How to Replace an ABS Wheel Sensor in a Chevy Corvette
- 1). Determine which ABS wheel sensor your Chevy Corvette will need. You'll want to be sure the new wheel sensor is compatible with your make and model of Corvette. The first Corvettes with ABS were introduced in 1983 and the wheel speed sensors are built into the wheel bearing/hub assembly. The entire assembly must therefore be replaced.
- 2). Disconnect the negative battery cable and remove the wheel with a socket wrench. Unplug the electrical connector for the wheel speed sensor. Remove the brake caliper and rotor with a socket wrench.
- 3). Support the lower control arm on the front wheels and disconnect it from the link for the stabilizer shaft. Separate the outer tie rod ball stud and lower ball joint stud from the steering knuckle using ball joint separator J-42188. Remove the wheel hub mounting bolts with a socket wrench and separate the wheel hub/bearing assembly from the knuckle.
- 4). Remove the connectors for the damping position sensor and shock absorber solenoid on the rear wheels if so equipped. Disconnect the axle nut with a socket wrench.
- 5). Detach the upper control arm and the lower control arm ball joint stud from their respective knuckles. Unfasten the wheel hub/bearing assembly bolts with a socket wrench and remove the wheel hub/bearing assembly.
- 6). Install the new wheel/bearing hub by reversing the removal steps and ensure the electrical connection for the wheel speed sensor faces rearward. Use a torque wrench to tighten the wheel bearing/hub assembly mounting bolts to 96 foot pounds.
- 7). Torque the nut for the lower control arm ball stud to 20 foot pounds plus a half turn and the nut for the outer tie rod to 33 foot pounds for the front wheels. Torque the bolts for the upper control arm to 22 foot pounds plus 195 degrees.
