• Because the components are safety-critical, they have to meet rigorous strength (torque loading) and cyclic fatigue requirements.

• The components have stringent dimensional tolerances on the machined bores and slots for fit and assembly.

• The lower components must also resist corrosion and abrasion from slush, snow, deicing agents, and gravel on the operator's shoes.
