Mechanical and Automotive 10, A20, B20, A30, B30

(a)	Identify and follow safe work practices (e.g., be aware of the dangers of welding or heating steering linkage components and be aware of spring tension) when working with automotive suspension systems, including maintaining a clean and organized work area.
(b)	Describe how different types of springs (e.g., leaf, coil, torsion bar and air) are used in automotive suspension systems.
(c)	Describe the operation of suspension components (e.g., shocks, struts, sway bars and ball joints) and their effects on vehicle stability.
(d)	Inspect and evaluate suspension component condition for damage, corrosion, wear and excessive play.
(e)	Diagnose and perform repair procedures (e.g., remove and replace parts in pairs, disassemble and reassemble a strut and spring assembly and replace ball joints) on automotive suspension systems using appropriate equipment (e.g., ball joint press and strut spring compressor).
(f)	Make preliminary wheel alignment adjustments after suspension components (e.g., struts and control arms) have been replaced.
(g)	Follow correct torqueing procedures for all suspensions systems fasteners and discuss how improper torqueing can be a safety issue.
