## Power Steering

#### Symptom Troubleshooting Index (cont'd)

17-19

Symptom | Procedure(s) | Also check for:
Rattle or chattering (Rack rattle) |

- Check for loose steering components (tie-rod and ball joints). Tighten or replace as necessary.
- Check the steering column shaft for wobbling. If the steering column wobbles, replace the steering column assembly (see page 17-9).
- Check the rack guide adjustment (see page 17-13).
- Check the power steering pump pulley.
- If the pulley is loose, tighten it (see step 46 on page 17-34).
- If the pump shaft is loose, replace the pump (see page 17-27).

Hissing |

- Check the fluid level. If low, fill the reservoir to the proper level and check for leaks.
- Check the reservoir for leaks.
- Check for crushed inlet hose or loose hose clamp allowing air into the suction side of the system.
- Check the power steering pump shaft oil seal for leaks.

Pump noise |

- Compare the pump noise at normal operating temperature to another like vehicle (pump noise up to 2 - 3 minutes after starting the engine in cold weather is normal).
- Remove and inspect the pump for wear and damage (see page 17-28).

Squeaking | Check the power steering belt tension and adjust as necessary (see page 17-23). |
Fluid Leaks from the steering gearbox |

- Fluid leaks from the top of the valve body unit:
- Overhaul the valve body unit.
- Fluid leaks from the boot A:
  Replace the valve oil seal on the pinion shaft.
- Replace the cylinder end seal on the gearbox side.
- Fluid leaks from the boot B: Replace the left cylinder end seal.
- Fluid leaks from pinion shaft near the lower steering joint bolt: Overhaul the valve body unit.

Fluid leaks from line |

- Fluid leaks from the cylinder line connections (flare nuts):

  Tighten the connection and retest.

- Fluid leaks from a damaged cylinder lines:
  Replace the cylinder line.
- Fluid leaks from the pump outlet hose or return line fitting on the valve body unit (flair nuts):
  Tighten the fitting and retest. If it still leaks, replace the hose, the line, or valve body unit as necessary.

Fluid leaks from pump |

- Fluid leaks from the front oil seal: Replace the front oil seal.
- Fluid leaks from the power steering pump housing:
  Replace the power steering pump the leaking O-rings or seals (see page 17-28), and if necessary replace (see page 17-27).

Fluid leaks from reservoir |

- Fluid leaks from around the reservoir cap: Fluid level is too high: drain the reservoir to the proper level. Aerated fluid: check for an air leak on the inlet side of pump.
- Fluid leaks from reservoir: Check for the reservoir for cracks and replace as necessary.

Fluid leaks from pump outlet hose (high-pressure) |

- Check the fitting for loose bolts. If the bolts are tight, replace the fitting O-ring.
- Fluid leaks at the swagged joint: Replace the outlet hose.

Fluid leaks from pump inlet hose (low-pressure) | Check the hose for damage, deterioration, or improper assembly. Replace or repair as necessary. |
