Every component of suspension is a crucial element from the security point of view. Springs are among the most important elements, absorbing impacts caused by potholes and soil irregularities, besides guaranteeing the distance from the ground and the stability of the vehicle when swaying and braking.
To guarantee safety when driving, it is recommended to make a visual inspection of the springs and the whole suspension group condition each 10.000 km/6.200 miles, and replace the springs in the following cases:
1. When replacing your shock absorbers.
- > To obtain maximum performance.
- > Springs absorb impacts and guarantee the shock absorbers route (distance from the vehicle to the ground), in order to extend their durability.
- > We recommend replacing your shocks every 120.000 km/80.000 miles.
2. When the paint on the spring flakes off.
- > Signal of rust.
- > Rust destroys the treatment of the spring steel, favoring the appearance of micro-fissures that weakens the spring and causes its breakage or collapse.
3. When the vehicle is low
- > The front or the rear part of the vehicle is lower in relation to the ground, or there is a lateral drop.
- > Alteration in the suspension route (shock absorber and bump stop).
- > Irregular wearing of the tires.
- > Premature wearing of the shock absorbers, bump stop and bearings.
- > Alignment is impossible (negative bend).
4. When the spring coils are damaged
- > It happens when the spring loses part of its endurance and loses its shape in a way that its spirals crash.
- > Loss in the stability of the vehicle.
- > Heavy strokes in suspension.
- > Premature wearing of the tires, shock absorbers, bump stops, bushing and other suspension elements.
5. When bump stops are damaged
- > Springs are low or lose capacity for absorbing impacts.
- > Heavy strokes in suspension.
- > Premature wearing of the tires and elements of the suspension.
- > Cracks in the structure of the vehicle.
6. When the spring breaks
- > Breakage of one of the spring coils, causing an immediate drop in the vehicle height.
- > High possibility of losing control of the vehicle and imminent accident hazard.
To avoid problems caused by wrong spring application, which alters the characteristics of the vehicle and affects durability, always verify the following points before making the installation:
- > Year, make and model
- > Automatic transmission
- > Engine
- > Sport versions
- > 2 or 4 doors
- > Natural gas vehicles
- > Hydraulic direction
- > Springs are assembled by pressure in the suspension system and must be installed by qualified professionals that have the necessary knowledge and tools to guarantee a safe collocation and right assembly.
- > Do not cut the coils or heat the springs to try to lower the vehicle. This procedure voids the warranty and represents high risk of accident, as springs may break or come loose from the suspension support.
- > The ideal would be to replace the four spare parts, or at least do it by pairs (front or rear).
- > The balance and stability of the vehicle when bending or braking depend on the proper functioning of the whole spring/shock absorber group.
- > Up to date there is no technical remanufacturing process or repairing of helicoidal springs checked.
