Parts for your 2018 Ford Fiesta-Steering bushes

2018 Ford Fiesta steering bushes — what they do and when to replace them

Based on Ford’s Workshop Manual for the Fiesta (EPAS rack-and-pinion, WSM section 211‑02) and the Ford Global Parts Catalog/Microcat listings for “steering gear insulator/mount,” the 2018 Ford Fiesta (Mk8) does use steering bushes. These rubber insulators mount the electric power steering rack to the front subframe. Haynes service information for late-model Fiesta also notes rack-to-subframe isolation to control NVH, confirming the presence and role of these bushes.

On this model, the bushes isolate road harshness and engine vibration from the steering wheel while keeping the rack precisely located. When they’re healthy, the car tracks straight, feels planted, and the steering input is crisp. As they age or cop a hiding on rough Aussie and Kiwi roads, the rubber can harden, crack or deform, letting the rack shift slightly under load.

Typical signs the steering bushes are on the way out include:

• A dull clunk or knock from low in the dash/subframe over sharp bumps or when toggling the wheel at parking speeds
• Vague or wandering steering on the motorway and a faint shimmy over corrugations
• Minor but persistent alignment drift after recent wheel alignment

There’s no fixed replacement interval, but a quick look every service (or roughly each 15,000 km) is smart. A tech will load the rack with a pry bar and watch for mount movement or split rubber. If they’re perished, replace them sooner rather than later to protect tyres and the rack.

Replacement on the 2018 Fiesta commonly involves supporting the driveline and partially lowering the front subframe to access the rack mounts. Expect a wheel alignment afterwards. Ford often specifies new subframe and rack fasteners (many are torque-to-yield), correct torque/angle settings, and observing bush orientation marks—so following the WSM is key. Some VIN ranges sell the insulators separately, others push you towards a complete rack if the bushes are bonded. Aftermarket polyurethane kits exist and can sharpen steering feel, but they may add a touch more NVH compared with OE rubber.

If the steering feels loose, don’t leave it—fresh bushes bring back that tidy Fiesta turn-in Aussies and Kiwis love, and keep the EPAS rack happy for the long haul.

Popular questions

Does a 2018 Fiesta actually have steering bushes?
Yes. The EPAS rack is isolated from the subframe with rubber insulators (often listed as “steering gear mounts/insulators” in Ford parts catalogues). Depending on the exact build, they may be serviceable as separate parts or integrated with the rack.

How do I know the steering bushes need replacing?
Listen for a knock over potholes or while rocking the wheel at low speed, watch for a light shimmy and vague centring, and check if alignments don’t seem to “hold.” A workshop can confirm by loading the rack and inspecting the mounts for cracks or excessive movement.

What does replacement involve and what will it cost?
Most jobs need the front subframe loosened or partially dropped, new fasteners, and a post-repair alignment. Labour is typically a few hours. Bush kits vary in price, a full rack (if bushes aren’t sold separately) is obviously more. Expect alignment on top. Local rates in AU/NZ and your Fiesta’s VIN-spec will set the final tally.
