Parts for your 1998 Subaru Forester-Power steering hose

1998 Subaru Forester power‑steering hose — what it does and how to look after it

Technical references confirm the 1998 Subaru Forester (SF) runs a conventional hydraulic power steering setup with dedicated hoses. The Subaru Factory Service Manual for the 1998 Forester, Steering System—Power Steering, details a vane pump, reservoir and steering gear connected by a high‑pressure hose (pump to rack) and a low‑pressure return hose (rack to reservoir). Subaru’s FAST electronic parts catalogue for MY1998 Forester lists both a “pressure hose assembly” and a “return hose,” and major aftermarket catalogues such as Gates and Edelmann publish direct‑fit pressure lines for this model. That means a power‑steering hose is absolutely relevant and fitted to this vehicle.

The power‑steering hoses on a 1998 Forester do the heavy lifting in the hydraulic circuit. The pressure hose carries ATF from the pump to the rack under significant pressure, while the return hose feeds fluid back to the reservoir at low pressure. Together they let the steering feel light at the wheel, damp pulses from the pump and cope with engine movement without kinking or leaking. Subaru specifies automatic transmission fluid (Dexron II/III) for this system, so it’s not the place for generic “power steering” fluids.

For servicing, regular checks go a long way. At each service interval, have the hoses inspected for sweating, cracking, bulges, soft spots, frayed heat shields, rusted crimps and any wetness around banjo fittings. Also watch the fluid level and colour — frequent top‑ups or dark, burnt‑smelling fluid hint at hose or seal troubles.

• When replacing the pressure hose, always fit new crush washers at banjo joints, secure all brackets and heat shields, and route the line exactly as per the original to keep it clear of the exhaust.
• For the return hose, use hose specifically rated for power‑steering/ATF, not generic coolant or fuel hose, and use quality clamps.

Bleeding after hose work is straightforward:

1. Front wheels off the ground, engine off, fill the reservoir with Dexron III and slowly turn the wheel lock‑to‑lock several times to purge air.
2. Top up, start the engine and continue gentle lock‑to‑lock turns while watching for bubbles. Keep topping up until the fluid stays clear and quiet.
3. Lower the car, road test, then recheck for leaks and final level.

Don’t run the pump dry, don’t overtighten fittings, and dispose of old ATF responsibly. On an SF‑series Forester that’s now well into classic territory, proactive hose replacement is cheap insurance against sudden fluid loss, heavy steering and a howling pump.

Popular questions about 1998 Subaru Forester power‑steering hoses

Does a 1998 Forester actually have power‑steering hoses?
Yes. The factory service manual and Subaru’s FAST parts catalogue for the 1998 Forester show a high‑pressure pump‑to‑rack hose and a low‑pressure return hose. Aftermarket catalogues also list direct‑fit hoses, so replacement parts are readily available.

What fluid should go in the power steering on this model?
Subaru specifies ATF meeting Dexron II/III for this era. Using standard “power steering fluid” can cause seal issues or noise. The reservoir cap and owner’s handbook back up the Dexron recommendation for the 1998 Forester.

How can air be bled after fitting a new hose?
Fill the reservoir with the correct ATF, raise the front wheels, and with the engine off turn the wheel slowly from lock to lock several times. Top up, start the engine and repeat gentle lock‑to‑lock turns until bubbles stop and the pump quietens. Recheck level after a short drive.
