Steering Rack: Purpose, Maintenance, and Replacement for the 2017 Subaru Impreza

The 2017 Subaru Impreza is equipped with a steering rack, making it a vital component of the vehicle's steering system. Contrary to some suspicions that it might not have one, the steering rack plays a crucial role in translating the driver's input from the steering wheel into the actual turning of the wheels. This setup is common in modern passenger cars, including the Impreza, due to its precision and relatively compact design.

So what exactly is a steering rack? The steering rack is part of a rack-and-pinion system, which forms the heart of most modern steering mechanisms. It consists of a flat, toothed bar called the rack that meshes directly with a round gear called the pinion attached to the steering column. When the driver turns the steering wheel, the pinion turns, moving the rack from side to side. This side-to-side motion is then transferred to the tie rods connected to the wheels, causing the vehicle to turn. The design is prized for delivering responsive and direct steering feedback, making it easier for drivers to feel connected to the road.

On the 2017 Subaru Impreza, the steering rack is typically paired with an electric power steering assistance system. This means rather than using traditional hydraulic pressure, electric motors assist the steering effort, helping to improve fuel efficiency and providing variable assistance depending on driving conditions. It also simplifies things under the bonnet, requiring fewer fluids and hoses compared to hydraulic setups.

Because the steering rack is so important to vehicle control and safety, it is one of the key components to keep an eye on during regular servicing. Over time, normal wear and tear can cause the bushings and seals inside the rack to degrade. This can result in unsuitable play or looseness in the steering wheel, unusual noises during turns, or even leaking fluid in older, hydraulic-assisted setups. While the 2017 Subaru Impreza's electric system eliminates hydraulic fluid concerns, wear in mechanical joints and seals can still cause performance issues.

When it comes to servicing the steering rack, technicians usually begin by conducting a thorough inspection of the steering system during routine maintenance or when steering issues are reported. This involves checking for excessive free play in the steering wheel, inspecting the tie rods and boots for damage or wear, and listening for unusual sounds like clunks or grinding when turning. If any problems are detected, they can indicate the steering rack or its components might be worn and in need of repair or replacement.

Another important aspect during service is ensuring the steering rack and related components are correctly lubricated. Although the 2017 Impreza's rack is part of a sealed system, the steering column and related linkages should still be checked for smooth operation and greased as necessary. Drivers should also keep an eye out for changes in steering feel or noise, as these could be signs that the rack is deteriorating.

When the steering rack reaches the end of its service life or has sustained damage, replacement becomes necessary. Replacing the steering rack on a 2017 Subaru Impreza is a task best left to a professional mechanic, as it requires specialized knowledge and tools to maintain wheel alignment and proper steering geometry. The process involves removing components like tie rods and power steering connectors, taking out the old rack, and fitting a new one in its place. Post-installation, a wheel alignment is essential to ensure the Impreza handles correctly and safety is maintained.

Steering rack replacement or maintenance is not just about improving steering feel but also a critical safety measure. If the steering rack fails or is significantly worn, it can lead to unpredictable handling and increase the risk of accidents. Thankfully, with timely service and attention to the signs mentioned above, drivers can prolong the life of their steering rack and enjoy smooth, responsive steering throughout their vehicle's lifespan.

For those who own a 2017 Subaru Impreza, keeping the steering rack in good condition means more enjoyable driving with responsive control, plus peace of mind knowing the vehicle is safe and roadworthy. Regular servicing checks, prompt attention to any steering issues, and choosing quality parts and service can make steering rack concerns a thing of the past for this popular Aussie hatch or sedan.
