Parts for your 2018 Subaru Exiga-Wheel hubs

2018 Subaru Exiga wheel hubs

Wheel hubs are absolutely relevant and fitted to the 2018 Subaru Exiga. Technical sources such as the Subaru Factory Service Manual (FSM) for the Exiga/Crossover 7 (Front Axle and Rear Axle sections) specify bolt-on hub unit bearings at each corner with integrated wheel studs and ABS encoder rings. Subaru’s official electronic parts catalogues (FAST/Microcat) also list complete front and rear hub assemblies for the 2018 model, confirming the design and service approach.

On the 2018 Exiga, the wheel hubs do the heavy lifting behind the scenes. Each hub unit supports the vehicle’s weight via a sealed bearing, locates the wheel with press-fitted studs, interfaces with the brake rotor, and provides the encoder signal for the ABS/vehicle dynamics system. Being a sealed “hub unit bearing”, it’s maintenance-light: there’s no regreasing schedule, and when wear sets in, the whole assembly is replaced rather than rebuilt.

Owners will usually first notice a worn hub as a low, speed-dependent humming that changes on gentle steering input, a faint vibration through the cabin, or play when rocking the wheel at the 12 and 6 o’clock positions. An illuminated ABS light or erratic speed readings can also stem from a damaged encoder ring in the hub. Tyre roar can mimic hub noise, so a proper road test and on-hoist inspection are smart before ordering parts.

During servicing, a technician should check for bearing play, roughness when the wheel spins, uneven tyre wear, and any ABS faults. If replacement’s on the cards, the Exiga’s hub units are designed to unbolt from the knuckle, with the driveshaft passing through the front hubs. Good practice includes: cleaning the mating face so the new hub sits perfectly square
