Research vehicle drive train, suspension, and steering service information, including fluid type, vehicle service history, service precautions, and technical service bulletins.

Identify suspension, steering system, and drive train components, transmission type, and configuration.

Inspect and adjust clutch, clutch brake, linkage, cables, levers, brackets, bushings, pivots, springs, clutch safety switch (including push-type and pull-type), pedal height, pedal travel, clutch master cylinder fluid level, clutch master cylinder, slave cylinder, lines, and hoses for leaks and damage to determine needed action.

Inspect transmission shifter, linkage, transmission mounts, insulators, mounting bolts, transmission leakage, transmission breather, transmission oil filters, coolers, speedometer components, function of reverse light, neutral start, and warning device circuits and determine needed action.

Remove and replace transmission cover plates, gaskets, seals, and cap bolts and inspect seal surfaces and vents to determine needed action.

Check transmission fluid level and condition and determine needed action.

Inspect, service, and replace driveshafts, slip joints, yokes, drive flanges, support bearings, universal joints, boots, seals, and retaining/mounting hardware and check phasing of all shafts.

Perform drive axle inspection including fluid leaks, drive axle housing assembly, shaft, cover plates, gaskets, seals, vent/breather, magnetic plugs, drive axle fluid, and drive axle filter to determine needed action.

Inspect air-operated power divider (inter-axle differential) assembly including diaphragms, seals, springs, yokes, pins, lines, hoses, fittings, controls, and drive axle shafts to determine needed action.

Remove and replace wheel assembly, check rear wheel seal and axle flange for leaks, and determine needed action.

Disable and enable supplemental restraint system (SRS) and verify indicator lamp operation.

Check steering wheel for free play, binding, and proper centering, inspect and service steering shaft U-joint(s), slip joint(s), bearings, bushings, and seals, phase steering shaft, check operation of tilt and telescoping steering column, and check cab mounting.

Inspect steering pump and gear unit, including operation, mountings, lines, hoses, fluid level and condition, service filter, and inspect system for leaks.

Flush and refill power steering system and purge air from system.

Inspect steering linkage components and lubricate as needed.

Inspect suspension system to determine needed action, including shock absorbers, shock bushings, shock brackets, shock mounts, leaf springs, center bolts, clips, pins, shackles, U-bolts, insulators, spring bracket, spring mounts, axle, axle aligning devices, axle bushings, axle mounts, axle shims, tandem suspension equalizer components, air suspension pressure regulator components, ride height, air springs, mounting plates, springs, suspension arms, radius rods, track bars, stabilizer bars, and torque arms.

Describe the aspects of alignment angles.

Inspect wheel and tire condition to identify tire wear patterns and tread depth.

Verify and record tire matching including diameter and tread, inspect valve stem and cap, and set tire pressure.

Identify wheel and tire problems, including vibration, shimmy, pounding, and hop (tramp).

Check wheel mounting hardware including removal and installation of wheel/tire assemblies (steering and drive axle), and torque fasteners to manufacturer’s specification using torque wrench.

Inspect, service, and adjust fifth wheel, pivot pins, bushings, locking mechanisms, mounting hardware, air lines, fittings, frame and frame members, frame hangers, brackets, and cross members for cracks, breaks, corrosion, distortion, elongated holes, looseness, or damage.

Check pintle hook and mounting (if applicable).
