Parts for your 2021 Ford Fiesta-Rack boots

2021 Ford Fiesta rack-boots (steering rack gaiters/bellows) — what they do and when to replace them

Yes, the 2021 Ford Fiesta is fitted with steering rack boots (also called gaiters or bellows). Technical documentation confirms this: the Ford Workshop Manual for the Fiesta Mk8 (2017–2023) shows bellows-type rack boots at each end of the electric power-assisted steering (EPAS) rack, and Ford’s parts catalogues (ETIS/Microcat) list the steering gear boot as a service part for these models. Third-party manuals such as the Haynes guide for the Mk8 Fiesta also reference inspection and replacement of the steering rack gaiters.

On the 2021 Fiesta, rack-boots seal the inner tie rods and the ends of the rack-and-pinion, keeping out water, dust and road grit while retaining grease around the inner joints. Even though the Fiesta uses EPAS (so there’s no power steering fluid reservoir), torn boots can still let in moisture that corrodes the rack bar and wears the inner tie-rod joints, leading to play, noise and premature steering gear damage.

As part of normal servicing in Australia and New Zealand, these boots should be inspected at every service interval (typically 12 months or around 15,000 km). Tell-tale signs they need attention include visible splits or perishing, grease flung onto the subframe, a damp/dirty inner tie rod, light knocking over bumps, heavier-than-usual steering, or a WoF/regro/MoT-style defect note for “split steering gaiter”.

If replacement is needed, it’s a straightforward job for a competent tech: the outer tie rod end is removed, the old boot and clamps come off, and a new boot is fitted with fresh clamps. Best practice is to:

• Use quality boots and proper ear/steel clamps, not cable ties.
• Lightly grease the inner joint per workshop guidance and keep any breather path clear.
• Mark tie-rod thread position but book a wheel alignment afterward, as toe can shift.
• Avoid twisting the rack, keep the steering locked straight during the job.

Leaving a split boot will almost always cost more later. Replacing boots promptly protects the EPAS rack, preserves steering feel, and helps the Fiesta sail through its next inspection without drama.

Popular questions about 2021 Ford Fiesta rack-boots

Do all 2021 Ford Fiestas have rack-boots?
They do. Regardless of trim (including ST), the car uses an EPAS rack-and-pinion with bellows-style boots on both ends. The boots are a normal wear-and-tear item listed in Ford service information and parts catalogues.

How often should the rack-boots be replaced?
There’s no fixed kilometre-based interval. They’re inspected at each service and replaced if split, perished, loose, or contaminated. Many last years, but harsh road grit or UV exposure can shorten their life. If one side has failed, the other is often close behind.

Do you need a wheel alignment after replacing the boots?
Yes, it’s strongly recommended. Even when the tie-rod end is carefully refitted to the same position, small changes can alter toe. A post-repair alignment keeps the Fiesta tracking straight and protects tyre life.
