Clearance - I am checking the space between the rear of the tractor frame and the landing gear to verify that it is large enough so the landing gear will not hit the frame during tight turns.

Landing Gear - I am checking the landing gear of the trailer for secure mounting and missing, damaged, or broken parts. I am checking that it is fully raised and the handle is secured.

Trailer Sides - I am checking the trailer sides for damage and that all lights and reflective tape are present and not broken.

Frame - I am checking the trailer for cracks, broken welds, holes, or other damage to longitudinal frame member, cross members, box or floor.

 

Splash Guards - I am checking that the splash guards are securely mounted and not damaged.

Doors - I am checking the doors and hinges for damage and to see that they open, close and latch properly from the outside.

DOT bumper - I am checking the DOT bumper for secure mounting and no missing, damaged, or broken parts.

Plate - I am checking that the license plate is present and properly secured.

Trailer

Suspension - I am checking the spring mounts for cracked or broken spring hangers, missing or damaged bushings, broken or missing bolts, u-bolts or other axle mounting parts. I am checking at each point where they are secured to the frame and axle.

If leaf springs -I am checking for missing, shifted, cracked or broken leaf springs. If coil springs - I am checking for broken or distorted coil springs. If equipped with torsion bars or torque arms - I am checking to see that the torsion bars and/or torque arms are securely mounted and are not damaged. If air ride suspension - I am checking the air ride suspension for damage or leaks.

Shock Absorber - I am checking the shock absorber to see that it is securely mounted, the bushings are good, and it is not bent, damaged, or leaking.

Identify the following items being checked as inside or outside (on duals) and on which axle.

Hose - I am checking the hose and couplings to the brake chamber for the left side of the front tandem axle for any cracks, wear or leaks.

Brake Chamber - I am checking the brake chamber for the left side of the front tandem axle for air leaks, cracks, and missing, damaged, or broken parts; and that it is securely mounted.

Slack adjusters - With the wheels chocked and brakes released I am checking that the slack adjuster does not move more than 1 inch when pulled. If greater than 1 inch, the brakes will apply unevenly and should be adjusted. I am checking for any missing, damaged, or broken parts. The angle between the pushrod and adjuster arm should be slightly over 90 degrees with the brakes released and slightly less than 90 degrees with the brakes applied.

Sliding Tandem - (If you have a sliding tandem) I am checking the sliding tandem to make sure that the locking pin is in place, is not damaged and the safety is engaged.

Brake shoes and linings - I am checking for grease or oil on the brake linings, if they are worn, and if there are any missing, damaged, or broken parts.

Brake Drum - I am checking the left side front tandem axle brake drum for cracks, dents, or holes. If the brake drum has a crack 1/2 the width of the friction area it will put the truck out of service until replaced.

Wheels - I am checking the inside wheel on the front tandem axle to see if it is bent, damaged, or cracked. I am checking for any welds which are not factory. These are not allowed and would put the truck out of service if found. I am checking the outside wheel on the front tandem axle to see if it is bent, damaged, or cracked. and there are no welds which are not factory. I am checking the space between the dual wheels and tires for misalignment and that there is no debris between them.

Lug Nuts - I am checking the lug nuts for missing nuts and tightness. Rust around the nut may indicate they may be loose. Nuts should be checked with a lug wrench.

Hub Seal - I am checking the hub seal for leaks. I am checking level of the oil (if seal is transparent).

Repeat Hose through Hub Seal inspections for the rear tandem axle.

That completes the Trailer section, close the hood and go to the Inside Section.
If testing; at the completion of this section, say "I will now inspect the right side just as I did the left, would you like me to start at the front or rear?" If you get lucky, the examiner will be tired of hearing you repeat it all and knows that you can do it again. They may tell you to skip it. If not lucky, repeat everything again on the right side with the appropriate location changes. Don't forget the steering axle. If not testing, check it all. Your life and that of others depends on it.
