Diagram Ref No 8

Also described as a quarter-panel splash shield, the liner sits inside the left rear wheel housing and forms a protective barrier between the rotating tyre and the vehicle body, suspension area and surrounding components.

It helps shield the inner wheel arch from:

• Stones
• Gravel
• Mud
• Water spray
• Road salt
• Dirt and debris

What This Product Does:
The rear wheel housing liner protects areas behind the wheel that would otherwise be directly exposed to debris thrown from the tyre.

Its main functions include:

• Protecting inner bodywork from stone impact
• Reducing mud and water ingress
• Helping protect nearby wiring and fittings
• Reducing dirt accumulation around the wheel housing
• Helping prevent damage to painted metal surfaces
• Reducing wheel-arch noise
• Maintaining the factory wheel-housing layout
• Helping keep surrounding components cleaner

Although it is not a structural suspension component, it provides important protection for the wheel-arch area.

Symptoms Of Wear Or Failure:
Wheel housing liners can deteriorate through impact, age, incorrect removal or tyre contact.

Common symptoms include:

• Cracked plastic
• Split or torn sections
• Missing pieces
• Damaged mounting holes
• Liner hanging down
• Rattling from the rear wheel arch
• Flapping noises at speed
• Scraping or rubbing noises
• Liner contacting the tyre
• Missing clips or fasteners
• Heavy abrasion marks
• Distorted or warped liner sections
• Excessive dirt collecting behind the panel
• Water entering areas normally protected by the liner

A liner can remain partly attached while still being too damaged to provide proper protection.

Why Replacement Matters:
A damaged or missing wheel housing liner exposes the inner wheel arch to increased contamination and impact.

Continued use may contribute to:

• Stone damage
• Paint deterioration
• Increased corrosion risk
• Dirt accumulation
• Damage to nearby wiring or fittings
• Increased wheel-arch noise
• Further damage to adjoining panels
• Loose liner sections contacting the tyre

Replacing the liner restores the protective barrier originally designed into the vehicle.
