The short version
- The first US Transit Connect wheel bearing set is 518516 press-in front and the 512439 rear hub, 2010 to 2013.
- From 2014 the redesigned van moves to the 510110 press-in front.
- None of this touches the big Transit’s numbers; the two vans share a name and nothing else.
- Delivery duty is bearing duty: full load, city miles, every day.
Ford sold two completely different vans under one badge family, and the small one came first. If your van hauled packages before 2014, this page is yours; the full-size van has its own.
Two eras of small van
The first generation Transit Connect wheel bearing up front is the 518516 press-in kit; the rear is the 512439 bolt-on hub.
The 2014 redesign switched the front to the 510110 press-in bearing, shared with the Focus family it rode on.

Not the big Transit
The full-size Transit’s hubs split by single or dual rear wheels and share nothing with this van.
That vehicle is covered on the Transit page. Order for the van you drive, not the badge.
Fleet miles age bearings fast
These vans work loaded to the roof through stop-and-go routes, which is the hardest duty a bearing sees short of towing. A used ex-fleet Connect deserves a bearing check at purchase, not after the first highway trip.
Weight’s effect on bearing life is on the vehicle weight page, and the make overview is on the Ford page.
The fronts need a press, both eras
Either generation’s front is press work: knuckle off or on-car kit. The rear on the first van is the easy half, a bolt-on hub with the sensor included.
Press logistics are on the press-in bearing page with pricing on the press service page.
Diagnosing a Transit Connect wheel bearing
- Confirm the generation, 2013 or earlier against 2014 onward.
- Weave at speed, empty, since cargo masks the hum.
- Rock each wheel at twelve and six.
- Check service records on ex-fleet vans; bearings may already be on their second round.
- Plan the press for any front.
The routine is on the checking page.
Common questions
Which Transit Connect wheel bearing do I need?
2010 to 2013: 518516 front, 512439 rear. 2014 onward: 510110 front.
Do big Transit parts fit?
No. Different vehicle entirely, covered on its own page.
Do I need a press?
For the fronts, both generations, yes. The first van’s rear bolts on.
Why did the front change in 2014?
The van moved to the global Focus platform, bringing that family’s bearing with it.
Are ex-fleet vans a bearing risk?
They are ex-fleet everything risks. Assume hard miles and check before buying.
What fails first?
Fronts, from the combination of load and city steering. The rear hub is the durable half.
