Road safety is a top priority for all truck drivers, and the truck´s suspension system plays a crucial role in this regard. Regular and thorough inspection of the suspension not only ensures the driver´s safety but also helps avoid costly repairs and potential penalties for non-compliance. In California, the Federal Motor Carrier Safety Administration (FMCSA) and the Department of Motor Vehicles (DMV) require that all commercial vehicles, including trailers, meet strict maintenance standards to prevent accidents and ensure safe transportation.

Why is it crucial to inspect the suspension?

Truck units often suffer from chronic neglect, operating for long periods without proper inspections. When a unit shows signs of suspension issues, it must be addressed immediately. Conducting regular pre-trip inspections can prevent major problems, such as loss of vehicle control.

Basic Steps for an Effective Inspection

1. Pre-Trip Inspection: Start by checking each joint and part of the suspension, especially if you´ve noticed recent issues or noises while driving. Report any concerns to your mechanic for prompt repair and thorough inspection of the unit.

2. Comprehensive Visual Inspection: Examine the main components of the suspension for signs of wear or damage, such as cracked springs, deteriorated bushings, or abnormal movement in the connections. Ensure that all bolts and nuts are securely tightened.

What to Check in a Suspension System:

• Air Suspensions: Check for oil leaks in the shock absorbers, damage to the springs, ensure the tires are correctly inflated, and verify proper tire alignment and balance. Inspect for worn kingpins.

• Mechanical Suspensions: Inspect U-bolts for looseness, cracks in spring hangers, and wear in the control arm bushings. Ensure that no springs are loose or cracked.

Regulations and Preventive Maintenance

According to FMCSA regulations, truck drivers must perform daily safety inspections before each trip, with special attention to suspension components. In California, the DMV recommends keeping a detailed record of each inspection to demonstrate compliance in the event of a roadside check.

Maintaining the unit´s suspension in good condition is essential for the safety of the driver and everyone on the road. Regular inspections not only prevent costly mechanical issues but also ensure compliance with state and federal laws.

Don´t let a minor oversight put your life and the lives of others at risk! Have a safe journey.
