Parts for your 2017 Ford Focus-Steering rack

2017 Ford Focus steering rack: what it does and how to look after it

According to the Ford Workshop Manual for Focus (WSM sections 211-00/211-02) and Ford’s OEM parts listings for 2017 Focus, this model is built with a rack-and-pinion Electric Power-Assisted Steering (EPAS) rack. Haynes coverage for 2011–2018 Focus models backs that up. So yes, the 2017 Ford Focus definitely uses a steering rack.

On a 2017 Focus, the steering rack turns the driver’s wheel input into precise left–right movement of the front wheels. Because it’s EPAS, the assist comes from an electric motor integrated with the rack, giving lighter steering at parking speeds and a more planted feel at highway pace. It also talks to vehicle systems like stability control and, on some trims, park assist, which rely on accurate steering torque and position data.

Day to day, there’s not much to “service” inside the rack itself—it’s a sealed unit. But there are smart checks to keep it happy during routine servicing:

• Inspect rack boots, inner and outer tie rods, and mounting bushes for play, splits or rust.
• Check wheel alignment and tyre wear, feathering or pull can hint at rack or tie-rod issues.
• Verify no water or grit has got past a torn boot—contamination kills racks quickly.
• Scan for EPAS fault codes and apply any software updates if flagged by service info.

Because it’s electric, there’s no power steering fluid to top up—if someone’s hunting for a reservoir under the bonnet, they won’t find one. Any oily residue around the area will be from something else, not EPAS fluid.

If a rack needs replacement (collision damage, excessive play, binding, EPAS warning, or clunks), plan on a proper alignment and electronic setup afterwards. Technicians should:

• Support the battery and follow Ford WSM torque specs, many fasteners are single-use.
• Centre the rack, set toe with the steering wheel straight, and perform steer-stop learn/calibration.
• Complete module programming (PMI/as‑built) if the vehicle or replacement rack requires it.

Owners will notice trouble signs like a “Steering assist fault – Service required” message, heavier or inconsistent steering feel, knocks over bumps, or rapid inner/outer tyre wear. Sorting small issues early—like a split boot or loose outer tie-rod—can save the cost of a full rack down the track.

Does the 2017 Focus have power steering fluid?

No. It uses EPAS, so there’s no hydraulic fluid or reservoir. If there’s a leak around the subframe area, it’ll be from another system, not the rack itself. Keep an eye on the rack boots, if they’re torn, get them replaced quickly to keep grit out.

How long should a steering rack last?

Many racks go well past 150,000–200,000 kilometres, but life depends on road conditions, impacts, and boot integrity. Clunks, free play, or uneven tyre wear are early signs to check tie-rods and the rack. A quality alignment and good tyres help longevity.

After replacing the rack, does it need programming or calibration?

Yes, the EPAS system may need a steer-stop learn and, depending on the part used, module setup (PMI/as‑built) with a scan tool. Always finish with a four-wheel alignment and ensure the steering wheel sits dead straight.
