acceptable.
(1)
Inspect axles and suspension. Inspect axle assembly for cracked or dented housing; bent,
missing, or broken components; loose or missing fasteners; broken or missing lubrication
fittings; and lubricant leaks.
(2)
Inspect tires and wheels for condition (excessive wear, cuts, or foreign objects). Check that
each tire has 3/16 inch or more of tread remaining, and is in good serviceable condition.
Check that all tires on a vehicle are matched to provide proper performance and
approximately equal life. Tires will not show evidence of cupping or chunking. Check that
tires do not have cuts or cracks and that the air inflation pressures are equal. Inspect for
rubber separation or bulges on tire sidewalls. Inspect wheels for missing lug nuts.
Determine whether wheels are free of cracks, breaks, and damaged mounting holes.

Inspect tow bar speed/direction control assembly to determine if it works freely; inspect the
dead-man switch for damage and check for loose or missing components inside and external
of housing cover.

indicating improper operation. Verify that the hand or parking brake is complete with all

terminals, loose or missing brush covers, and corrosion or contamination.
