Genuine Mazda N243-28-500 Rear Lateral Suspension Arm – RH

Replacement Genuine Mazda right-hand rear lateral suspension arm for Mazda MX-5 Mk4 / ND and RF models from 2015 onward listed in the compatibility table.

This lateral arm forms part of the multi-link rear suspension and connects the right rear hub carrier to the rear subframe. It helps control rear-wheel location and suspension geometry as the vehicle accelerates, brakes and corners.

This listing is for one complete Genuine Mazda right-hand rear lateral suspension arm with its factory-installed bushes. There is one N243-28-500 arm fitted per vehicle, on the right rear only.

Replacement may be required where the original arm has become bent following impact damage, heavily corroded or has worn, split or deteriorated bushes. Possible symptoms include rear suspension knocking, unwanted wheel movement, unstable handling, uneven tyre wear or difficulty achieving and retaining the correct wheel alignment.

Fitment advice: Match the original right-hand suspension-arm position and mounting arrangement before installation. Inspect the adjoining hub-carrier and subframe mounting points, bolts, nuts and alignment hardware while the suspension is dismantled. For imported, modified or previously repaired cars, matching the original part number and component arrangement is recommended.

Other items to consider: When changing this part, you may also want to consider purchasing new suspension-arm bolts and nuts, the corresponding left-hand arm where both sides are worn, adjoining rear suspension links and any corroded hub-carrier or subframe hardware disturbed during the repair.

Useful tools / consumables: Vehicle lift or suitable jack and axle stands, suspension support equipment, socket and spanner set, breaker bar, calibrated torque wrench, penetrating fluid, alignment markers and suitable anti-corrosion treatment for surrounding components.

Difficulty guide: DIY Difficulty: Moderate to Advanced. Corroded suspension hardware can be difficult to remove, and the rear hub carrier must be supported correctly. A complete four-wheel alignment should be carried out after installation.

Why Genuine Mazda? Genuine Mazda suspension arms are manufactured to the original arm dimensions, bush specification, mounting points and suspension geometry. Using the correct OE right-hand arm helps retain factory wheel location, alignment range, handling balance and compatibility with the surrounding Mazda suspension components.

What’s in the box: One Genuine Mazda right-hand rear lateral suspension arm with factory-installed bushes, part number N243-28-500. Mounting bolts, nuts and alignment hardware are not included unless listed separately.

Installation notes: Support the right rear hub carrier before removing the original arm and record the position of any alignment hardware. Install the mounting fasteners initially finger-tight, then tighten bush-mounted suspension bolts with the suspension at its normal operating height unless the Mazda workshop procedure specifies otherwise. Tighten all hardware to the applicable Mazda specification and complete a full four-wheel alignment after installation.
