Parts for your 2008 Subaru Exiga-Steering rack

2008 Subaru Exiga Steering Rack: what it does and how to look after it

Yes, the 2008 Subaru Exiga absolutely uses a steering rack. Technical sources including the Subaru Exiga (YA) Service Manual—Steering section, the Subaru FAST electronic parts catalogue, and 2008 market brochures list a rack-and-pinion steering gear with hydraulic power assist for the Exiga. That confirms a steering rack is both fitted and directly relevant to this model.

On this Exiga, the steering rack turns the driver’s input at the wheel into precise side-to-side movement at the front wheels, using a rack-and-pinion gear and a hydraulic pump for power assist. It gives the car tidy on-road feel, keeps effort light at parking speeds, and helps the Exiga track straight at motorway pace. When it’s in good nick, steering feels consistent and predictable, when it’s tired, the car can feel vague, heavy, or noisy.

Good servicing practice focuses on keeping the hydraulic system clean and the rack protected. Subaru specifies power steering fluid (ATF-type) for the hydraulic system, using the correct Subaru-approved ATF and keeping it fresh helps the internal seals live a long life. The rack boots (gaiters) protect the inner tie rods and rack bar from grit and moisture—cracked or greasy boots are a sign it’s time for attention. Tie rod ends also wear, which shows up as play or uneven tyre wear.

• Inspect rack boots, lines and banjo unions at each service for leaks, weeping, or cracks.
• Listen for whine from the pump and feel for notchiness through the wheel—both warrant a fluid check and further diagnosis.
• If fluid is dark or contaminated, have it flushed with the correct Subaru-spec ATF, many workshops in AU/NZ do this around 60,000–100,000 km or when symptoms appear.
• Replace worn inner/outer tie rods promptly and follow up with a four-wheel alignment.
• If the rack is leaking at the input shaft or end seals, a quality reconditioned or new rack is the go-to fix. Renew the rack mounts and crush washers on refit, and bleed the system per the workshop manual.

There’s no fixed replacement interval for the rack itself—condition rules. A trusted mechanic can check for free play with the wheels off the ground, confirm torque settings against the manual, and keep the Exiga’s steering feeling spot-on for Aussie and Kiwi roads.

Does the 2008 Exiga have electric or hydraulic steering?

The 2008 Exiga (YA series) uses a hydraulic power-assisted rack-and-pinion setup with an engine-driven pump. That’s what Subaru’s service documentation and parts listings show for launch-year models. It delivers natural road feel and light effort, provided the fluid and seals are healthy.

What are common signs the Exiga’s steering rack needs work?

Look for power steering fluid spots under the front crossmember, a heavy or notchy feel at low speed, play around centre, clunks over bumps, or uneven tyre wear. Any split rack boots or wetness around the rack ends or input shaft deserve quick attention to prevent internal wear.

What fluid should be used, and when should it be changed?

Use Subaru-approved ATF for the power steering system (often referred to as Subaru ATF-HP or equivalent, per the owner’s manual). Many workshops in Australia and New Zealand will flush or replace the fluid between 60,000 and 100,000 km, or sooner if it’s dark, foamy, or if noise appears. Always confirm the exact spec in the vehicle’s handbook.
