What This Product Does

The flexible bellows cover the moving rack ends and inner steering joints. They help exclude road grit and moisture while accommodating steering movement and keeping lubrication protected.

Functions

• Shield the covered steering components from contamination.
• Accommodate movement as the steering operates.
• Help protect lubricated inner joints from moisture exposure.

Symptoms of Fault

• Visible cracking, punctures or tears in the bellows.
• Loose attachment or contamination around the gaiter ends.
• Moisture or dirt found beneath the protective cover.
• Knocking where an exposed inner joint has developed wear.

Steering noise or looseness can have several causes. Inspect the rack and joints rather than assuming a replacement gaiter will resolve existing mechanical wear.

Why Replacement Matters

A damaged or poorly secured gaiter leaves the covered components exposed to water and abrasive debris. Renewing it restores the protective barrier, but cannot repair a worn joint or leaking rack. Check the inner joint and attachment points during the work.

FAQs

Will this fit every listed vehicle?
Confirm the installed rack reference: this kit is intended for the early rack specification.

Is alignment needed afterwards?
Have the wheel alignment checked if track rods are disturbed or their adjustment changes.

What should be inspected with the gaiter removed?
Check for inner-joint play, contamination and signs of rack leakage before fitting the replacement cover.
