Rack Boots on the 2009 Subaru Impreza: What You Need to Know

The 2009 Subaru Impreza, a popular choice among Aussie drivers, uses a rack and pinion steering system, which is standard for many vehicles of this type and era. One key component often discussed with rack and pinion setups is the rack boot. But does the 2009 Subaru Impreza actually use rack boots, or are they something you can safely overlook during maintenance?

After reviewing multiple technical sources and workshop manuals for the 2009 Subaru Impreza, it turns out that this vehicle does indeed use rack boots. These are sometimes called bellows or gaiters and are located at each end of the steering rack's inner tie rods. Their job might seem small, but they play a crucial role in keeping the steering assembly protected and working smoothly.

Rack boots are flexible rubber covers that shield the exposed ends of the steering rack from dust, dirt, moisture, and road grime. Without these boots, contaminants can get inside the rack and pinion mechanism, which can cause premature wear and even failure of components.

Why are rack boots important? Think of them as the first line of defence for the steering rack's internal components. The steering rack slides back and forth as the driver turns the wheel, allowing the wheels to pivot left and right. If dirt and moisture get into this sliding mechanism because the boots are cracked or missing, it can lead to corrosion or damage to the rack's internal surfaces. This can cause issues like stiff steering, excessive play, or even a total steering failure in extreme cases.

Given how crucial rack boots are to protecting the steering rack, it's not surprising that they are a standard part fitted to the 2009 Subaru Impreza's steering system. Most Subaru workshop manuals and parts catalogs will list rack boots as a replacement item, which means they are designed to wear out over time and need to be inspected, maintained, or replaced as part of regular servicing.

Now that it is clear rack boots are fitted to the Impreza, here's what drivers and mechanics should know about maintaining or replacing these little but important parts.

When servicing a 2009 Subaru Impreza, it's wise to include rack boot inspection as part of your steering and suspension checks. Over time, these rubber boots can develop cracks, tears, or holes due to exposure to harsh elements, prolonged UV light, or general wear and tear from steering movement. Any damage can compromise their ability to keep dirt and water out.

Here are some key points on rack boot maintenance and replacement:

• Regular Inspections: During routine services such as tyre rotations, wheel alignments, or suspension checks, make a point to visually inspect the rack boots. Look for splits, tears, grease leakage, or signs that the boots are loose or have slipped off the rack.
• Grease Leakage: Sometimes torn boots can let the grease inside the rack slip out, reducing lubrication where it is needed most. If you spot dirty grease on or around the boots, it's time to replace them to keep the steering rack properly lubricated.
• Driving Conditions Matter: If the car is often driven on gravel roads, through wet or muddy conditions, or in areas with a lot of dust, then the boots will face tougher conditions and may wear out more quickly.
• Replacement Procedure: Replacing rack boots is typically a job for a mechanic or someone with decent DIY skills and the right tools. It involves removing the tie rods, sliding off the old boots, cleaning and lubricating the rack, then fitting new boots with clamps or clips to ensure a tight seal.
• Use Genuine or Quality Parts: Genuine Subaru rack boots or high-quality aftermarket alternatives should be used to ensure durability and proper fitment. Cheap inferior boots might crack or tear sooner and leave your steering rack vulnerable.

Because the steering rack is so critical to safe vehicle handling, having the rack boots in good shape helps protect your investment and keeps the steering feeling tight and responsive. Ignoring damaged boots can lead to costly repairs down the line, as contaminated steering racks might need full replacement or expensive rebuilds.

All up, rack boots might not be the most glamorous part of a 2009 Subaru Impreza, but they are essential defenders of your steering system's health. Taking a few minutes to check them during regular servicing can save a lot of headaches and keep your car steering true on Aussie roads for years to come.
