9. If the backlash is too small, increase the backlash using the following procedure: 1. Remove the bearing cap bolts and the bearing caps. Mark the bearing caps left or right. 2. Remove the differential case assembly with the bearing cups and the shims. Mark the bearing cups and the shims left or right. 3. Measure the thickness of left side shim pack. Measure the production shim or the shim and service spacer in 3 locations. Measure each shim separately. 4. Calculate the average of the 3 measurements for each shim. Add the average of each of the shim measurements together. Record the measurement. This is the thickness for the left side shim pack. 5. Assemble a new left side shim pack by decreasing the appropriate amount of thickness from the original left side shim pack. If the original shim is cast iron production shim, 6. Measure the thickness of right side shim pack. Measure the shim or the shim and service spacer in 3 locations. Measure each shim separately. 7. Calculate the average of the 3 measurements for each shim. Add the average of each of the shim measurements together. Record the measurement. This is the thickness for the right side shim pack. 8. Assemble a new right side shim pack by increasing the appropriate amount of thickness to the original right side shim pack. If the original shim is cast iron production shim,
