SUSPENSION AND STEERING SYSTEMS
WARNING 1: Refer to Section 2 and follow all safety precautions before working on this system.
WARNING 2: Wait until the vehicle is completely cool before beginning this procedure.
2001 THROUGH 2003 MODELS
- Refer to Chapter 6 and disconnect the cable from the negative terminal of the auxiliary 12-volt battery. Be sure to perform the initialization procedure when reconnecting it.
- Remove the high-voltage safety plug (see Section 2). Be sure to wait at least five minutes before proceeding. Drain the coolant from the inverter/converter/transaxle cooling system (see Chapter 1).
- Disconnect the battery cable from the inverter/converter. Cover it with vinyl electrical tape.
- Remove the four small Torx-head screws from the cover.
- Remove the two larger Torx-head screws from the circuit breaker sensor and connector cover.
- Use a voltmeter to test for voltage between each pair of the three terminals and also between each terminal and a good ground. The meter must read approximately zero volts everywhere. If not, wait for the system to discharge further. When all points read zero volts, proceed.
- Remove the six bolts and disconnect the three cables for motor/generator #2.
- Remove the three bolts and the cable from motor/generator #1. You will remove the cable along with the inverter/converter later.
- Remove the bolt and the ground cable.
- Place rags around the inverter/converter to catch coolant. Disconnect the three coolant hoses from the assembly.
STEERING SYSTEM | GENERAL INFORMATION
All models are equipped with rack-and-pinion steering. The steering gear operates the steering knuckles via tie-rods. The inner ends of the tie-rods are protected by rubber boots that should be inspected periodically for secure attachment, tears and leaking lubricant.
The power assist system is made up of an electric motor mounted to the steering gear on 2001 through 2003 models and higher on the steering shaft on later models.
The steering wheel operates the steering shaft, which actuates the steering gear through universal joints. Looseness in the steering can be caused by wear in the steering shaft universal joints, the steering gear, the tie-rod ends, or loose retaining bolts.
