8. Insert a suitable pry bar and move the knuckle up and down while you tighten bolts (12). Tighten bolts (12) until there is no end play. Use a suitable feeler gauge and measure the clearance between pin assembly (13) and the knuckle. Measure the clearance at several points and average the measurement. Use shims (14) that equal the measurement in order to achieve Zero end play.

9. Remove pin assembly (13). Apply Tooling (D) to the surface of pin assembly (13). Install pin assembly (13), the correct shims (14), and bolts (12). Tighten bolts (12) to a torque of 300 N·m (221 lb ft).
