Genuine Mazda Lower Front Wishbone Ball Joint Rubber Boot • F151-34-551

Genuine Mazda F151-34-551 Lower Front Wishbone Ball Joint Rubber Boot

Replacement Genuine Mazda lower 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 lower 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 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 lower wishbones. This listing supplies one Genuine Mazda ball-joint boot for one side. Two are fitted per vehicle.

Replacement may be appropriate 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 suspension component rather than the boot alone.

Fitment advice: This boot fits the lower 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 a replacement boot.

Other items to consider: When changing this part, you may also want to consider purchasing the appropriate lower 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 grease, non-damaging installation sleeve, cleaning solvent, lint-free cloths and a calibrated torque wrench.

Difficulty guide: DIY Difficulty: Moderate. The 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.
