Ford Focus Differential Replacement Parts

The Focus Mk3 ran from 2011 to 2018 with a facelift in 2014, so a 2013 unit sits pre-facelift and a 2015 unit is post-facelift — they share the same generation, but whether the differential crosses that 2014 boundary without issue depends on your exact engine code and gearbox type, so confirm compatibility with the breaker against your registration. The engine code (found on your V5 or via a VIN check) is the single most useful detail you can give them. Never assume fitment without that check.

The Focus Mk2 ran from 2004 to 2011 and the Mk3 from 2011 to 2018 — these are separate generations with different platforms, so a straightforward swap is unlikely. Provide your engine code and gearbox type to the breaker, as those details will confirm whether any crossover is possible. Do not assume fitment across generation boundaries.

For the Ford Focus, trim level — whether Zetec, Titanium, or any other badge — does not determine which differential you need; what matters is the engine code, fuel type, and gearbox type. A Zetec and a Titanium sharing the same engine code and gearbox will use the same differential, so you can source from either without concern about the trim name. Just confirm the engine code with the breaker against your registration to make sure.

The most important details are your engine code, fuel type (petrol or diesel), and gearbox type (manual or automatic), as these govern differential fitment far more than the year or trim badge alone. Your engine code is printed on your V5 logbook or can be retrieved via a VIN check, and it is the single most reliable reference for the breaker. Year and generation are also useful context, but always lead with the engine code.

The Focus ST uses performance-tuned driveline components, and whether its differential is interchangeable with a standard Focus unit — even one sharing a similar engine family — is not something to assume. Confirm directly with the breaker using your full engine code, gearbox type, and registration, as ancillary and mounting specifications can vary even within the same generation. This is a case where the breaker's hands-on knowledge of the specific part is essential before purchasing.

Both a 2008 and a 2010 Focus fall within the Mk2 generation (2004 to 2011), so they are on the same platform, which is a positive starting point. Fitment still depends on matching the engine code, fuel type, and gearbox type rather than the year alone, so give those details to the breaker along with your registration. Year proximity within a generation is helpful but does not guarantee the parts are identical.
