Hard Steering Check the power assist (see page 17-4). Is the power assist more than 29 N (3.0 kgf, 6.6 lbf)? YES - Go to step 2. NO - Power assist is OK. Measure steady-state fluid pressure from the pump at idle (see page 17-21). Is the pressure 1,500 kPa (15 kgf/cm2, 213 psi) or less? YES - Go to step 3. NO - Go to step 7. Measure the pump relief pressure at idle (see page 17-21). Is the pressure 7,600 - 8,300 kPa (78 - 85 kgf/cm2, 1,110 - 1,210 psi) or less? YES - Go to step 4. NO - Go to step 8. With a spring scale, measure the power assist in both directions, to the left and to the right. Are the two measurements within 2.9 N (0.3 kgf, 0.66 lbf) of each other? YES - Go to step 5. NO - Go to step 9. Measure the fluid pressure (see page 17-21) with shut-off and pressure gauge valves open, while turning the steering wheel fully to the left and fully to the right. Is the pressure 7,600 - 8,300 kPa (78 - 85 kgf/cm2, 1,110 - 1,210 psi) or less? YES - Go to step 6. NO - Faulty gearbox.

Adjust the rack guide (see page 17-13), and retest. Is the steering OK? YES - Repair is completed. NO - Faulty gearbox. Check for feed and return lines between the pump and the gearbox for clogging and deformation. Are the lines clogged or deformed? YES - Repair or replace the lines. NO - Faulty valve body unit. Check the pressure control valve (see page 17-29). Is the pressure control valve OK? YES - Faulty pump assembly. NO - Faulty pressure control valve. Check the cylinder lines for deformation (see page 17-22). Are the lines deformed? YES - Replace the lines. NO - Go to step 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? YES - Replace the rack shaft or readjust the rack guide. NO - Faulty valve body unit.
