Parts for your 2017 Subaru Exiga-Power steering hose

2017 Subaru Exiga power‑steering hose: what it does and how to look after it

Technical sources including Subaru’s Factory Service Manual for the Exiga/Crossover 7 (YA/YAM series, 2015–2018) and the Subaru FAST electronic parts catalogue show the 2017 Subaru Exiga runs a conventional hydraulic power‑assisted steering system with both a high‑pressure hose (pump to rack) and a low‑pressure return hose (rack to reservoir). That means a power‑steering hose is absolutely relevant on this model.

On the 2017 Exiga, the power‑steering hoses carry specially formulated ATF‑type fluid between the belt‑driven pump, steering rack and reservoir. The high‑pressure line handles pump output at significant pressure, while the return hose brings fluid back to the reservoir. Together, they let the rack get the hydraulic assist needed to keep steering light and predictable at parking speeds while staying stable on the open road.

As part of routine servicing, a quick check of the hoses is smart. Look for sweating around crimps, perishing or cracks in the rubber, damp spots near banjo fittings, and any chafe where the hose passes brackets. If there’s a faint whine on cold starts, aeration from a loose clamp or a tired pump inlet seal can show up in the reservoir as foamy or discoloured fluid—worth inspecting before it becomes a leak.

• Fluid: Use Subaru‑approved power‑steering fluid/ATF meeting the spec in the owner’s manual (commonly Dexron III‑type). Avoid mixing fluid types.
• Intervals: While Subaru doesn’t always specify a strict flush interval, many workshops in Australia and New Zealand refresh fluid every 60,000–100,000 km, or sooner if it’s dark or smells burnt.
• Heat and routing: The Exiga’s high‑pressure hose lives near engine heat, make sure any factory heat shields and clips are present so the hose doesn’t soften or rub.
• Replacement signs: Persistent weeping at crimps, swelling, soft spots, cracks, or steering heaviness and noise are cues to replace the hose.

When replacing a hose, use quality OEM‑grade parts, new sealing washers, and correct torque on banjo bolts. After fitting, bleed the system by turning the wheel lock‑to‑lock with the front wheels raised, topping up fluid as bubbles purge. A short road test and recheck for seepage under the bonnet finishes the job nicely.

Popular questions about 2017 Subaru Exiga power‑steering hoses

How can someone tell if the high‑pressure hose is failing on a 2017 Exiga?
Common giveaways include oily residue around the crimped sections, drops of fluid under the front right of the car after parking, or a steering whine that gets louder as fluid level falls. If the reservoir level keeps dropping or the fluid looks aerated, it’s time for a closer inspection.

What fluid should be used after a hose replacement?
Use a Subaru‑approved power‑steering fluid/ATF that meets the specification in the Exiga owner’s manual—typically a Dexron III‑type ATF. Don’t mix mineral and synthetic fluids unless the product clearly states compatibility, and always bleed the system thoroughly.

Is hose replacement a DIY job or workshop only?
Skilled DIYers can handle it with proper tools, but the high‑pressure line involves tight access, banjo fittings, sealing washers and precise torques. Many owners prefer a workshop to ensure correct routing, secure crimp connections and a clean bleed.
