2. disable and enable supplemental restraint system (SRS);
3. remove and replace steering wheel, center/time supplemental restraint system (SRS) coil
(clock spring);
4. diagnose steering column noises, looseness, and binding concerns (including tilt
mechanisms) and determine necessary action;
5. inspect steering shaft universal-joint(s), flexible coupling(s), collapsible column, lock
cylinder mechanism, and steering wheel, and perform necessary action;
6. remove and replace manual or power rack and pinion steering gear, and inspect
mounting bushings and brackets;
7. inspect and replace manual or power rack and pinion steering gear inner and outer tie
rod ends (sockets) and bellows boots;
8. inspect power steering fluid levels and condition, flush, fill, and bleed power steering
9. diagnose power steering fluid leakage, inspect and replace power steering hoses and

necessary action;
22. check and adjust front and rear wheel camber, caster, and toe, center steering wheel,
check toe-out-on-turns, SAI and included angle, and rear wheel thrust angle;
23. inspect and diagnose tire wear patterns, wheel/tire vibration, shimmy, noise, tire pull
(lead) problems check and determine necessary action;
24. rotate and balance wheel and tire assemblies and adjust air pressure according to
manufacturer’s recommendations;
