Understanding Rack Boots on the 2017 Subaru Legacy

The 2017 Subaru Legacy features a modern rack and pinion steering system, which plays a key role in providing precise and responsive handling. A question that often pops up among owners and enthusiasts is whether this model uses rack boots, sometimes called steering rack gaiters, and what role these components play if they are fitted.

When it comes to the 2017 Subaru Legacy, technical and service manuals confirm that rack boots are indeed part of the steering system. These rubber or flexible gaiters cover the exposed ends of the steering rack, protecting the internal components. So, if you're keen on understanding what rack boots do, why they matter, and how to keep them in good nick, here's a detailed look tailored to the 2017 Legacy.

Rack boots serve as essential protective covers for the steering rack's moving parts, particularly the inner tie rods and the rack itself. The steering rack is responsible for converting the rotational movement of the steering wheel into the linear motion required to turn the wheels. This involves exposed components that require shielding from dirt, grime, water, and other contaminants that can cause premature wear or failure.

Without rack boots, the rack and pinion system would be directly exposed to the harsh conditions under the car. Road debris, dust, moisture, and grease could get into sensitive areas, causing corrosion and accelerating wear on the seals and internal components. Eventually, this could lead to leaks in the hydraulic power steering system (if fitted), or in electric power steering systems, degrade the rack's mechanical integrity.

For Subaru Legacy owners, keeping an eye on the rack boots is an important part of maintaining smooth steering operation and prolonging the lifespan of the steering rack itself. Fortunately, rack boots are generally straightforward components to inspect and replace if necessary.

Over time, the rubber on rack boots can dry out, crack, or even tear, especially if the vehicle spends a lot of time in harsh weather conditions or on rough roads. Common warning signs of a failing rack boot include grease leaking out from around the boot area or visible cracks and splits in the boot material itself. If these symptoms are ignored, it can allow dirt and debris to enter the steering system, which can lead to expensive repairs down the track.

Regular servicing and inspection of the steering rack and boots should be part of the vehicle's routine maintenance schedule. During a typical service check for the 2017 Subaru Legacy, mechanics will look for any damage or wear on the rack boots when the vehicle is lifted and the steering system is accessible.

Replacing rack boots on a 2017 Legacy is generally an affordable repair compared to major steering system overhauls. The process involves removing the clamps holding the boot in place, sliding off the old boot, inspecting the inner components for damage, and fitting a new boot along with fresh grease to ensure smooth operation. The new boots help keep the steering components protected against contaminants and help maintain proper lubrication.

Maintaining the rack boots also contributes to overall driving safety and comfort. A well-protected rack means smoother steering feel, fewer noises such as knocking or clunking when turning, and consistent steering response without any stickiness or binding. This is especially important for a car like the Subaru Legacy, which is known for its excellent handling and reliability.

In short, while rack boots might seem like small and simple components, they play an outsized role in protecting the steering rack from damage and wear. For owners of the 2017 Subaru Legacy, regularly checking these boots during servicing and replacing them when worn or damaged is a smart way to keep the steering system in top shape and avoid costly repairs.

As a bit of extra advice, if you do notice a damaged rack boot on your Legacy it is a good idea to have the steering rack and inner tie rods inspected at the same time. This ensures there has been no contamination or damage that could affect the handling or safety of your car.

Taking care of your rack boots is a simple but effective way to support the longevity of your Subaru Legacy's steering system. It's one of those little jobs that can keep your daily drive smooth, safe and trouble free for many kilometres to come.
