NOTE:
Ensure power steering fluid is at correct level and normal operating temperature.
- Install Power Steering Analyzer (D79L-33610-A) or equivalent (i.e., 0-2000 psi pressure gauge and valve assembly) between power steering pump and high pressure line. Ensure analyzer gauge gate valve is completely open. Remove horn button/pad from steering wheel.
- Attach an INCH-lb. torque wrench to steering wheel nut. Center steering wheel. Set engine idle to 1000 RPM. Using torque wrench, rotate steering wheel to each side of center to obtain gauge reading of 250 psi (17.5 kg/cm2 ) in each direction.
- Torque wrench reading should be equal in both directions when gauge is at 250 psi (17.5 kg/cm2 ). If difference between torque readings exceeds 6 INCH lbs. (.68 N.m), remove steering gear unit. Replace worm shaft/valve sleeve Teflon sealing rings. Replace control valve housing assembly. See Figure .
