Hard steering

  1. Check the power assist (see Power Assist Check  )

    Is the power assist more than 29 N (3.0 kgf, 6.6 lbf)? 

    1. YES  - Go to step 2.
    2. NO  - Power assist is OK.
  2. Measure steady-state fluid pressure from the pump at idle with T/N 07406-0010001 (see step 9 on Pump Pressure Test with T/N 07406-0010001  ) or T/N 07406-001000A (see step 8 on Pump Pressure Test with T/N 07406-001000A  ).

    Is the pressure 1,500 kPa (15 kgf/cm2, 213 psi) or less? 

    1. YES  - Go to step 3.
    2. NO  - Go to step  7.
  3. Measure the pump relief pressure at idle with T/N 07406-0010001 (see step 10 on Pump Pressure Test with T/N 07406-0010001  ) or T/N 07406-001000A (see step 9 on Pump Pressure Test with T/N 07406-001000A  ).

    Is the pressure 8,300-8,800 kPa (85-90 kgf/cm2, 1,210-1,280 psi) or less? 

    1. YES  - Go to step 4.
    2. NO  - Go to step  8.
  4. With a spring scale, measure the power assist in both directions, to the left and to the right.

    Are the two measurements within 5.0 N (0.51 kgf, 1.12 lbf) of each other? 

    1. YES  - Go to step 5
    2. NO  - Go to step  9
  5. Measure the fluid pressure with T/N 07406-0010001 (see step 11 on Pump Pressure Test with T/N 07406-0010001  ) or T/N 07406-001000A (see step 10 on Pump Pressure Test with T/N 07406-001000A  ) with both pressure gauge valves open (if so equipped), while turning the steering wheel fully to the left and fully to the right.

    Is the pressure 8,300- 8,800 kPa (85-90 kgf/cm2, 1,210-1,280 psi) or less? 

    1. YES  - Go to step 6.
    2. NO  - Replace the gearbox.
  6. Adjust the rack guide (see Rack Guide Adjustment  ), and retest.

    Is the steering OK? 

    1. YES  - Repair is completed.
    2. NO  - Replace the gearbox.
  7. Check for feed and return lines between the pump and the gearbox for clogging and deformation.

    Are the lines clogged or deformed? 

    1. YES  - Repair or replace the lines.
    2. NO  - Replace the valve body unit.
  8. Check the flow control valve (see Pump Overhaul  ) for smooth movement and leaks.

    Is the flow control valve OK? 

    1. YES  - Replace the pump assembly.
    2. NO  - Replace the flow control valve.
  9. Check the cylinder lines A and B for deformation (see Steering Gearbox Overhaul  )

    Are the A or B lines deformed? 

    1. YES  - Replace the lines.
    2. NO  - Go to step 10.
  10. Check for a bent rack shaft or misadjusted rack guide (too tight)

    Is the rack shaft bent or the rack guide adjusted too tight? 

    1. YES  - Replace the rack shaft or readjust the rack guide.
    2. NO  - Replace the valve body unit.
