel. Press the brake pedal 2 - 3 times to set the pistons of the wheel brake cylinders to the working position.

Check and, if necessary, adjust the alignment of the front wheels.
