The purpose of these procedures is to pinpoint the location
of the leak. In some cases, the leak can be located easily. Seepage-type leaks
may be more difficult to locate. Use the following method to locate seepage
leaks:
- With the engine OFF, wipe the power steering system dry.
- Check the power steering fluid level. Add power steering fluid
if necesary. Refer to
Checking and Adding Power Steering Fluid
- Start the engine.
- Have someone else turn the steering wheel from stop to stop several
times. Do not hold the steering wheel in a stop position for any length of
time or damage to the power steering pump could result.
- Locate the power steering fluid seepage leak.
- Repair the power steering fluid leak.
Power Steering Gear Leak Diagnosis
- Tighten the fittings (1) to 27 N·m (20 lb ft).
Replace the O-ring seals (1) if leakage persists.
- Replace the dust and stub seals (2).
- Replace partial gear assembly if leakage is observed between torsion
bar and stub shaft (3).
- Replace partial gear assembly if leakage is observed at the driver
side (4) and is not affected by the direction of turn.
- Replace partial gear assembly if leakage is observed at the housing
end (5) and spurts when bottomed in left turn.
- Replace partial gear assembly if leakage is observed at these
points (6).
Power Steering Pump Leak Diagnosis
- Replace drive shaft seal (5). Ensure that the driveshaft is clean
and free of pitting or grooves in seal contact area.
- Seat ball in the housing with blunt punch (4).
- Tighten fitting (3) to 75N·m (55 lb ft). Replace
O-ring seal (3) if leakage persists.
- Tighten hose fitting (2) nut to 27N·m (20 lb ft).
If leakage persists replace O-ring seal (2).
- Replace the O-ring seal if leakage persists (1).
- Replace the O-ring seal (6).
