2007 Subaru Impreza wheel-hubs: what they do and how to look after them

Wheel-hubs are absolutely used on the 2007 Subaru Impreza. Technical sources such as the Subaru Factory Service Manual for MY2007 Impreza (Chassis/Suspension and Drive Shaft sections) and genuine Subaru parts catalogues identify bolt-on hub unit bearings at each corner, with the front hubs supporting the drive shafts and the rears carrying the wheel and brake assemblies. These hub units incorporate sealed bearings and, on ABS-equipped models, an integrated encoder/tone ring for wheel-speed sensing. Aftermarket service data from recognised workshop information systems also depicts the Impreza’s hub as a complete assembly that’s replaced as a unit rather than serviced internally.

The sealed bearing inside the hub carries the vehicle’s weight and handles both radial and axial forces, while the hub flange provides a flat, secure mounting face for the brake rotor and wheel. Up front, the hub splines to the CV axle so engine torque is transferred to the tyres
