Power Steering Line/Hose: Service and Repair
A: REMOVAL1. Set the vehicle on the lift.
2. Disconnect battery ground cable.
3. Lift vehicle and remove jack-up plate.
4. Remove one pipe joint at the center of gearbox, and connect vinyl hose to pipe and joint. Discharge fluid by turning steering wheel fully clockwise and counterclockwise. Discharge fluid similarly from the other pipe.
CAUTION: Improper removal and installation of parts often causes fluid leak trouble. To prevent this, clean the surrounding portions before disassembly and reassembly, and pay special attention to keep dirt and other foreign matter from mating surfaces.
5. Remove clamp E from pipes.
6. Disconnect pipe C and D from pipe (on the gearbox side).
CAUTION:
^ When disconnecting pipe C and D use two wrenches to prevent deformities.
^ Be careful to keep pipe connections free from foreign matter.
7. Lower the vehicle.
8. Remove intake duct and cleaner case.
9. Remove bolt A.
10. Disconnect pipe C from oil pump. Disconnect pipe D from return hose.
CAUTION:
^ Do not allow fluid from the hose end to come into contact with pulley belt.
^ To prevent foreign matter from entering the hose and pipe, cover the open ends of them with a clean cloth.
B: INSTALLATION
1. Tighten bolt A.
CAUTION: Visually check that hose between tank and pipe D is free from bending or twisting.
1. Connect pipe D to oil tank.
2. Connect pipe C or pressure hose to oil pump.
CAUTION: Use a new gasket.
Tightening torque: 39 Nm (4.0 kgf-m, 28.9 ft. lbs.)
3. Tighten bolt A.
Tightening torque: 13 Nm (1.3 kgf-m, 9.4 ft. lbs.)
2. Temporarily connect pipes C and D.
3. Temporarily install clamp E on pipes C and D, and tighten clamp E firmly.
CAUTION: Ensure that the letter "8" on each clamp are diagonally opposite each other as shown in figure.
Tightening torque: 7.4 Nm (0.75 kgf-m, 5.4 ft. lbs.)
4. Tighten joint nut.
Tightening torque: 15 Nm (1.5 kgf-m, 10.8 ft. lbs.)
5. Connect pipe A and B. Connect pipes A and B to four pipe joints of gearbox. Connect upper pipe B first, and lower pipe A second.
Tightening torque: 13 Nm (1.3 kgf-m, 9.4 ft. lbs.)
6. Install jack-up plate.
7. Connect battery ground cable.
8. Feed the specified fluid.
NOTE: Never start the engine before feeding the fluid; otherwise vane pump might be seized up.
9. Finally check clearance between pipes and/or hoses, as shown above.
If clearance between cruise control pump and power steering hose is less than 10 mm (0.39 inch), proceed as follows:
1. Move clamped section (A) (refer to figure above.) down to a point where pipe is close to crossmember.
Pipe-to-crossmember clearance: 10 mm (0.39 inch), min.
2. Check that clearance between cruise control pump and power steering hose is at least 10 mm (0.39 inch). If it is not, bend section (B) down until a clearance of at least 10 mm (0.39 inch) is obtained
