Wheel Bearings
ADJUSTMENT
REMOVAL & INSTALLATION

The details are as follows :----

Adjustment

The wheel bearings are sealed units and are not adjustable.

Removal & Installation

Before servicing the vehicle, refer to the precautions section.

Remove or disconnect the following:

Rear wheel
Brake hose bracket mounting bolts from the trailing arm and the knuckle
Brake caliper
Wheel speed sensor
Spindle nut
Brake rotor
Upper ball joint
Lower arm (A)
Lower arm (B) from the trailing arm

Support the lower arm (B)

Steering knuckle

Press the hub out of the wheel bearing.

Splash guard
Snapring and press the wheel bearing out of the steering knuckle

If necessary, press the inner bearing race off of the hub.
Fig. Exploded view of the rear wheel bearing assembly

To install:

NOTE

Use a new ball joint nut, split pin, snapring and spindle nut for assembly.

Press the bearing into the steering knuckle and install the snapring.

Install the splash guard.

Press the hub into the bearing.

Install or connect the following:

Steering knuckle. Tighten the flange bolt to 54 ft. lbs. (74 Nm) and the lower shock nut to 47 ft. lbs. (64 Nm)
Lower arm (B) to the trailing arm and tighten the bolts to 47 ft. lbs. (64 Nm)
Lower arm (A)
Upper ball joint and tighten the nut to 40 ft. lbs. (54 Nm)
Brake rotor and tighten the screws to 7 ft. lbs. (9 Nm)
Spindle nut and tighten to 181 ft, lbs. (245 Nm)
Wheel speed sensor
Brake caliper and tighten the bolts to 41 ft. lbs. (55 Nm)
Brake hose bracket mounting bolts to the knuckle and trailing arm
Rear wheel

Check the wheel alignment and adjust as necessary.

This details will help.

Thanks.

The procedure to replace wheel speed sensor is as follows :---

Wheel Speed Sensor

Each wheel has its own wheel speed sensor which sends a small AC signal to the control module. Correct ABS operation depends on accurate wheel speed signals. The vehicle's wheels and tires must all be the same size and type in order to generate accurate signals. If there is a variation between wheel and tire sizes, inaccurate wheel speed signals will be produced.

WARNING

It is very critical that the wheel speed sensor(s) be installed correctly to ensure continued system operation. The sensor cables must be installed, routed and clipped properly. Failure to install the sensor(s) properly could result in contact with moving parts or over extension of sensor cables. This will cause ABS component failure and an open circuit.

Acura uses a contactless type of sensor that detects the rotating speed of the wheel. It is constructed of a permanent magnet and a coil. Attached to the rotating parts are gear pulsers (aka. Tone Rings). When these pulsers turn, the magnetic flux around the coil in the wheel sensor alternates its current. This generates voltages in a frequency or wave pattern. These wave pulses are sent to the ABS control unit which identifies the speed of each of the four wheels.

See Figure 1

REMOVAL & INSTALLATION

See Figure 2

Fig. Fig. 2: Typical front and rear wheel speed sensor mounting

CAUTION

Vehicles equipped with air bag systems (SRS) have components and wiring in the same area as the front speed sensor wiring harnesses. The air bag system connectors are yellow. Do not use electrical test equipment on these circuits. Do not damage the SRS wiring while working on other wiring or components. Failure to observe correct procedures may cause the air bag system to inflate unexpectedly or render the system totally inoperative.

Raise and safely support the vehicle as necessary for access.

Make certain the ignition switch is OFF .

Detach the sensor harness connector.

Beginning at the connector end, remove grommets, clips or retainers as necessary to free the harness. Take careful note of the placement and routing of the harness; it must be reinstalled in the exact original position.

Remove the bolt holding the speed sensor to its mounting; remove the sensor. If it is stuck in place, gently tap on the side of the mounting flange with a hammer and small punch; do not tap on the sensor.

To install:

Place the sensor in position; install the retaining bolts loosely. Route the harness correctly. Avoid twisting or crimping the harness; use the white line on the wires as a guide.

Once the harness and sensor are correctly but loosely placed, tighten the sensor mounting bolts. Tighten bolts to 16 ft. lbs. (22 Nm).

Working from the sensor end to the connector, install each clip, retainer, bracket or grommet holding the sensor harness. The harness must not be twisted. Tighten any bolt holding brackets to 7 ft. lbs. (10 Nm).

Attach the wiring connector.

Use the ABS checker to check for proper signal from the wheel speed sensor.

Carefully lower the vehicle to the ground.

INSPECTION

See Figure 3

Fig. Fig. 3: You must check the gap between the pulser and wheel speed sensor

Use a non-metallic feeler gauge to measure the gap between the sensor and the pulser.

Rotate the hub or axle slowly by hand, taking measurements at several locations.

Specifications are as follows:

Integra front and rear0.0160.039 inches (0.41.0mm)

Legend front0.0240.047 in. (0.61.2mm)

Legend rear0.0120.051 in. (0.31.3mm)

Vigor front0.0240.035 in. (0.60.9mm)

Vigor rear0.0200.035 in. (0.50.9mm)
