When diagnosing a power steering rack leakage, be sure to identify the
location of the leak first before replacing the P/S rack. Some P/S rack
assemblies have been unnecessarily replaced.
To locate leakage, inspect the P/S system as follows:
- If the reservoir is at the specified level, the system is normal.
- If the reservoir is lower than the specified level perform the following
PRESSURIZING THE P/S SYSTEM
- Start the engine and let it idle.
- Turn and briefly hold the steering wheel fully to the right and left.
Repeat this step several times.
CAUTION: TO PREVENT DAMAGE TO THE STEERING SYSTEM, DO NOT KEEP THE
STEERING WHEEL IN THE FULLY TURNED POSITION FOR MORE THAN 15 SECONDS.
- Inspect the system paying close attention to the various fittings and
connections. If no leaks are found at these locations, remove the inner boot
clamp and pull the boot forward for inspection. Repeat this procedure for
the other side.
NOTE: The steering shaft is normally coated with heavy grease. Do not
confuse this with P/S fluid leakage.
