2017 Ford Fiesta control arms — what they do and when to replace them
Based on technical sources, the 2017 Ford Fiesta does use control arms. The Ford Workshop Manual (Front Suspension, 204-01) specifies a MacPherson strut front end with a lower control arm incorporating a ball joint and two bushings. Ford’s own parts catalogues and common aftermarket listings (e.g., MOOG, Monroe, Repco) also list complete front lower control arms and bushings for the 2017 Fiesta. The rear of most 2017 Fiesta variants uses a torsion-beam axle, so there aren’t separate rear upper/lower control arms there.
On a 2017 Fiesta, the front lower control arms locate the wheel hub and strut relative to the subframe, keeping steering geometry stable and ride quality tidy. Each arm pivots on two bushings and links to the steering knuckle via a ball joint. When those bushings soften, crack or split, the car can wander, brake shimmy can creep in, and tyre wear accelerates. If the ball joint develops play, expect clunks over bumps and vague steering feel.
As part of regular servicing, it’s smart to inspect the control-arm bushings and ball joints every 20,000–30,000 km or at each major service. Look for torn or leaking (hydraulic) bushes, perished rubber, off-centre bushing sleeves, and split ball-joint dust boots. Any looseness when levering the arm or detectable play in the ball joint calls for replacement. Many owners opt to swap the entire arm rather than pressing in new bushes, as complete arms are often cost-effective and save time.
Replacement tips for a Fiesta are straightforward but there are a few must-dos:
- Always torque the bushing bolts at normal ride height to avoid pre-loading the bushes.
- Use new stretch bolts/nuts where specified by Ford, they’re designed for single use.
- Book a wheel alignment immediately after arm or bushing work to protect your tyres.
- Avoid hammering on the ball-joint stud, use the proper separator to protect the knuckle.
Workshop time typically runs about an hour or so per side, depending on corrosion and tooling. If one side has failed, the other is often close behind, so replacing in pairs can restore steering feel in one hit. Exact torque values and any model-specific steps vary by engine and trim, so it’s best to follow the Ford Workshop Manual or a quality data source (e.g., Autodata or Haynes) for the correct specs. Treat the control arms well, and the Fiesta will track straight, steer crisply, and keep its tyres wearing evenly.
Popular questions
How long do control arm bushings last on a 2017 Fiesta?
In typical Aussie and Kiwi conditions, original bushes can last 80,000–150,000 km, but rough roads, kerb hits and aggressive driving shorten that. Watch for steering shimmy, uneven tyre wear and thuds over speed bumps — they’re the early clues it’s time.
Do you need an alignment after replacing control arms?
Yes. Even if the replacement looks spot-on, the Fiesta’s camber and toe can shift slightly when the arm comes out and goes back in. A fresh alignment protects tyre life and brings the steering back to centre.
Can you just replace the bushings, or is a complete arm better?
Both approaches work. Pressing in quality bushes is fine if you’ve got the tools, but a complete arm (with pre-fitted bushes and ball joint) saves time and often comes with a warranty. Many workshops prefer complete arms for consistency and reduced labour.
