Steering problems: If you notice that your steering feels loose or unstable, it could be caused by worn or damaged lower control arm bushings or ball joints. Here is a list of signs that your lower control arm may need replacing:Ĭlunking noise when driving over bumps: If you hear a clunking noise coming from the suspension when driving over bumps or uneven terrain, it could be a sign that the lower control arm bushings or ball joints are worn. Ball joints tend to wear out faster than bushings and it is not uncommon for them to be the first component to fail in the control arm. They can wear out or become damaged over time, leading to the need for replacement. This means that if the bushings, ball joints or other components are worn or damaged, the enTyre lower control arm assembly may need to be replaced.īoth ball joints and bushings are parts of the lower control arm that experience a lot of movement and stress as the vehicle travels over bumps and dips in the road. Sometimes they only come as part of a lower control arm assembly. It's important to note that lower control arm bushings, ball joints and other components that connect the lower control arm to the vehicle, are not always sold individually. Signs That Your Lower Control Arm Needs Replacing It's important to note that lower control arm issues can often manifest as other problems like uneven Tyre wear, alignment issues, or steering problems, it's important to have the vehicle inspected by a qualified mechanic if you suspect any issues. If the vehicle is driven frequently on rough or uneven terrain, this can cause the lower control arm to fail prematurely. Overuse: Lower control arms are subjected to a lot of stress and strain as the vehicle travels over bumps and dips in the road. Impact damage: If the lower control arm is involved in an accident or collision, it can be damaged or bent, leading to failure. Wearing of bushings or ball joints: Over time, the bushings or ball joints that connect the lower control arm to the vehicle can wear out, causing the arm to loosen and lose its ability to control the motion of the wheel hub assembly.Ĭorrosion: If the lower control arm is exposed to salt, water, or other corrosive materials, it can rust and weaken, leading to failure. Lower control arms can fail for a variety of reasons, some of which include: Various parts of the assembly may wear out as well, such as the bushings or ball joints. Z:\Weekly Newsletters\2023 20 January They will wear out faster if you go over a large pothole or are involved in a car accident. These assemblies normally wear out between 150,000 and 200,000 Kilometres. Over time, the control arm assembly can become worn or bent. If lower control arm is worn or damaged, it can cause alignment issues, uneven Tyre wear, or steering problems. The lower control arm is typically a vital part of the suspension system, and it works in conjunction with other suspension components, such as the upper control arm, shocks, and struts, to provide a smooth and stable ride. The lower control arm also helps to control the caster angle, which is the angle of the steering axis. The bushings or ball joints also allow the wheel to move in and out, which is called camber. The lower control arm has bushings or ball joints that allow it to pivot or rotate, which allows the wheel to move up and down with the bumps and dips in the road. The lower control arm plays a critical role in the suspension system, as it helps to control the motion of the wheel hub assembly, and helps to keep the wheel in alignment with the rest of the vehicle. They are typically a long, tubular metal arm that connects the wheel hub assembly to the frame or chassis of the vehicle. Lower control arms are a component of a vehicle's suspension system.
