Measure steering gear meshload. Reference the appropriate Workshop Manual for the procedure for measuring meshload.
a.
If it is less than 0.45 Nm (4 lb-in), reset to 0.56-0.68 Nm (5-6 lb-in).
NOTE:
THE MESHLOAD MEASUREMENT IS THE AMOUNT OF THE TORQUE INCREASE THAT THE TORQUE WRENCH SHOWS AS THE
STEERING WHEEL IS ROTATED THROUGH THE CENTER OF ITS TRAVEL (I.E., IF THE STEERING WHEEL TORQUE TO ROTATE IS
MEASURED AT 0.45 Nm (4 LB-IN) ON THE ENDS, AND THEN IT MEASURES 1.13 Nm (10 LB-IN) AS IT IS ROTATED THROUGH THE
CENTER, MESHLOAD 0.68 Nm (6 LB-IN). MESHLOAD = CENTER - END (1.13 Nm - 0.45 Nm = 0.68 Nm OR 10 LB-IN - 4 LB-IN = 6 LB-IN
OF MESHLOAD).
b.
Once meshload is OK, procedure is complete. Return vehicle to customer.
