Genuine Mazda Upper Front Wishbone Ball Joint Rubber Boot • F151-34-541

Genuine Mazda F151-34-541 Upper Front Wishbone Ball Joint Rubber Boot

Replacement Genuine Mazda upper front wishbone ball-joint rubber boot 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 flexible rubber boot fits over the ball joint incorporated into the upper front suspension arm. It retains the joint lubricant and helps protect the ball-and-socket assembly from water, road dirt, grit and other abrasive contamination.

Maintaining an intact and securely seated boot is important for protecting the upper ball joint. A split or detached boot can allow grease to escape and contamination to enter, accelerating internal wear and corrosion.

The same boot is used on the front-left and front-right upper wishbones. This listing supplies one Genuine Mazda ball-joint boot for one side. Two are fitted per vehicle.

Replacement may be suitable where the original boot has split, punctured, hardened, distorted or become detached, provided the underlying ball joint remains smooth, secure and free from excessive play. A loose, seized, corroded or worn ball joint requires replacement of the appropriate upper suspension arm rather than the boot alone.

Fitment advice: This boot fits the upper front wishbone ball joint on either side of the MX-5 NC. Compare the boot profile, seating diameters and retaining arrangement with the removed component. Check the ball joint carefully for looseness, rough movement, corrosion or damage before fitting the replacement boot.

Other items to consider: When changing this part, you may also want to consider purchasing the appropriate upper front suspension arm, ball-joint retaining hardware, suspension-arm bushes and any fasteners showing corrosion, damaged threads or excessive wear.

Useful tools / consumables: Ball-joint separator, socket set, spanners, circlip or retaining-ring tools where required, rubber-safe joint grease, non-damaging installation sleeve, cleaning solvent, lint-free cloths and a calibrated torque wrench.

Difficulty guide: DIY Difficulty: Moderate. The upper ball-joint connection must normally be separated from the steering knuckle, and care is required to remove and install the boot without damaging its sealing lips or the joint itself.

Why Genuine Mazda? Genuine Mazda ball-joint boots are manufactured to the intended profile, rubber specification, sealing diameters and articulation range. Using the correct OE boot helps provide secure seating and suitable movement while protecting the original suspension joint.

Installation notes: Clean the ball joint and surrounding area before removing the original boot.
