Parts for your 2017 Nissan Navara-Power steering hose

2017 Nissan Navara Power Steering Hose — purpose, care, and when to replace

Relevant and used: On the 2017 Nissan Navara (D23/NP300), a power steering hose is absolutely part of the vehicle. Technical documentation including the Nissan Navara D23 Electronic Service Manual (Steering System, ST section) details a belt-driven hydraulic power steering pump feeding the rack via a high-pressure hose, with a return hose to the reservoir. Nissan’s parts catalogues (FAST/Global Parts Catalogue) also list the high-pressure hose (pump to gear) and the return hose (gear to reservoir) for D23 models in this year range. That confirms the Navara uses hydraulic power assistance with dedicated hoses rather than full electric power steering.

What it does: The power steering hose carries hydraulic fluid under pressure from the pump to the steering rack, then returns it to the reservoir. Under load—think towing, corrugations, or tight parking—the high-pressure hose handles serious pressure while keeping steering light and predictable. If it weeps or bursts, steering can go heavy quickly and the pump can be damaged from running low on fluid.

Servicing tips for a 2017 Navara’s power steering hose:

• Inspect regularly for dampness, cracking, chafe marks, and loose clamps—especially around banjo fittings and where the hose passes near hot or moving components.
• If replacing the high-pressure hose, use new sealing washers, torque the banjo bolt to spec per the service manual, and keep all mating faces spotless.
• Bleed the system after any hose work: wheels off the ground, turn lock-to-lock slowly with the engine off, top up, then repeat with the engine running. Don’t hold the wheel on full lock for more than a couple of seconds.
• Use the correct fluid: Nissan Power Steering Fluid or an equivalent Dexron III ATF as specified in the owner’s manual. Mixing random fluids is a bad move.
• If there’s metal sparkle or black sludge in the fluid, consider pump and rack health checks—hoses fail, but contamination often has a root cause.

Common signs it’s time: red ATF spots under the ute, a whining pump on cold start or when turning, heavier-than-usual steering, or a burnt-fluid smell. Catching a tired hose early is far cheaper than replacing a pump and cleaning up a messy leak on the driveway.

Popular questions

What are the signs a 2017 Navara power steering hose is failing?
Look for red fluid drips near the front crossmember, damp hose sections, or a fine mist around fittings. A whining or groaning noise when turning and heavier steering effort also point to low fluid from a leak. Any fluid loss should be addressed straight away to protect the pump and rack.

Which fluid should be used in the 2017 Navara’s power steering?
Use Nissan Power Steering Fluid or an equivalent Dexron III ATF, as noted in the owner’s manual. Stick to one spec—don’t mix brands and types—and keep the fluid clean. If it’s dark, burnt-smelling, or glittery, plan on a flush and investigate for component wear.

How much does a power steering hose replacement typically cost?
Costs vary by hose (return vs high-pressure), brand, and labour time. As a guide, the return hose is usually cheaper, the high-pressure hose and its sealing hardware cost more and take longer to fit. Expect parts and labour to vary widely across Australia and New Zealand—getting a quote that includes fluid, new washers, and bleeding is the best way to budget.
