RIDEX 654W0306 Front Wheel Hub & Bearing – MX-5 Mk1 NA / Mk2 NB Without ABS
Replacement RIDEX front wheel hub and integrated bearing assembly for Mazda MX-5 Mk1/NA and Mk2/Mk2.5 NB/NB-FL models without ABS.
Important fitment condition: This hub is specifically for vehicles without ABS. ABS-equipped MX-5 models require a different hub assembly.
The front hub and bearing assembly supports the road wheel and allows it to rotate smoothly while carrying vehicle, braking and cornering loads. A worn bearing can cause humming, rumbling, excessive wheel play, vibration or roughness when the wheel is rotated.

MX-5 fitment: MazSpec confirms 654W0306 for all Mazda MX-5 Mk1/NA and Mk2/Mk2.5 NB/NB-FL models from 1989–2005 where ABS is not fitted. This covers 1.6 and 1.8 applications, including later 1.8 VVT and Turbo variants, subject to the same non-ABS requirement.
Common replacement reasons: Humming or droning that increases with road speed, wheel-bearing play, roughness when rotating the wheel, vibration, abnormal tyre wear or deterioration identified during brake and suspension servicing.
Other items to inspect: Check the opposite front hub and bearing, brake discs and pads, suspension ball joints, track-rod ends and wheel studs while the hub assembly is removed.
Useful tools / consumables: Socket set, breaker bar, torque wrench, penetrating fluid and suitable tools for removing the original hub assembly and cleaning the mounting surfaces.
Difficulty guide: DIY Difficulty: Moderate to Advanced. Wheel hub replacement involves safety-critical brake, steering and suspension components.
Why RIDEX? RIDEX wheel-bearing components provide a cost-effective aftermarket replacement manufactured for the supported OE application. This assembly combines the front wheel hub and bearing and is supplied with wheel studs fitted.
What’s in the box: One RIDEX 654W0306 front wheel hub and bearing assembly with wheel studs, suitable for one front wheel.
Installation notes: Confirm that the vehicle does not have ABS before installation. Raise and support the vehicle securely and dismantle the wheel, brake and hub components in accordance with the Mazda workshop procedure. Clean and inspect the mounting surfaces before fitting the new assembly. Tighten all brake, suspension and wheel fasteners to the applicable Mazda torque specifications and confirm smooth, play-free rotation before road use.
