Genuine Mazda Front Lower Suspension Arm / Wishbone – RH • N243-34-300C

Genuine Mazda N243-34-300C Front Lower Suspension Arm / Wishbone – RH

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

The front lower suspension arm, also known as the lower control arm or wishbone, connects the right-hand front hub carrier to the front subframe. It supports the lower part of the steering knuckle and allows controlled suspension movement through its integral bushes and ball joint.

The arm plays an important role in maintaining front-wheel position, steering geometry and suspension alignment under braking, acceleration and cornering loads.

This listing is for one complete Genuine Mazda right-hand front lower suspension arm assembly with factory-installed bushes and ball joint. There is one N243-34-300C arm fitted per vehicle, on the front-right side only.

Replacement may be required where the original arm has become bent following kerb or impact damage, heavily corroded, or has developed excessive movement in its bushes or ball joint. Possible symptoms include front suspension knocking, vague steering, unwanted wheel movement, uneven tyre wear or difficulty achieving and retaining the correct wheel alignment.

Fitment advice: Confirm that the arm being replaced is on the right-hand front side and compare the original mounting arrangement before installation. Inspect the steering knuckle, subframe mounting points, ball-joint connection and adjoining fasteners while the suspension is dismantled.

Other items to consider: When changing this part, you may also want to consider purchasing new front and rear arm mounting bolts and nuts, the corresponding left-hand arm where both sides are worn, anti-roll-bar links, upper suspension-arm components and any other corroded or worn suspension hardware identified during inspection.

Useful tools / consumables: Vehicle lift or suitable jack and axle stands, suspension support equipment, ball-joint separator, socket and spanner set, breaker bar, calibrated torque wrench, penetrating fluid and alignment markers.

Difficulty guide: DIY Difficulty: Moderate to Advanced. The suspension must be supported correctly, the ball joint separated from the hub carrier and potentially corroded mounting bolts removed. A full wheel alignment should be completed after installation.

Installation notes: Support the hub carrier and suspension before removing the original arm. Note the location and orientation of all mounting hardware.

Tighten all fasteners to the applicable Mazda specification and complete a full four-wheel alignment after installation.
