2017 Ford Focus rack-boots: what they do and when to replace them

Rack-boots are absolutely used on the 2017 Ford Focus. Technical references including the Ford Workshop Manual for Focus (2015–2018) steering system (rack-and-pinion EPAS) and Ford genuine parts catalogues list “steering gear boot/bellows” for all 2017 Focus variants. Reputable aftermarket catalogues (MOOG, Gates, Febi and similar) also specify direct-fit rack-boots for this model. So, for any 2017-ford-focus rack-boots search, the part is relevant and fitted from factory.

On this Focus, rack-boots (also called bellows or gaiters) sit on each end of the steering rack, sealing the inner tie rods and the rack from dust, water and road grit. They help retain the correct grease, keep abrasive muck away from the rack bar and seals, and stop corrosion from taking hold. Because the Focus uses electric power-assisted steering (EPAS), the boots don’t carry fluid pressure like old hydraulic systems, but a torn boot can still let contaminants in, accelerating wear and creating play or noise in the steering.

Best practice in Australia and New Zealand is to have the rack-boots checked at every service (typically 12 months/15,000 kilometres). Replace them straight away if they’re split, perished, loose on their clamps, or showing signs of water or grit inside. Driving through floods, gravel roads, track days or regular kerb strikes will shorten their lifespan.

• Signs a rack-boot needs attention: visible cracks or tears, wet, greasy or gritty build-up around the boot, clunks or play felt on steering, uneven tyre wear, or sticky steering after heavy rain.

Replacing a rack-boot on a 2017 Focus is straightforward with the right tools. The tie-rod end is removed, the old boot is slid off, the rack is cleaned, and the new boot is installed with proper clamps—skip the cable ties. Make sure the boot isn’t twisted and that it can “breathe” as the rack moves. Refit and torque the tie-rod end correctly and organise a wheel alignment afterwards, as toe settings can shift. Quality matters here: choose OE or a high-grade TPE/CR rubber boot, and consider replacing both sides if they’re the same age. Avoid harsh solvents when cleaning, and take the chance to check inner tie-rod and rack for play before buttoning it all up.

A torn rack-boot can lead to a failed WOF (NZ) or roadworthy inspection (AU), so it’s worth sorting promptly to protect the steering gear and your tyres.

FAQs

Does the 2017 Ford Focus have rack-boots?
Yes. The 2017 Focus uses a rack-and-pinion EPAS steering gear with protective rack-boots (bellows) on both ends. Ford workshop literature and parts catalogues list the boots for all key trims, and major aftermarket brands offer direct replacements.

How often should 2017 Ford Focus rack-boots be inspected or replaced?
Have them inspected at every service (about 12 months/15,000 kilometres). Replace immediately if split, loose, or contaminated with water or grit. Life varies with conditions—gravel, water crossings and kerb hits tend to shorten it.

Do you need a wheel alignment after replacing a rack-boot?
It’s highly recommended. Removing the tie-rod end to fit a new boot can alter toe. Even if you count turns and mark positions, a proper alignment saves tyres and ensures the Focus tracks straight.
