Parts for your 2017 Ford Focus-Wheel hubs

2017 Ford Focus wheel hubs — what they do and how to look after them

Based on the Ford Workshop Manual for the 2015–2018 Focus (Front and Rear Suspension sections), the Ford Genuine Parts catalogue for MY17 Focus, and major bearing catalogues from Timken and SKF, the 2017 Ford Focus is fitted with bolt-in wheel hub and bearing assemblies at the front and rear. Some models use rear disc brakes with a separate hub assembly, while variants with rear drum brakes have the bearing integrated with the drum and hub. So wheel hubs are absolutely relevant to this model.

The wheel hub on a 2017 Focus sits at the heart of each corner, locking the wheel to the knuckle or axle and letting it spin smoothly via an integrated bearing. On ABS-equipped cars (that’s most Aussie and Kiwi-delivered Focus models), the hub normally houses the magnetic encoder ring that the ABS/ESC sensor reads. If the hub or its bearing degrades, expect humming that changes with speed, a faint grind or vibration through the cabin, or an ABS light from a dodgy encoder signal. Left too long, it can chew out tyres, impact braking performance, and get noisy enough to drive anyone up the wall.

Servicing is straightforward but benefits from the right approach. Hubs on the Focus are typically a sealed unit, so there’s no regreasing—when they’re worn, replace the assembly. Front units bolt to the steering knuckle and clamp to the driveshaft, rears bolt to the trailing arm/rear knuckle or are integrated with the drum on drum-brake cars. Always follow Ford torque specs for the axle nut and hub bolts, and use new single-use fasteners where specified. Wheel alignment isn’t usually required after a hub swap, but it’s smart to check if the knuckle was disturbed.

• Listen for a speed-dependent hum or growl that gets louder when loading one side through a sweeping bend.
• Check for play by rocking the wheel at 12 and 6 o’clock (with the car safely lifted).
• Inspect ABS wiring and clean mounting faces so the hub sits perfectly flush.
• Use quality parts that include the correct ABS encoder, mixing the wrong type can trigger warning lights.

As a rule of thumb, many Focus hubs run 100,000–200,000 km depending on roads and loads. Anyone doing regular motorway kilometres, towing, or hitting potholes should keep an ear out earlier. When it’s time, a fresh hub assembly brings back that smooth, quiet ride and keeps the tyres wearing evenly.

What are the common signs of a failing wheel hub on a 2017 Focus?

Tell-tales include a humming or droning noise that rises with speed, faint vibration, ABS/traction lights, or uneven tyre wear. The noise often changes when cornering—louder when the faulty side is loaded. With the car safely lifted, excess play when rocking the wheel can also point to a worn hub bearing.

Do the bearings get pressed out, or is it a complete hub assembly?

On the 2017 Focus, the front is a sealed hub-and-bearing unit that’s replaced as an assembly. The rear is also a bolt-in hub unit on disc-brake models, while drum-brake variants have the bearing integrated with the drum and hub. In all cases, replacement is the usual route—no pressing or regreasing.

How long do wheel hubs last and what might replacement cost in AU/NZ?

Many last 100,000–200,000 km, but rough roads, big potholes, and kerb strikes shorten that. In Australia and New Zealand, quality hub assemblies often run roughly $150–$400 each, with 1.0–2.0 hours labour per corner depending on side and brake setup. Actual pricing varies with brand, workshop rates, and model variant.
