Related items to inspect: Check the opposite front wheel bearing, brake discs and pads, CV joints, driveshafts, ABS wiring and sensors, wheel studs and front suspension joints while the hub area is dismantled.

Useful tools / consumables: Suitable socket set, breaker bar, torque wrench, penetrating fluid, hub-removal equipment where necessary and cleaning equipment for the hub mounting surfaces.

Difficulty guide: DIY Difficulty: Advanced. Front hub replacement involves safety-critical braking, suspension and driveshaft components, and all fasteners must be tightened to the correct manufacturer specifications.
