Car idler arms are an essential component of a vehicle's steering system. They are responsible for maintaining the alignment of the steering linkage and providing a smooth and stable ride. Idler arms are typically located on the passenger side of the vehicle and are attached to the center link, which connects the steering gear to the front wheels. Without a functioning idler arm, the steering system may become loose and unresponsive, leading to unsafe driving conditions. It is important to regularly inspect and replace worn or damaged idler arms to ensure the safety and performance of a vehicle.
