4. Install a lever under the top lug of knuckle (11) and lever up the knuckle. Tighten bolts (5) until there is no vertical play in the knuckle. The knuckle must still be free to rotate.

5. Use a feeler gauge to establish clearance (K) at two opposite positions. Calculate the average clearance from the two measurements. Add 0.4 ± 0.1 mm (0.015 ± 0.003 inch) to the average measurement. This is the thickness of the shims that are required.

   Note: Shims are available in the following thicknesses: 0.15 mm (0.006 inch), 0.20 mm (0.008 inch) and 0.50 mm (0.020 inch).
