Procedure 3 & 4: Tires and Steering Gear Valve Off Center
Procedure 3: Tires1. Spin the front tires to make sure the front hubs are unlocked. If the hubs are unlocked, the axle shafts will not rotate with the wheels.
2. Measure tire circumference of all four tires. Put the two closest circumference tires on the rear axles. Tire pressure must be equal on all tires.
Procedure 4: Steering Gear Valve Off Center
1. Lift the front wheels off the ground. The vehicle should be raised so that there is no interference with the steering linkage.
2. With the wheels in a straight position, start the engine and observe any steering wheel or linkage movement when the engine is started. If movement is observed, continue with this procedure.
3. Spin the front tires to make sure that the front hubs are unlocked. If the hubs are unlocked, the axle shaft will not rotate with the wheels.
4. Stop engine and install a 0-13,789 kPa (0-2000 psi) pressure gauge (Tool D79L-33610-A, Power Steering Analyzer) in the pressure line between the power steering pump outlet port 1, and the steering gear inlet port. Make sure the gauge on the valve is fully open.
5. Check the fluid level in the power steering fluid reservoir. Add Premium Power steering Fluid or equivalent if necessary.
6. Start the engine and turn the steering wheel from stop-to-stop to bring the steering lubricant to normal operating temperature.
7. Turn off the engine and re-check the fluid level. Add Power steering fluid, Type F Automatic Transmission Fluid (M2CC33F or equivalent if necessary.
8. With the engine running at approximately 1000 rpm and the steering wheel centered, attach an in.lb. torque wrench to the steering wheel nut.
9. Apply sufficient torque in each direction to get a reading on the pressure gauge of 1723 kPa (250 psi).
10. The torque wrench readines in both directions should be the same. If the difference between the readings exceeds 6 in.lb., remove the steering gear and replace the shaft and control assembly. Refer to Section N-02 of the Workshop Manual for details.
11. Remove the pressure gauge installed in step 4.
