Control Arms 

The design of a control arm in a car is quite simple. It is a rigid component that moves rotationally around a fixed axis. Each cycle ends with a return to the starting position, and this return can either be active or idle. 

The type of control arm factory-fitted to a vehicle directly influences the way it functions and its overall performance. Nowadays, you can find models with transverse and oblique control arms, or both transverse and longitudinal. These configurations help designers eliminate wheel camber and variation in the track width. 

At Inter Cars, we offer only carefully selected, high-quality control arms from the best brands. Both aftermarket and OEM parts form a comprehensive product range. See for yourself! 

What is the function of control arms in a car? 

The design of the control arm is straightforward, yet it serves an important role. Without a properly functioning control arm made from durable materials, a vehicle wouldn’t operate correctly. The control arm plays a crucial role in the vehicle's suspension system, connecting the wheels to the car’s body. As a result, control arms help maintain the proper steering alignment, not only in a straight line but also during turns. Alongside the control arms, bushes are also vital, as they form the direct connection between the body and the suspension system. Made from a combination of metal and rubber, they help transfer vibrations. 

The control arms offered by Inter Cars are made from the highest quality metals and their alloys. This is crucial for their long-term durability, as they are subject to the stresses from road imperfections and damage. 

Regardless of the type of suspension or the materials used in its construction, control arms are typically made from a combination of steel, aluminium, and cast iron. They are also available as pressed profiles. The sheet metal used is of construction-grade quality, offering enhanced strength properties. 

What types of control arms are available? 

Control arms installed in cars can vary, and in many cases, sets containing two types of control arms are used. The classic model is a rigid transverse control arm. This type allows the vehicle to rotate simultaneously around both a parallel and a longitudinal axis. When installing such control arms, it is common to choose two arms forming either a trapezoidal or parallel arrangement – consisting of two identical arms or one longer arm. 

Longitudinal control arms, on the other hand, are responsible for rotation around an axis perpendicular to the vehicle’s symmetry plane. They are used for the steering wheels. Oblique control arms are typically installed at non-steering wheels. They rotate around both the longitudinal axis and the vehicle's transverse symmetry axis. 

How is a control arm installed? 

Control arms in cars require periodic replacement. Most drivers choose to take their car to a mechanic, but you may prefer to do it yourself. 

Transverse, oblique, and longitudinal control arms are located behind the wheel. To replace them, the car must be lifted, the wheels removed, and the control arm’s pin bolts unscrewed. A rubber mallet can help at this stage, especially if the pin is tightly seized. 

The next step is installing the new control arm. It is attached to the vehicle's body using metal-rubber bushes, and to the wheel hub using the control arm pin. After this, reattach the bolt and wheel. Remember, once the mounting is removed, it’s important to check the condition of the pins, as they may also need to be replaced. 

When should you replace a suspension control arm? 

The control arm is a crucial component for the proper functioning of the suspension. Therefore, when signs of wear or damage occur, it’s essential to replace it. Signs of deteriorating control arms include reduced response during steering, issues and jerking when starting, and difficulty maintaining a straight path. Sometimes, you may also hear knocking sounds when driving on rough roads. 

The control arms available in our shop are tailored to various car types. While some drivers previously attempted to refurbish control arms, today replacing them with new ones is a much better option. The products in our store include both OE/OEM parts and high-quality aftermarket replacements.

FAQ Section

What role do control arms play in a car?

Control arms connect the wheels to the car’s body, maintaining proper steering alignment during turns and ensuring vehicle stability.

What types of control arms are there?

Cars typically have transverse, oblique, or both transverse and longitudinal control arms. Some vehicles have single control arms, while others feature more advanced and expensive multi-link suspension systems.

When should you replace suspension control arms?

Control arms should be replaced when signs of wear or damage appear, such as poor steering response, issues when starting, difficulty maintaining a straight path, and knocking noises when driving on uneven surfaces. For replacement, it's best to choose high-quality brand-name replacements.
