Parts for your 2012 Ford Transit-Wheel hubs

2012 Ford Transit wheel-hubs: purpose, servicing and replacement advice

Wheel-hubs are absolutely fitted to the 2012 Ford Transit (Mk7, 2006–2013). Ford’s Workshop Manual and ETIS/Microcat parts catalogue list bolt-on front hub assemblies with integrated bearings and ABS encoders, and matching hub arrangements at the rear depending on driveline (FWD or RWD). Independent references such as the Haynes Ford Transit Diesel 2006–2013 manual and Autodata service information also specify hub/bearing units and related service procedures for this model year.

On a 2012 Transit, the wheel-hub is the bit that ties it all together: it’s the mounting face for the wheel, it houses the wheel bearing to support radial and axial loads, and on ABS-equipped models it carries the tone ring or magnetic encoder for the wheel speed sensor. In day-to-day terms, the hub keeps the wheel running true, quietly and safely at highway kilometres with a full load on board.

Most Transits in this era use sealed hub-and-bearing units at the front, and either sealed units or serviceable hub bearings at the rear depending on whether it’s FWD or RWD. Sealed units aren’t designed for greasing, they’re replaced as an assembly when they wear out. Serviceable rear hubs (common on some RWD axles) use tapered roller bearings that need correct preload and fresh seals when overhauled.

Typical clues a hub is on the way out include a humming or growling that rises with speed, play when rocking the wheel at 12 and 6 o’clock, ABS warning lights, or uneven tyre wear. Left unchecked, a worn hub can cook the bearing, damage the sensor, and chew out tyres.

For routine servicing, a tech will check for play and noise, inspect ABS sensor wiring and gaps, and make sure wheel nuts have been torqued correctly. If replacement is needed, it’s worth choosing quality hub units with the correct ABS encoder polarity for the Transit’s system. New single-use fasteners (like hub nuts and certain bolts) should be fitted and torqued to Ford specifications. On RWD rear hubs, plan for new oil seals and correct bearing preload, if axles need to come out, diff oil should be checked and topped up. While hubs don’t demand frequent attention, a quick check at each service can save bigger headaches down the track—especially for vans doing big kilometres across Aus and NZ.

• Listen for speed-related droning
• Check for wheel play and roughness
• Confirm ABS sensor condition and operation

Popular questions

What are the common signs of a failing wheel-hub on a 2012 Transit?

Drivers often notice a droning or rumbling that gets louder with speed, a slight vibration through the floor, or an ABS light triggered by a damaged encoder. A quick check for free play at the wheel and roughness when spinning by hand usually confirms it.

Do the hub bearings need greasing during a service?

Most 2012 Transit front hubs are sealed units, so there’s no greasing—if they’re noisy or loose, replace the assembly. Some RWD rear hubs are serviceable, those can be cleaned, re-greased and set to the correct preload when overhauled, with new seals fitted.

Should wheel-hubs be replaced in pairs?

It’s not mandatory, but if one side has failed due to age and kilometres, the other side often isn’t far behind. Many workshops recommend doing both fronts or both rears together to keep noise and wear consistent and to minimise downtime.
