SACHS recommendation:
Replacing defective suspension springs.

Defective springs negatively affect vehicle handling and road-traffic safety: They extend the stopping distance because they can no longer correctly absorb the forces which occur upon deceleration. In addition to that, tires lose road contact more easily and wear more quickly. In fast or tight corners, the vehicle has a greater tendency to move sideways and will break away earlier. If the vehicle accelerates or brakes, the body is subject to substantial movement. Furthermore, the ground clearance is reduced, which in turn, increases the tendency to "bottom out". Not least, damaged springs reduce the service life of shocks and dampers.

As only fully functional suspension springs can work perfectly with the other chassis components, experts at ZF Services recommend regular inspection at an automotive specialist workshop: If the spring shows corrosion damage, cracks or fractures, then workshop customers should have them replaced. When doing so, the guiding principle applies that the springs should always be replaced in pairs per axle. This significantly increases driving safety and also comfort and effectively protects the shocks and dampers, suspension strut mounts and tires from premature wear.
