Parts for your 2018 Subaru Impreza-Rack boots

Understanding Rack Boots on the 2018 Subaru Impreza

The 2018 Subaru Impreza is known for its reliable and responsive steering system that helps drivers navigate Australian roads with confidence. A key component often discussed in steering systems is the rack boots. But are rack boots relevant or even used on the 2018 Subaru Impreza? After checking technical references and Subaru's own service manuals, the answer is yes, the 2018 Impreza does use rack boots as an essential part of its steering rack assembly.

Rack boots, also sometimes called bellows or gaiters, are protective rubber covers that shield the inner tie rod ends and the steering rack itself from dirt, dust, moisture, and other contaminants. On the 2018 Subaru Impreza, these rack boots serve the same vital function, ensuring the longevity and proper operation of the steering rack components.

Since the rack boots play a critical role in protecting the steering mechanism, it's important for Impreza owners to understand their purpose and maintenance needs to keep the ride safe and smooth.

The steering rack on a Subaru Impreza is exposed to all sorts of environmental elements, from dirt and grime on unsealed country roads to the dust and grit found in urban settings. Without the rack boots, these contaminants could enter the steering rack assembly, causing excessive wear on the rack and pinion gears and the inner tie rods. This contamination would lead to premature failure of steering components, which in turn affects both safety and driving comfort.

Besides protecting against dirt and moisture, rack boots also help to retain the lubricant inside the steering rack. This grease ensures smooth movement and reduces friction between the moving parts. If a rack boot is torn or damaged, lubricant can leak out, and contamination can get in. Over time, this degrades the steering's performance and can result in costly repairs.

When it comes to the maintenance of rack boots on the 2018 Subaru Impreza, regular inspections are key. It is usually recommended to check the condition of the rack boots during routine servicing or every 20,000 to 30,000 kilometres, whichever comes first. That's especially true if the vehicle is driven on rough roads or off-road conditions more often than typical city use.

If a visual inspection reveals cracks, tears, or excessive wear on the rack boots, replacing them as soon as possible is crucial. Continuing to drive on damaged rack boots means exposing the steering rack to potential damage, which is a far more expensive fix than changing a boot. When replacing a rack boot, the mechanic will typically also inspect the inner tie rods for wear and check that the steering rack is still in good condition.

Another maintenance tip for Subaru Impreza owners is to avoid ignoring any signs of steering problems, such as unusual noises when turning the wheel or a vague or loose feeling in the steering. While these symptoms might relate to various issues, worn or damaged rack boots can be one possible cause since contaminants get past the seals and damage internal parts.

Replacing rack boots on the 2018 Impreza is not a complicated task for a professional mechanic but does require removing the inner tie rods and carefully fitting the new boots without damaging them. It is also important to use genuine or high-quality aftermarket rack boots designed specifically for the Impreza to ensure the right fit and durability.

Keeping rack boots in good order is a simple yet highly effective way to extend the life of the steering system on the 2018 Subaru Impreza. For drivers who like to do their own maintenance, investing a bit of time to check these rubber bellows for damage can save money down the track. And for anyone servicing their car at a workshop, a quick reminder to your mechanic to check the rack boots during a service is a smart move.

In short, rack boots protect your steering rack by keeping out dirt and moisture while holding the lubricating grease in place. Maintaining them through regular checks and timely replacements will help keep the 2018 Subaru Impreza steering smooth, safe, and reliable for every trip around town or out on the highway.
