Inspection Guide
5. Air Suspension (if equipped): Check for air leaks, loose
components, and damage to air bag. Inspect stabilizer
bar for worn, loose, or damaged components.
6. Brake Chamber and Hoses: Check to see that the
brake chambers are not cracked or damaged, and are
securely mounted. Check for broken, loose or missing
parts. Check for cracked, worn or frayed hoses, and for
secure couplings.
7. Slack Adjuster: Check slack adjuster and chamber push
rod travel. When pulled by hand, push rod should not
move more than approximately 1 inch. Angle between
push rod and adjuster arm should be approximately 90
degrees when brakes are applied.
8. Brake Lining and Drum: With brakes released, check
to see that brake linings (where visible) are not
worn excessively thin (less than 1/4 inch [6 mm]) or
contaminated by lubricant.
9. Tire: Check tread depth, tire inflation and note if tread
is evenly worn. Minimum tread depth is 4/32 inch on
steering tires. Look for cuts or other damage to the tread
or sidewalls. Check for missing, broken or damaged
valve cap and stem.
10. Wheel and Lug Nuts: Check for damaged or bent wheel.
Check to see that all lug nuts are present and not loose
(look for rust trails around nuts). Ensure that no cracks
or damage are present at wheel mount holes.
11. Hub: Check for obvious leaks on outside or inside of
wheel. Verify correct oil level in hub.
12. Steering Linkage: Inspect connecting links, arms, rods,
and steering intermediate shaft for worn, damaged,
loose, or missing components.
