Genuine Mazda Rear Anti-Roll Bar D-Bush – 2.0 Sport • NF53-28-156B

Genuine Mazda NF53-28-156B Rear Anti-Roll Bar D-Bush – 2.0 Sport

Replacement Genuine Mazda rear anti-roll-bar D-bush for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 NC 2.0 Sport models fitted with the sports suspension specification.

The rubber bush fits around the rear anti-roll bar and is retained against the rear subframe by a separate metal mounting bracket. It supports the anti-roll bar while allowing the controlled rotational movement required as the rear suspension moves.

The anti-roll bar links the movement of the left- and right-hand rear suspension. The mounting bushes locate the bar securely and isolate vibration while allowing it to twist as the vehicle corners.

Age, compression and repeated suspension movement can cause the original rubber to harden, split or become enlarged. This may allow the bar to move inside the mounting and can contribute to knocking noises or less precise rear suspension response.

The same bush fits the left- and right-hand mounting positions. Two bushes are required per vehicle, and this listing supplies one Genuine Mazda bush. Select a quantity of two when replacing both rear anti-roll-bar mounting bushes.

Important fitment restriction: NF53-28-156B is the rear anti-roll-bar bush for MX-5 NC 2.0 Sport models with the sports suspension specification. Vehicles using the standard suspension and five-speed gearbox use a different rear bush.

Possible signs of worn rear anti-roll-bar bushes:

• Knocking or tapping from the rear suspension
• Noise over small bumps or uneven road surfaces
• Visible cracking or splitting of the rubber
• Anti-roll bar movement inside the bush
• Rubber compressed or distorted around the mounting bracket
• Reduced precision from the rear suspension
• Corrosion or wear marks on the anti-roll bar beneath the bush

Fitment advice: Select this bush by suspension specification. It is intended for the sports-suspension rear anti-roll-bar arrangement used on MX-5 NC 2.0 Sport models. Do not assume that it fits every NC purely because the mounting position appears similar.

Replacement advice: Rear anti-roll-bar bushes should normally be replaced as a pair so that the bar is supported consistently on both sides. Inspect the anti-roll bar for corrosion, scoring or wear beneath the original bushes before installing the replacements.

Other items to consider: Inspect the opposite rear anti-roll-bar bush, both rear drop links, mounting brackets, bracket bolts, rear anti-roll bar and nearby suspension-arm bushes. Consider purchasing replacement brackets or fasteners where the originals are heavily corroded.

Useful tools / consumables: Vehicle lift or axle stands, socket and spanner set, calibrated torque wrench, penetrating fluid, wire brush and rubber-compatible installation lubricant where permitted by the applicable procedure.

Difficulty guide: DIY Difficulty: Moderate. The bushes are accessible from beneath the rear of the vehicle, but seized or corroded bracket bolts may require additional preparation. The vehicle must be supported safely before work begins.

Why Genuine Mazda? Genuine Mazda anti-roll-bar bushes are manufactured to match the original bar diameter, mounting-bracket profile, rubber hardness and suspension specification. Correct dimensions and material properties help locate the bar securely without preventing its intended movement.

What’s in the box: One Genuine Mazda rear anti-roll-bar D-bush, part number NF53-28-156B.

Installation notes: Raise and support the vehicle securely before working beneath the rear suspension. Clean the anti-roll-bar mounting area and apply penetrating fluid to corroded bracket bolts where necessary. Support the anti-roll bar, remove the retaining bracket and note the position and orientation of the original bush. Clean the bar and inspect it for corrosion or wear. Open the replacement bush at its split and position it around the bar in the same orientation as the original. Refit the bracket evenly without trapping or twisting the rubber, then tighten the mounting bolts to the applicable Mazda specification. Repeat on the opposite side where replacing the pair and road-test the vehicle to confirm that any suspension noise has been resolved.
