About truck suspension: why the truck spring is a crucial
The truck spring, whether leaf or air, is designed to support the load, absorb vibrations and ensure good weight distribution at the rear of the vehicle. An efficient spring suspension also extends the life of several other components: transmission, tires, brakes, etc.
Types of springs commonly used:
- Traditional leaf springs
- Air springs (air suspension)
- Combined systems with rubber and reinforced bolts
What are the signs of wear on a heavy vehicle spring?
Here are the main indicators that it is time to repair or replace a spring:
1. Truck leaning to one side
This is a classic sign of a weakened spring at the rear. This often affects Ford, Ram or Chevrolet trucks under heavy load.
2. Sagging of the trailer or rear of the truck
If ground clearance is reduced even without excessive load, your leaf springs are no longer doing their job. This can affect transport capacity and driving safety.
3. Abnormal noises (squeaking, rattling)
A worn spring produces vibrations and noise. This can damage other parts of the suspension system.
4. Unstable driving, excessive bouncing
If your Sicard, Freightliner or GMC truck becomes difficult to manoeuvre, your spring suspension may need to be checked.
What are the consequences of a worn spring on heavy vehicles?
A defective spring can lead to:
- Accelerated wear of tyres and shock absorbers
- Fatigue of the chassis
- Reduction in the performance of the braking system
- Increased risk of accident, especially under heavy load
This is why preventive maintenance is strongly recommended, particularly for fleets of commercial vehicles or logistics/freight vehicles.
