Parts for your 2015 Ford Fiesta-Rack boots

2015 Ford Fiesta (WZ): Are rack boots used, and what should owners know?

Yes — the 2015 Ford Fiesta (WZ, AU/NZ) uses rack-and-pinion steering with a bellows-style rack boot (also called a steering rack gaiter) on each side. This is documented in the Ford Workshop Manual for Fiesta 2013–2017, Section 211-02 Steering System (exploded diagrams show “steering gear boot” on both ends of the rack), the Ford/Motorcraft and Microcat parts catalogues for WZ models (listing a “Boot — Steering gear”), and the Haynes Ford Fiesta 2008–2017 manual, which includes inspection and replacement of steering gaiters. Even with electric power-assisted steering (EPAS), the Fiesta still has inner tie-rods and a rack that rely on boots to keep contaminants out.

On this Fiesta, the rack boots do a simple but vital job: they seal the ends of the steering rack, keeping dust, road splash, and grit out while letting the inner tie-rods articulate. If a boot splits or its clamp loosens, water and grit can work their way in, chewing out the inner tie-rod joints and potentially the rack itself. Left long enough, it can cause play in the steering, knocks over bumps, and moisture damage — and it’s the sort of thing that can attract a WOF/RWC fail.

Good servicing practice is to eyeball the rack boots at every regular service (typically 10,000–15,000 km or 12 months). Look for perishing, cracks, oil or grease on the outside of the boot, loose or missing clamps, or any tell-tale wetness after driving in rain. A quick wipe and torch check with the wheels turned side-to-side makes inspection easier.

If a boot is damaged, replace it promptly — ideally both sides at once. Use quality boots that match the Fiesta’s rack, fit new clamps, and avoid twisting the bellows when refitting. After any inner tie-rod or boot work, a wheel alignment is a must. On EPAS cars, follow the Ford workshop procedure and torque specs, if the inner tie-rod’s been disturbed, many shops will perform a basic steering centre/EPAS reset as part of the alignment workflow.

Owners can help rack boots last by avoiding deep water crossings, rinsing road salt or beach sand off the underbody, and getting small weeps or leaks checked early. It’s a small, inexpensive part that protects a much pricier steering rack — the kind of preventative care that keeps the Fiesta feeling tight and tidy on Kiwi and Aussie roads.

• Inspect at each service interval
• Replace in pairs if one has failed
• Fit new clamps and book a wheel alignment

Popular questions about 2015 Ford Fiesta rack boots

Do rack boots differ between EPAS and non-EPAS Fiestas?
They serve the same purpose and look similar, but the boot profile and length can vary with the specific steering rack. Always match by VIN or rack number via a Ford parts catalogue or a reputable supplier.

How can someone tell a rack boot needs replacing?
Common signs include visible splits or cracks in the bellows, grease flung onto nearby suspension or the inside of the wheel, dampness after rain, and light knocking over bumps. Any play noted at a service inspection can also point to inner tie-rod wear from a compromised boot.

Will a torn rack boot affect a WOF/RWC?
Yes. A torn or unsecured boot that allows contaminants into the steering gear is grounds for a fail. Replacing the boot and confirming no excessive steering play, then completing an alignment, typically resolves the issue.
