Understanding Control Arms on the 2018 Subaru Exiga: Purpose, Maintenance, and Replacement Tips

The 2018 Subaru Exiga does indeed come equipped with control arms as part of its suspension system. Control arms are a crucial component that plays a significant role in ensuring the vehicle's handling, ride quality, and overall driving safety. For those who own or service a 2018 Subaru Exiga, understanding what control arms do and how to maintain them can help extend the life of the suspension and keep the vehicle driving smoothly.

Control arms are a key link between the wheel hub and the car's chassis. They allow the wheel to move up and down while keeping it properly aligned with the body of the car, allowing for better handling and comfort as the vehicle drives over bumps or uneven surfaces. Essentially, each control arm connects the wheel assembly to the frame and provides the necessary pivot points for the wheels to travel up and down independently.

On the 2018 Subaru Exiga, control arms work alongside other suspension parts such as bushings, ball joints, struts, and shocks. Typically, the Exiga uses both upper and lower control arms at the front suspension, while the rear suspension design may vary but generally still includes control arm components to ensure the rear wheels maintain their proper alignment. Subaru's use of control arms is a fairly traditional approach, consistent with many other passenger vehicles where precise wheel alignment and suspension articulation are essential for both performance and comfort.

The purpose of control arms extends beyond just connecting points. Because the wheels need to absorb shock from the road and keep stable contact with the ground, control arms provide the flexibility needed for vertical movement while restricting unwanted lateral motion. They also keep the wheels aligned concerning the road and the driver's steering inputs. This helps prevent tyre wear and contributes to a safer, more controlled ride. The bushings and ball joints fitted to control arms aid in isolating road noise and vibrations, ensuring the ride is as smooth as possible.

When it comes to maintenance, control arms on the 2018 Subaru Exiga don't typically require regular replacement but do need to be checked periodically. Like any suspension component, they are subject to wear and tear - especially the bushings and ball joints which allow for smooth movement. Over time, these parts can degrade due to road conditions, exposure to dirt, water, and salt, or simply from mileage. Worn bushings might cause clunking noises, loose handling, or uneven tyre wear, whereas faulty ball joints could make your steering feel unstable or cause alignment issues.

Servicing control arms as part of regular maintenance usually involves inspection rather than outright replacement. Mechanics will look for signs such as:

• Cracks or tears in the rubber bushings
• Excessive play or looseness in the ball joints
• Any bending or physical damage to the control arm itself
• Unusual noises or vibrations experienced when driving

If any of these symptoms are present, it is advisable to have the control arms serviced right away. Addressing worn control arms early helps avoid further suspension damage or unsafe driving conditions. When replacement is necessary, it's important to use Subaru-approved or high-quality aftermarket parts to maintain the original handling characteristics of the Exiga.

Replacing control arms on the 2018 Subaru Exiga is not a complicated task for a qualified mechanic, but it should always be followed by proper wheel alignment. Since control arms directly affect the geometry of the suspension, incorrect installation or failure to do a wheel alignment after replacement can lead to uneven tyre wear and poor handling, negating the benefits of the new control arms.

Keeping control arms in good condition not only preserves ride comfort but also supports the overall safety of the 2018 Subaru Exiga. Drivers who frequently take roads with potholes or rough terrain should pay close attention to suspension health, including control arm integrity. Likewise, if the vehicle feels unstable or noisy during turns or over bumps, getting the suspension checked promptly ensures no further damage occurs.

Ultimately, control arms are a vital piece of the suspension puzzle on the 2018 Subaru Exiga. They provide flexibility, stability, and control that directly impact how the car drives and responds to the road. Regular inspections and timely replacements when needed are the best ways to keep these components performing at their best, preserving the smooth, safe drive that Subaru owners value.
