Rotate the wheel for several revolutions and torque the bolts again. Continue the sequence of rotating the wheel and torquing the bolts until the bolt torque does not change.
Use depth micrometer (E) in order to measure the depth through the small gauge holes (3). Find the average value of the three measurements.
Subtract the thickness (X) of the retainer from the value that was found in Step 14. This difference is the clearance between the end of the spindle and the retainer.
Add the value from Table 3 below to the value that was found in Step 15. The result is the correct thickness of shims that is needed.

( 1 ) Add this value to the value that was found in Step 15.
Remove the bolts that fasten the retainer to the spindle and remove the retainer.
Install the appropriate thickness of shims that was found in Step 16. Then, fasten the retainer to the spindle with all of the bolts. Tighten the bolts evenly to the torque that is given in Table 4 below. Turn an additional 120 10°.

Note: This procedure can be performed with the tire and rim in place.
Use an outside micrometer in order to measure thickness (X) of the retainer. Take one measurement at each of the three small gauge holes (3). Determine the average plate thickness from these measurements.
Put oil on the wheel bearings, brake discs, and plates. Put the wheel assembly and bearings in position on the spindle.
Install the hub and ring gear.
Install the retainer without shims. In order to fasten the retainer to the spindle, install the correct number of bolts from Table 5 below. Equally space the bolts. Install the first bolt of the equally spaced bolts at the top of the spindle. Refer to Illustration 4.
