Used wheel hubs vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
The Cavalier ran through three main generations: Mk1 (1975–1981), Mk2 (1981–1988), and Mk3 (1988–1995), and wheel hubs are not generally interchangeable across these generation boundaries due to changes in suspension geometry and brake sizing. Within a single generation you have the best chance of a direct swap, but confirm the exact year and engine size with the breaker against your registration before ordering.
Both years fall within the Mk3 generation (1988–1995), so there is a reasonable chance of compatibility, but Vauxhall made mid-generation updates to the Cavalier's running gear and brake specifications during this period. Whether a specific hub from 1989 crosses those mid-generation changes to suit a 1993 car is something you should confirm with the breaker against your registration number to be sure.
Yes, engine size can matter because larger-engined Cavaliers — particularly the 2.0-litre variants — were often fitted with larger brakes, which can mean a different hub to smaller-engined versions of the same year. Always tell the breaker your engine size as well as the year and generation so they can match the correct hub to your car.
Trim level itself does not determine which wheel hub is fitted — what matters is the generation and engine size, not whether the car is a base L, GL, GLS, or SRi. That said, an SRi typically carried a larger engine than a GL, so the engine-size difference between trims is the real factor to check rather than the trim name itself; confirm the engine size with your breaker.
For most standard hub assemblies the same part fits both sides, but if the hub includes an ABS reluctor ring or the bearing flange is directional, NS (nearside/left) and OS (offside/right) can differ. Check with the breaker whether the specific hub they have is side-specific before you commit to the purchase.
The Mk2 (1981–1988) and Mk3 (1988–1995) Cavalier have different suspension and braking setups, so a hub from a Mk2 is very unlikely to be a straight swap onto a Mk3 without modification. This is a known generation boundary where fitment should not be assumed — route this directly to the breaker and give them both registration numbers so they can compare the parts accurately.
