Understanding Control Arms on the 2018 Subaru XV

The 2018 Subaru XV is a popular compact crossover SUV known for its reliability, all-wheel drive capability, and smooth ride. When it comes to the suspension system, control arms are indeed a key component fitted to this vehicle. For anyone interested in the ins and outs of their Subaru XV's suspension, understanding control arms, their purpose, and their maintenance is worthwhile.

Control arms, sometimes called A-arms or wishbones, are essential parts of the front and rear suspension. On the 2018 Subaru XV, control arms connect the wheel hub and steering knuckle to the vehicle's frame or body. This linkage plays a crucial role in allowing the wheels to move up and down while maintaining proper wheel alignment and stability during driving.

Control arms work together with other suspension components such as ball joints, bushings, shocks, and struts. Their primary purpose is to enable the suspension to absorb bumps and road imperfections while keeping the wheels firmly planted on the road surface. Without control arms, the wheels could move erratically or out of alignment, which would affect vehicle handling, ride quality, and safety.

The control arms on the Subaru XV commonly include a lower control arm in the front suspension, and in some cases, upper control arms depending on the design of the suspension system. These control arms have rubber or polyurethane bushings that cushion the connection points, reducing noise and vibration felt inside the cabin.

Over time, control arms and their bushings can wear out due to constant stress, road conditions, and exposure to the elements. Worn or damaged control arms can lead to symptoms such as:

• Uneven or premature tyre wear
• Unstable or wandering steering
• Clunking sounds when driving over bumps
• Reduced handling performance
• Visible damage or corrosion on the control arm itself

Replacing or maintaining control arms on the 2018 Subaru XV is an important service to keep the ride comfortable and safe. While some controls arms might last a long time, it's good practice to have them inspected during regular servicing intervals, especially if the vehicle is driven frequently on rough roads or off-road.

When servicing the control arms, mechanics typically look at the condition of the bushings and ball joints for any signs of cracking, separation, or excessive play. If bushings are worn out, they might be replaced independently or as part of a whole control arm assembly, depending on the damage and labour costs. In some cases, if the control arm shows bending or rust damage, the entire arm should be replaced.

It's worth noting that aftermarket control arms and OEM (Original Equipment Manufacturer) parts are available for the Subaru XV. While OEM parts are generally recommended for the best fit and longevity, quality aftermarket parts can offer reliable alternatives and sometimes better pricing.

Installation of control arms usually involves removing the wheel, disconnecting the ball joint and bushing mounting points, and then fitting the new component before realigning the suspension. After replacement, a wheel alignment is crucial to ensure the Subaru XV drives straight and handles properly.

DIY enthusiasts can attempt control arm replacement if they have the right tools and mechanical know-how, but given the critical role these parts play in safety and handling, professional servicing is often the safer option. Additionally, a professional will inspect related suspension components to ensure nothing else is contributing to handling issues.

If one hears any knocking noises, feels excessive vibration, or notices changes in steering response, it's a wise move to get the control arms checked sooner rather than later. Neglecting worn control arms can lead to bigger suspension problems and even impact braking performance.

Taking good care of the suspension on a 2018 Subaru XV keeps the vehicle delivering its trademark confident and smooth drive, whether cruising city roads or tackling weekend adventures. Servicing control arms is one of those smaller maintenance jobs that pay big dividends when it comes to comfort and safety on the road.
