Inspection Guide
5. Wheel and Wheel Nuts: Check for damaged or bent
wheel. Check to see that all wheel nuts are present and
not loose (look for rust trails around nuts). Ensure that
no cracks or damage are present at wheel mount holes.
6. Tires: Check tread depth, tire inflation and note if tread
is evenly worn. Minimum tread depth is 2/32 inch on all
drive tires. Look for cuts or other damage to the tread
sidewalls. See if valve caps and stems are missing,
broken or damaged. Check dual spacing to ensure that
dual wheels are evenly separated, and that tires are not
touching one another.
7. Hub: Check for obvious leaking on outside or inside of
wheel. Inspect axle flanges and wheel seals for leaks
and loose mounting hardware or broken items. Check
lube level, if equipped with sight glass.
8. Spring Suspension: Check condition of spring for
cracks, breaks, or shifting. Inspect spring hanger
fasteners, shackles, U-bolts, and nuts for wear, damage,
and tightness.
9. Torque Rods and Shock Absorbers: Check to see that
torque rods are not cracked, broken, or missing. Check
shock absorbers for cracks or leaks. There should be
no missing or broken mounting bolts or worn bushings.
10. Air Suspension (if equipped ) Check for air leaks, loose
components, and damage to air bag. Inspect ride height
valve and linkage for damage.
• Air Lines and Wiring: Check air Lines and electrical wiring
for proper security, damage, and chafing. Listen for audible
air leaks.
