Used Ford Mustang Steering Box

The Ford Mustang used a recirculating-ball steering box on earlier generations, but from the fifth generation (S197, 2005–2014) onwards Ford switched to rack-and-pinion steering, meaning those later cars do not have a steering box at all. If your Mustang is a fifth-generation (2005–2014) or sixth-generation (S550, 2015 onwards) car, a steering box is not the part you need — you should be looking for a steering rack instead. Only buyers with an early classic Mustang (pre-2005) should be searching for a steering box, and those are typically sourced through classic-car specialists rather than modern dismantlers. If you are unsure which steering component your car uses, confirm with the breaker against your registration before ordering.

Steering boxes were fitted to the first-generation Mustang (1964½–1973) and the second-generation Mustang II (1974–1978), where recirculating-ball steering gear was standard across the range. The third-generation Fox-body Mustang (1979–1993) and fourth-generation SN95/New Edge (1994–2004) moved to rack-and-pinion, so no steering box exists on those cars or any Mustang built after 1978. If your car falls in the 1964½–1978 window, a steering box is the correct part to search for; for anything later, ask your breaker about a steering rack instead.

First-generation Mustangs (1964½–1973) did share a broad platform, but there were engineering revisions across that span — including changes to the manual and power-assisted steering box specifications — that mean a straight swap is not guaranteed. The 1967–1968 model years also introduced a wider body with some associated steering geometry changes, which is a known boundary worth flagging. Name the exact year and specification of both donor and recipient car to your breaker, and ask them to confirm compatibility against your registration before purchase.

Engine size can be relevant here: larger-engined Mustangs — particularly those fitted with the big-block V8 — were sometimes equipped with heavier-duty power-assisted steering boxes compared with six-cylinder or small-block variants, because of the extra weight over the front axle. A box from a six-cylinder car may physically fit a V8 shell but could feel different in use, and internal components may not be identical. Always tell the breaker which engine your car has so they can match the correct specification of box.

Trim level itself does not determine steering box fitment — what matters is the generation, the model year, and whether the car was fitted with manual or power-assisted steering. A GT or Mach 1 of the same year as a base coupe would use the same steering box type, assuming identical steering-assistance specification. Confirm with the breaker whether your car has manual or power-assisted steering and quote your registration, as that is what drives the correct part selection rather than the trim name.

The 2010 Mustang is a fifth-generation S197 (2005–2014), and that generation uses rack-and-pinion steering, not a steering box — so there is no steering box to source for this car. What you are most likely looking for is a steering rack, which is a different component entirely and widely available through UK breakers for the S197 generation. Search for a Ford Mustang steering rack instead, and quote your registration to the breaker to ensure they match the correct power-assisted specification for your car.
