2020 Ford Fiesta control arms — what they do and when to replace them
Control arms are absolutely fitted to the 2020 Ford Fiesta. Technical sources including the Ford Workshop Manual (Section 204-01 Front Suspension for the 2017–onwards Fiesta/Mk8 platform), Ford ETIS/Microcat parts catalogues (listing front lower suspension arm assemblies and bushes), and service databases such as Autodata/Haynes all specify a MacPherson strut front end with a single lower control arm (wishbone) per side. The rear of the Fiesta uses a torsion-beam axle, so there aren’t separate rear control arms.
On the front of the Fiesta, the control arm ties the wheel hub to the subframe, keeping camber and caster where Ford intended while letting the strut do the up‑and‑down work. Rubber or hydraulic bushes soak up vibration, and the ball joint lets the steering and suspension articulate smoothly. When these parts age, handling feel, tyre wear, and braking stability can all go off the boil.
Owners should keep an eye on the classic signs of wear:
- Clunks or knocks over potholes and speed humps
- Steering shimmy, tramlining, or vague on‑centre feel
- Uneven or rapid tyre wear on the front
- Brake shudder that isn’t caused by warped rotors
- Visible cracking or oil‑soaked bushes, ball joint play
As part of routine servicing, a visual check every 12 months or 20,000 kilometres is smart, especially if the Fiesta sees rough roads or heavy city duty. Bushes commonly last 80,000–150,000 kilometres, but harsh conditions can bring that forward. If one arm is tired, replacing in pairs helps keep the car tracking straight and stable. After any control arm or bush replacement, a full wheel alignment is a must — geometry changes slightly when fresh bushes are fitted.
Ford specifies torque‑to‑yield fasteners in this area on many Fiesta variants, those bolts are typically single‑use and should be replaced. Final tightening needs to be done at normal ride height to avoid twisting the new bushes. Quality matters too: OEM or reputable aftermarket arms and bushes will keep noise, vibration, and harshness low and last the distance.
- Inspect bushes and ball joints during every service, look for tears, cracks, and free play.
- Replace worn components promptly to protect tyres and brakes.
- Use new hardware where specified and torque to Ford data.
- Finish with a proper alignment and road test.
Popular questions about 2020 Ford Fiesta control arms
Does the 2020 Fiesta have rear control arms?
The rear suspension is a torsion‑beam setup, so there aren’t separate multi‑link style rear control arms. The front end is where you’ll find the control arms (one per side), complete with bushes and a ball joint.
How long do Fiesta control arm bushes last?
In normal Aussie and Kiwi driving, expect around 80,000–150,000 kilometres. Frequent corrugations, heavy loads, or lots of stop‑start can shorten that. An annual inspection will catch bush cracks or ball joint play before they affect tyres and braking.
Do you need a wheel alignment after replacing a control arm?
Yes. Fresh bushes and a new arm can nudge camber and toe, so an alignment is essential to keep steering feel crisp and prevent premature tyre wear.
