Vauxhall Cavalier Differential Replacement Parts

The Cavalier ran as the Mk3 from 1988 to 1995, and differentials within that generation are most likely to be compatible, but the key detail is matching the engine code rather than the year alone, since Vauxhall used different final-drive ratios across the engine range. Check your engine code on your V5 or a VIN check and give it to the breaker, as a diff from a 1989 car could suit a 1994 car if the engine codes align, or could be wrong if they differ. Never assume fitment on year alone — confirm against your registration with the breaker.

No, not reliably — the 1.8 and 2.0 engines used different final-drive ratios in the differential, so a unit from one engine family will not necessarily be correct for the other. The engine code is the single most useful detail here, so check your V5 or run a VIN check before approaching a breaker. Always confirm the specific engine code match with the breaker rather than relying on engine size alone.

Body style does not affect differential fitment on the Cavalier — the differential follows the drivetrain and engine code, not the body. What matters is your engine code, fuel type, and whether the car is manual or automatic, so give those details to the breaker rather than worrying about body style. A unit pulled from a hatchback can be correct for an estate if the mechanical specification matches.

Trim level does not determine differential fitment — a GL, CDi, and SRi sharing the same engine code and gearbox type would use the same differential. The SRi often used sportier engine variants, so the engine code may differ from a base GL even if the displacement sounds similar, which is why the engine code from your V5 is the reliable starting point rather than the trim badge. Confirm the engine code match with the breaker and note that ancillary brackets or mounting details can vary mid-production, so ask the breaker to check those against your registration.

The Cavalier Mk3 ran through to 1995 when it was replaced by the Vectra, so a 1994 and a 1995 Cavalier are within the same generation and are the most straightforward candidates for interchange. That said, Vauxhall made running production changes throughout the Mk3's life, so matching the engine code remains essential, and ancillary or mounting details should be confirmed with the breaker against both registrations rather than assumed identical. Give the breaker both the donor and recipient engine codes for the most reliable answer.

Diesel and petrol Cavaliers used different drivetrain specifications, and the differentials are not interchangeable between fuel types as a rule. Always specify your fuel type and engine code when contacting a breaker, as these are the two most important filters after confirming gearbox type. A breaker with access to the original parts data will be able to confirm compatibility against your specific registration.
