Check for loose steering components (tie-rod end 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 17-25).
Check the rack guide adjustment (see page 17-30).
Check the power steering pump pulley.
If the pulley is loose, tighten it (see step 47 on page 17-21).
If the pump shaft is loose, replace the pump (see page 17-14).
Hissing noise/
foaming fluid in
reservoir
Check the fluid level. If low, fill the reservoir to the proper level
and check for leaks.
Check the reservoir for leaks.
Check for a 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.
Noise from the
power steering pump
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
17-15).
Squeaking from the
power steering pump
Check the drive belt (see page 4-43).
Fluid leaks from the
steering gearbox
Fluid leaks from the top of the valve body unit: Overhaul the
steering gearbox (see page 17-36).
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 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 the
power steering line
Fluid leaks from the cylinder line connections (flare nuts): Tighten
the connection and retest.
Fluid leaks from 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 the
power steering pump
Fluid leaks from the front oil seal: Replace the front oil seal.
Fluid leaks from the power steering pump housing: Replace the
leaking O-rings or seals (see page 17-15), and if necessary, replace
the power steering pump (see page 17-14).
Fluid leaks from the
power steering
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 the reservoir for cracks and
replace as necessary.
Fluid leaks from the
power steering 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 the
power steering pump
inlet hose
(low-pressure)
Check the hose for damage, deterioration, or improper assembly.
Replace or repair as necessary.
