What are the signs of a faulty control arm?
In case of control arm failure, the vehicle may pull to one side. The wheels become misaligned. The tyres wear unevenly. The shock-absorbing properties of the suspension are impaired, which is especially noticeable when driving on poor quality roads. While driving, you can hear distinctive sounds: knocking, squeaking, or clicking. Oversteer or understeer can occur and there may be steering delay.
Is it dangerous to drive with a bad control arm?
A faulty arm causes poor handling, which negatively affects road safety. There is a high risk of skidding on slippery surfaces. A broken control arm poses a risk of excessive tilt of the wheel, which is very dangerous when driving at high speed, because you could lose control of the car completely.
Can I only replace one control arm?
You could change only the damaged control arm, but it’s recommended to replace these parts in pairs especially if they have been used for a long time. Even a control arm used for a short time may have different technical characteristics from those of the new component. In addition, the parts have approximately the same lifespan. Therefore, the failure of one usually means the other will break down soon.
