One part, two names in the trade
A wheel hub assembly is the wheel hub unit described from the fitting side: the complete bolt-on assembly a workshop removes and replaces as one piece. Trade sources treat 'wheel hub unit' and 'wheel hub assembly' as the same part, and buyers order under both names. This page covers the hub range under the assembly wording; the family page covers it by generation.
Nothing on this page is a second range. The assemblies are the hub units of the 1,661-listing family, scoped here to what the assembly buyer asks about: what the unit includes and how the replacement is identified.
What a hub assembly includes
The assembly arrives as the bearing unit with its flange and wheel studs, and — on Gen 3 applications — the integrated ABS sensor. There is nothing to press and nothing to build up: the assembly is the corner, ready to bolt on, which is why workshops price the job by the assembly.
| Generation | Assembly includes |
|---|---|
| Gen 2 | Bearing unit, flange, wheel studs |
| Gen 3 | Gen 2 content plus integrated ABS sensor |
| Gen 4 | Gen 3 content plus integrated CV joint interface |
Ordering an assembly
Quote the OE number — assembly listings run under the same numbers as the hub family, such as 15874836 — and the generation is settled by the number. Where an order is placed by application, state whether the vehicle reads wheel speed from the hub; that one answer separates the sensor assemblies from the plain ones.
Assembly or cartridge bearing?
If the old part pressed out of the knuckle, the replacement is a cartridge bearing from the wheel bearing family, not an assembly. The comparison guide works through the distinction with the checks a buyer can run on the old part.
