Fitment advice: For the Mazda MX-5 NC, this kit is used at the rear axle and can be fitted to either side. One kit services one wheel, so order two kits when replacing both rear wheel bearings.

Common replacement reasons: Humming, rumbling or droning that increases with road speed, excessive wheel play, roughness when rotating the wheel, bearing noise when cornering or deterioration identified during brake or suspension servicing.

Other items to consider: Inspect the opposite rear wheel bearing, driveshaft splines, hub, ABS components, brake discs and pads, wheel studs and surrounding suspension components while the assembly is dismantled.

Useful tools / consumables: Socket set, breaker bar, torque wrench, bearing press or suitable bearing removal/installation equipment, circlip pliers, penetrating fluid and suitable cleaning equipment.

Difficulty guide: DIY Difficulty: Advanced. This is a press-fit wheel bearing and correct removal and installation equipment is required. The bearing, circlip and driveshaft locking nut must all be installed correctly.

Why RIDEX? RIDEX wheel-bearing components provide a cost-effective aftermarket replacement manufactured to application-specific dimensions. This complete service kit includes the bearing and principal retaining hardware needed for the repair.

What’s in the box: One RIDEX 654W0425 wheel bearing, one retaining circlip and one main driveshaft locking nut. One kit services one rear wheel.

Installation notes: Securely raise and support the vehicle before dismantling the rear hub assembly. Remove the existing bearing using appropriate pressing equipment and clean and inspect the hub and bearing housing before assembly. Install the new bearing squarely without transmitting installation force through the incorrect bearing race, fit the supplied circlip and use the new driveshaft locking nut. Tighten all drivetrain, brake and wheel fasteners to Mazda's specified torque values and check for smooth, play-free rotation before returning the vehicle to service.
