Genuine Mazda Rear Suspension Trailing Arm / Trailing Link • N243-28-200

Genuine Mazda N243-28-200 Rear Suspension Trailing Arm / Trailing Link

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

The rear trailing arm connects the rear hub carrier to the rear subframe and helps control the fore-and-aft position of the rear wheel as the suspension moves under acceleration, braking and cornering loads. Its original dimensions and integrated rubber bushes contribute to stable handling, controlled suspension movement and correct rear-wheel alignment.

This listing is for one complete Genuine Mazda rear trailing arm with its factory-installed bushes. The same part is used in the corresponding rear left or rear right position, with two normally fitted per vehicle.

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 trailing-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, adjoining rear suspension links, eccentric alignment hardware and any corroded hub-carrier or subframe fixings 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 component helps retain factory wheel location, suspension movement, alignment range, handling balance and compatibility with the surrounding Mazda suspension components.

What’s in the box: One Genuine Mazda rear suspension trailing arm / trailing link with factory-installed bushes, part number N243-28-200. Mounting bolts, nuts and alignment hardware are not included unless listed separately.

Installation notes: Support the 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.
