Genuine Mazda Rear Wheel Hub • NE51-26-240A

Genuine Mazda NE51-26-240A Rear Wheel Hub

Replacement Genuine Mazda rear wheel hub for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models with 1.8L and 2.0L petrol engines from 2005/2006 to 2015 listed in the compatibility table.

The rear wheel hub fits within the press-fit rear wheel bearing and provides the mounting flange for the road wheel and brake disc. It rotates within the bearing while transferring vehicle load, braking force and drive torque between the wheel and rear axle assembly.

The hub shaft forms the inner mounting surface for the wheel bearing, while the outer flange supports the brake disc and wheel. Accurate hub dimensions and minimal runout are essential for correct bearing fit, smooth wheel rotation and consistent brake-disc alignment.

The same hub is used on the left- and right-hand rear sides. This listing supplies one Genuine Mazda rear wheel hub for one side. Two hubs are fitted per vehicle.

Replacement may be required where the original hub shaft, bearing-contact surface, wheel-mounting flange or wheel-stud holes have become worn, scored, corroded or distorted. A damaged hub can contribute to wheel-bearing movement, vibration, brake-disc runout, uneven bearing wear or difficulty obtaining the correct bearing fit.

Fitment advice: Confirm that the rear wheel carrier retains the original Mazda separate hub and press-fit bearing arrangement. Inspect the original hub dimensions, bearing-contact surface and wheel-stud configuration before installation. A hub with scoring, corrosion or wear where it passes through the bearing should not normally be reused with a new bearing.

Other items to consider: When changing this part, you may also want to consider purchasing the Genuine Mazda FB01-26-151F rear wheel bearing, bearing retaining circlip, rear hub nut, wheel studs, brake-disc retaining hardware and any suspension fasteners disturbed during removal.

Useful tools / consumables: Hydraulic press, correctly sized hub and bearing supports, bearing separator or hub puller, circlip pliers, socket set, breaker bar, calibrated torque wrench, penetrating fluid and suitable corrosion protection for exposed mating surfaces.

Difficulty guide: DIY Difficulty: Advanced. The rear wheel carrier normally requires removal or substantial dismantling. The hub and bearing must be separated and installed using a suitable hydraulic press and correctly sized supports.

Why Genuine Mazda? Genuine Mazda wheel hubs are manufactured to the intended bearing fit, flange dimensions, wheel alignment and brake-disc mounting tolerances. Using the correct OE hub helps maintain proper bearing support, minimal runout and compatibility with the original Mazda wheel carrier, bearing, brake disc and wheel-mounting hardware.

What’s in the box: One Genuine Mazda rear wheel hub, part number NE51-26-240A. The rear wheel bearing, retaining circlip, hub nut, wheel studs and other installation hardware are not included unless specifically shown or stated separately.

Installation notes: Inspect the wheel carrier bore and all hub and bearing mating surfaces before assembly. When pressing the hub into the bearing, support the bearing's inner race correctly so that installation force is not transferred through the rolling elements. Replace specified locking hardware, tighten the hub and suspension fasteners to the applicable Mazda specifications, and confirm that the completed hub rotates smoothly without play or excessive runout.
