  5. Use Tooling (B) and two suitable lifting devices to position steering arm (1) onto spindle (5). The weight of steering arm (1) is approximately 309 kg (681 lb). Install three of bolts (3) that are separated by 120 degrees. Remove Tooling (B). Tighten three of bolts (3) to a torque of 203 ± 27 N·m (150 ± 20 lb ft). Use Tooling (F) to measure the gap between the end of suspension cylinder (6) and the surface of steering arm (1). Loosen three of bolts (3). Install Tooling (B) and two suitable lifting devices. Remove three of bolts (3). Remove steering arm (1).
