Parts for your 2013 Ford Fiesta-Wheel bearings

2013 Ford Fiesta wheel bearings — purpose, care, and when to replace

Wheel bearings are absolutely used on the 2013 Ford Fiesta. Technical references such as the Ford Workshop Manual (WSM) for WT/WZ Fiesta and Motorcraft parts catalogues specify sealed, unitised hub bearings at each corner. Up front, the Fiesta uses a press-in, double-row ball bearing installed in the steering knuckle with a separate hub, and at the rear it typically runs a bolt-on hub assembly with an integrated bearing (disc-brake ST models also use a sealed rear hub/bearing). These bearings are non-serviceable: when worn, they’re replaced rather than repacked.

On this Fiesta, wheel bearings let the wheels spin smoothly with minimal friction while supporting the car’s weight and cornering loads. Because they’re sealed, there’s no routine greasing to do, but they still deserve a quick check during every service. A mechanic will listen for a dull growl or humming that rises with road speed, feel for play at the wheel, and spin each wheel off the ground to check for roughness. Sealed bearings last a long time, but potholes, kerb strikes, water ingress, and big wheel/tyre combos can shorten their life.

Replacement is straightforward for a pro, but it’s not a DIY Saturday job unless properly equipped. The front bearing is pressed into the knuckle and uses a snap ring, it also has a magnetic encoder that must face the ABS sensor. Get that orientation wrong and the ABS light will come on. The axle nut and many related fasteners are single-use and must be torqued to the Ford spec. At the rear, the Fiesta’s hub and bearing are replaced as one piece, again, use a new hub nut and correct torque/staking procedure. A post-repair road test and ABS scan are smart practice.

Good habits help bearings live longer: keep tyres correctly inflated, avoid deep water when hot, and don’t ignore vibration or a new road-speed whir. During routine servicing (say, every 10,000–15,000 km), a quick check for noise, heat, or looseness is enough. If a bearing is noisy or has play, replace it promptly to protect the hub, knuckle and ABS components. Using quality parts that meet OE spec, and following the Ford WSM procedures, keeps the Fiesta riding quiet and true.

• Common signs of wear: humming that changes with speed, ABS faults after impact, heat at the hub, or noticeable wheel play.
• Best practice: replace single-use nuts/bolts, press bearings squarely, protect the ABS encoder, and always torque to spec.

FAQs

How long do wheel bearings last on a 2013 Fiesta?
With normal city and highway driving, sealed bearings often run well past 100,000 km, and many go to 200,000 km or more. Harsh roads, water crossings, big impacts, or oversized wheels can bring that forward. A quick check at each service will usually spot issues early.

What are the tell-tale noises of a failing Fiesta wheel bearing?
Expect a steady humming, droning, or rumble that rises with speed and may change slightly when turning. It’s different from a tyre roar because it won’t change much with road surface. If the bearing’s encoder is damaged or installed backwards, the ABS light may also appear.

Can the Fiesta’s wheel bearings be greased or adjusted?
No—both front and rear are sealed, non-adjustable bearings. There’s no regreasing or preload adjustment. When they wear, they’re replaced as a pressed-in bearing (front) or a complete hub assembly (rear), following Ford workshop procedures and torque specs.
