The control arm is an important component, responsible for ensuring not only ride comfort but also occupant safety. Mounting kerbs at high speed, poor road surfaces, material fatigue and high forces to which control arms are subjected are all factors that can cause them to fail. Herth+Buss explains more.
Even just on starting and braking, the control arms are subjected to enormous tensile and compressive forces. In many cases, problems reported by customers such as increased steering wheel play, loud rolling noise, uneven tyre wear or a loss of ride comfort can be attributed to defective control arms or control arm bushes.
When a control arm’s final hour has passed and it’s completely worn out, the only helpful course of action is often to install a new one. Allowing a customer to continue to drive despite having a defective control arm can have expensive consequences and can pose a threat to safety – the erratic and delayed steering movements make the journey increasingly difficult and not only reduce the enjoyment of driving, but also the safety of the vehicle’s occupants. Furthermore, defects on control arms that aren’t repaired can cause damage to other suspension and steering components in the long term. Other parts of the axle, for instance, suffer as a result of the defective control arms, as the forces and movements then need to be compensated for by other components which are not designed for this function.
It is imperative to perform an axle alignment after replacing the control arms due to the fact that these have such a considerable influence on the car’s handling. Doing so ensures that they form one precisely balanced unit together with the struts. Axles that are not aligned or are incorrectly adjusted can lead to both a deterioration in handling and worn-out control arms.
The Jakoparts range from Herth+Buss includes an extensive selection of high quality chassis and steering components for a variety of Asian vehicles and platform share vehicles. The control arms that form part of this range are more than capable of performing their leading role in the event of repairs to the suspension. Due to the certified manufacturing process, these are precisely tuned to each other and form a high-quality and durable unit. According to Herth+Buss, an optimum fit is assured and therefore the ultimate in safety and driving comfort is guaranteed. This guarantees a stable road position even in critical situations.
