If you perform a proper maintenance on your truck’s suspension, then you can prevent accidents, ensure the stability of the vehicle while driving and avoid irregular wear of other parts, such as tires, among other problems. The suspension is a system composed by springs and shock absorbers that offers stability for the truck. Their functions are:
- Optimize stability while driving
- Support the load of the vehicle
- Reduce the blows and vibrations generated while driving
- Connect the suspension and wheels to the frame
- Efficiently transmit the braking and driving force
Several problems can arise when the suspension is in bad condition, such as causing the truck's steering to pull to the side where there is some kind of damage. This can lead to uneven and premature tire wear, as well as damaging the chassis, causing vibrations and blows to the vehicle body and parts. This will probably reduce the life of the suspension.
- Do not exceed maximum vehicle load.
- Avoid strong impacts on the tires.
- Distribute the load evenly, avoiding overweight at only one point of support.
- Do not load the truck the night before, because this generates a direct wear on the support points. When the vehicle is in motion this does not happen because the weight is evenly distributed throughout the trailer.
- For the best suspension performance, the recommendation is to keep all the components of the system correctly tight.
Regular suspension maintenance
Make sure that your trusted repair shop performs the following procedures:
- Visually inspect the suspension every 3 months.
- Tighten the parts at least once per year.
- Frequently check chassis lubrication.
- Regularly check the condition of the suspension rubber parts.
- When tightening a screw with a torque wrench, assure the gasket is rust free and clean.
- Replace old screws with new ones and make sure they are the same in size and torque value.
- Grease the elements and readjust the suspension every 5,000 km.
- Perform wheel alignment and balance every 10,000 km.
- Properly re-tighten the U-bolts, because once tightened, they will expand and you won’t be able to tighten them back correctly.
- Check suspension tension in every trailer before operating.
- Regularly inspect the bushings located on the torsion arms.
- Visually inspect shock absorbers for damages, fissures, etc. Check for oil leaks.
