a. Remove the bolt.

b. Using pliers, pull out the drive pinion cap.
c. Remove the O-rings from the cap.

7. MEASURE DRIVE PINION PRELOAD
Using a torque meter, measure the drive pinion preload.
Preload (at starting):
Roused bearing 0.5 - 0.8 Nm (5 - 8 kgf-cm, 4.3 - 6.9 inch lbs.)
The total preload measured in step 1 minus the drive pinion preload equals 0.1 - 0.2 Nm (1.3 - 2.0 kgf-cm, 1.1 - 1.7 inch lbs.). If the result is not within this specification, the side bearing preload is bad.
