N MANUAL STEERING STEERING WHEEL AND COLUMN Obtain the code number and deactivate the audio anti- theft system before disconnecting the battery. (Refer to section T.) On-vehicle Inspection Steering wheel play If the play exceeds specification, either the steering joints are worn or the backlash of the steering gear is excessive. With the wheels in the straight-ahead position, gently turn the steering wheel to the left and right and verify that the play is within specification. Play: 0--30mm (0-1.18 in) Looseness or play of steering wheel Move the steering wheel in directions a, 0, and @ to check for column bearing wear, steering shaft joint play, steering wheel looseness, and column looseness. Steering wheel effort 1. On level ground, jack up the front of the vehicle and sup- port it on safety stands. 2. Turn the steering wheel fully to the left and right at least 5 times. 3. Move the steering wheel to put the wheels in the straight ahead position. 4. Attach a pull scale to the outermost point of the steering wheel spoke. Then, starting with the wheels in the straight-ahead posi- tion, measure the effort required to turn the steering wheel to the left and to the right. Steering wheel effort: 5.0--29 N (0.S3.0 kgf, 1 .l--6.6 Ibf) (during one turn of steering wheel) 5. If not within specification, check the following: rotation starting torque of pinion, rotation torque of each ball joint, and steering joints. Gartner Banana

ENGINE SPEED SENSING POWER STEERING N THERMOMETER GAUGE (50"--60°C (1 22-1 40°F)) / THERMOMETER GAUGE (50"--60°C {I 22-140°F)) / Fluid pressure 1. Assemble the SST as shown in the figure. Tightening torque: 40-49 N-m i4.0-5.0 kgf-m, 2%--36 ft.lbf) 2. Mark both hose connections to ensure that the hose is reinstalled in its original position. 3. Disconnect the pressure hose from the oil pump. Attach the SST. 4. Bleed the air from the system. (Refer to page N-21.) 5. Open the gauge valve fully. Start the engine and turn the steering wheel fully left and right to raise the fluid temper- ature to 50-60°C (122-140°F). Caution Do not let the valve stay closed for more than 5 seconds. The increase in fluid temperature will damage the oil pump. 6. Close the gauge valve completely. Increase the engine speed to 1,000-1,500 rpm and measure the fluid pres- sure generated by the oil pump. If the pressure is not within specification, replace the oil pump assembly. Oil pump fluid pressure: 7,601--8,335 kPa (77.5--85.0 kgf/cm2, 1 ,I 03-1,208 psi) 7. Open the gauge valve fully and increase the engine speed to 1,000-1,500 rpm. Gartner Banana

N ENGINE SPEED SENSING POWER STEERING Caution Never hold the steering wheel to the extreme left or right for more than five seconds with the engine running. This could damage the power steering d pump- 8. Turn the steering wheel fully to the left and right and measure the fluid pressure generated by the gear hous- ing. If the pressure is not within specification, replace the gear housing assembly. Gear housing fluid pressure: 7,601--8,335 kPa (77.545.0 kgflcm2, 1,103-1,208 psi) 9. Remove the gauge set. Install and tighten the pressure hose to the specified torque. Tightening torque: 3247 N.m (3.24.8 kgf.m, 24--34 ft.lbf} 10. Bleed the air from the system. (Refer to page N-21.) STEERING WHEEL AND COLUMN Obtain the code number and deactivate the audio anti- theft system before disconnecting the battery. (Refer to section T.) On-vehicle Inspection -1 Steering wheel effort 1. With the vehicle on a hard, level surface, put the wheels in the straight-ahead position. 2. Start the engine and warm the power steering fluid to 50--60°C (1 22-1 40°F). 3. With the engine running at idle, attach a pull scale to the outermost point of the steering wheel spoke. Then, starting with the wheels in the straight-ahead posi- tion, measure the effort required to turn the steering wheel to the left and to the right. Steering wheel effort: 2635 N (2.63.6 kgf, 5.3-7.9 Ibf) (during one turn of the steering wheel) 2 4. If not within specification, check the following: fluid level, air in system, fluid leakage at hose or connections, func- tion of oil pump and steering gear, and tire pressure. Gartner Banana

ENGINE SPEED SENSING POWER STEERING N STEERING GEAR AND LINKAGE Removal / Installation 1. Turn the wheels to the straight-ahead position. 2. Loosen the wheel lug nuts. 3. On level ground, jack up the front of the vehicle and support it on safety stands. 4. Remove the wheels. Note Turning the steering wheel while the steering gear is removed will make reinstallation difficult. Do not turn the steering wheel while the steering gear is removed. If the steering wheel is turned in that condi- tion, the clockspring connector may have to be adjusted. (Refer to section T.) 5. Remove in the order shown in the figure, referring to Removal Note. 6. With the wheels in the straight-ahead position, install in the reverse order of removal. 7. Tighten all necessary bolts and nuts to the specified torque. 8. After installation: (1) Check for fluid leakage. (Refer to page N-22.) (2) Bleed air from the system. (Refer to page N-21.) (3) Adjust the front wheel alignment. (Refer to section R.) 1.

P BRAKE SYSTEM Removal / Installation 1. When disconnecting the flexible hose and brake line, remove the clip after loosening the flare nut by using the SST. > 2. When connecting the flexible hose, do not over tighten or twist it. 3. Verify that the hose does not contact other parts when the vehicle bounces or when the steering wheel is turned all the way to the left or right. 4. Modify the brake pipe tightening torque to allow for a torque wrench-SST combination. (Refer to section GI) "Torque Formulas". 5. Tighten the flare nut by using the SST. Tightening torque: 13-22 N.m (1 3-2.2 kgf-m, %&-I 6 ft-lbf} 6. Bleed the air from the brake system. BRAKE FLUID Inspection Check the fluid level in the reservoir. It should be between MAX and MIN. If the fluid level is extremely low, check the brake system for leaks. J Fluid specification: FMVSS 11 6: DOT-3 Replacement 1. Follow the procedure outlined in Air Bleeding. (Refer to page P-7.) 2. Continuity air bleeding and replacing the brake fluid until only clean fluid is seen. 3. Fill the reservoir to MAX. Gartner Banana
