We Are Here For You Now and in the Future.

Drivers are the backbone of our country and keep us moving forward. As customers rely on you to deliver, Peterbilt Parts and Service dealers can make sure your truck is in ready condition when it hits the road.

Peterbilt Parts and Service dealers across the country are stocked and available to help with all your service and maintenance needs, when you need them. Here is checklist of what to inspect to ensure your truck is running at its best.

BRAKES

Check for missing, non-functioning, loose, contaminated or cracked parts on the brake system and check for S-cam flipover. Be alert for audible air leaks around brake components and lines. Make sure that slack adjusters are the same length (from center of S-cam to center of clevis pin) and the air chambers on each axle are the same size. 

COUPLING DEVICES

Check the safety devices (chains/wire rope) for sufficient strength, missing components, improper repairs and devices that are incapable of secure attachment.

FUEL AND EXHAUST SYSTEMS

Check your fuel tanks for loose or missing caps and signs of leaking fuel below the tanks. For exhaust systems, look for unsecured mounting; leaks beneath the cab; exhaust system components in contact with electrical wiring or brake lines and hoses; and excessive carbon deposits around seams and clamps. 

FRAME, VAN AND OPEN-TOP TRAILERS

Frames should be free of corrosion fatigue, cracks and loose or missing cross-members. For vans and open-top trailer bodies, inspect upper rails, roof bows and side posts for buckling, cracks or ineffective fasteners. On the lower rail, check for breaks, sagging floor, rail or cross members; or broken with loose or missing fasteners at side post adjacent to the crack.

LIGHTING

Inspect all required lamps for proper color, operation, mounting and visibility.

CARGO

Check tail board security, end gates and rear doors. Additionally, make sure you have the proper number and size of cargo securement devices for your load and the tie down anchor points have no deformation or cracking.

STEERING

Check your steering lash to ensure you are within the allowable lash (or free play) distance. The allowable distance changes with the diameter of the steering wheel.

SUSPENSION

Inspect for indications of misaligned, shifted, cracked or missing springs; loose shackles; missing bolts; unsecured spring hangers; and cracked or loose U-bolts. Also, check any unsecured axle positioning parts and for signs of axle misalignment.

TIRES, WHEELS, RIMS AND HUBS

Check tires for proper inflation, cuts and bulges, regrooved tires on steering axle, tread wear and major tread groove depth. Inspect wheels and rims for cracks, unseated locking rings, and broken or missing lugs, studs or clamps. On the hubs, look for lubricant leaks, missing caps or plugs, misalignment and positioning, and damaged, worn or missing parts.
