How Often Should Car Control Arms Be Replaced?
2 Answers
Car control arms generally do not need replacement unless there is impact deformation, cracks, or other special circumstances that necessitate replacement. Additionally, deformation, bushing aging, or noticeable jerking while driving should also prompt consideration for replacement. Introduction to Car Control Arms: They are part of the car's suspension system, and their main functions are: transmitting forces and torque between the wheels and the frame, buffering the impact from uneven road surfaces transmitted to the frame and body, dampening the resulting vibrations, and ensuring smooth driving. Symptoms of faulty control arms include: Clicking noises from the faulty side when driving on uneven roads; inconsistent steering feel, varying between light and heavy, making it difficult to control; severe cases may cause braking deviation; reduced vehicle shock absorption, lowering ride comfort; decreased vehicle stability; and reduced flexibility when turning.
Having driven for many years, I've found that the replacement time for control arms varies from person to person. For someone like me who commutes in the city with a sedan, it's usually checked every 100,000 kilometers or when the car is over 8 years old. Driving habits are crucial: if you often drive fast or make sharp turns, the wear is faster. Once I ignored this issue, and my car made a creaking sound when turning, even pulling to one side—it turned out the control arm rubber was cracked. After replacing the part, the handling became much more stable, preventing more serious tire damage. I recommend having the suspension tested during regular maintenance, especially for those who often drive on bumpy roads. Safety is no small matter, and timely maintenance can save big money. Generally, a thorough inspection every 5 years is a safe bet.
