power steering
system/foaming
fluid
Noise from the
power steering
pump
Squeaking from

steering pump
Fluid leaks from
the steering
gearbox
Procedure(s)
1. Check when the noise occurs:
• If the noise is heard during the first 2 3 minutes after starting
the engine in cold weather, this is normal.
• If the noise is heard when the wheel is turned with the vehicle
stopped, this is normal due to the fluid pulsation.
2. Check for air bubbles in the power steering fluid, leak on inlet
side of pump.
3. Check for particle contamination of fluid and a restricted filter in
the reservoir.
4. Check for the high-pressure hose touching the subframe or body.
5. Check for automatic transmission torque converter noise.
1. Check for loose steering components (tie-rod and ball joints).
Tighten or replace as necessary.
2. Check the steering column shaft for wobbling. If the steering
column wobbles, replace the steering column assembly
(see page 17-28).
3. Check the power steering pump pulley on the shaft comp. for
damage and deterioration, replace the shaft comp. if necessary
(see page 17-17).
4. Check the rack guide adjustment (see page 17-35).
• Check the fluid level. If low, fill the reservoir to the proper level
and check for leaks (see page 17-14).
• Check the reservoir for leaks.
• Check for crushed inlet hose or loose hose clamp allowing air into
the suction side of the system (see page 17-15).
• Check the power steering pump shaft oil seal for leaks.
• Compare the pump noise at normal operating temperature to
another like vehicle (pump noise during the first 2 3 minutes
after starting the engine in cold weather is normal).
• Remove and inspect the pump for wear and damage (see page
17-16).
Check the drive belt (see page 4-31).
• Fluid leaks from the top of the valve body unit. Overhaul the valve
body unit (see step 23 on page 17-48).
• Fluid leaks from the driver's side boot. Replace the valve oil seal
on the pinion shaft. Replace the cylinder end seal on the gearbox
side.
• Fluid leaks from the passenger's side boot. Replace the cylinder
end seal on the cylinder side.
• Fluid leaks from pinion shaft near the lower steering joint bolt.
Overhaul the valve body unit (see step 23 on page 17-48).
• Fluid leaks from the steering damping valve covers on the valve
body unit. Replace the valve housing.
