About part number 7319759

An arch liner is a protective plastic shield mounted inside the wheel arch, positioned between the road wheel and the inner wing. It forms part of the exterior bodywork and splash protection system, guarding the inner body panels, wiring harnesses, and engine bay components from road grit, water, and debris thrown up by the tyre. When it is securely fitted and intact, the driver notices reduced road noise from the wheel well and no rattling from loose undertrays or trim.

To confirm that this part is the correct match for your vehicle, you must check the original manufacturer part number against your existing component. On a moulded plastic arch liner, the part number is usually stamped or raised directly into the plastic surface on the reverse side. Matching part number 7319759 exactly is the only way to ensure correct fitment, as shape, clip locations, and mounting points vary across different specifications.

When replacing an arch liner, a person usually needs new plastic trim clips, expansion rivets, or threaded fasteners, as the original fixings often break or strip during removal. These liners are commonly replaced after damage from kerb impacts, tyre blowouts, or contact with debris on the road, or because old plastic has become brittle and fractured around the mounting holes.

  • Part type: Splash Guards & Mud Flaps.

About this kind of part: wheel arch liners

A wheel arch liner is the moulded plastic or felted shell inside a wheel arch that keeps water, salt and stones off the inner wing, the suspension and the wiring. It is hidden and it is not structural, but it is the part that decides whether the metal behind it rusts, so a missing or torn liner is a slow problem rather than a cosmetic one. Mudflaps, undertrays and the air ducts that feed the brakes are the same kind of part doing the same job elsewhere under the car.

Why people replace one

  • The liner has torn away from its clips, usually after a wheel has picked it up at speed, and it now rubs the tyre.
  • Road debris or a kerb has split the liner along an edge.
  • The clips and screws have rusted away or pulled through, so the liner hangs down and catches.
  • The liner was removed for a repair and never refitted, which leaves the inner wing exposed.
  • A felted liner has become waterlogged and heavy and has pulled itself off its fixings.

Fitting it

  • The wheel normally has to come off, and the car must be supported properly on axle stands rather than a jack alone.
  • A liner is held by a mixture of plastic screws, clips and expanding rivets around its edge, and most of them break on removal, so a set of fixings is worth having before starting.
  • Fit the fixings loosely around the whole edge first and tighten them afterwards, otherwise the last few holes will not line up.
  • With the liner out, it is worth looking at the metal behind it. A liner that has been missing for a while has usually exposed something worth seeing.

Making sure it is the right one

  • Match the part number moulded into the liner. Front and rear differ, the two sides differ, and a model with wider arches takes a different part again.
  • Count the fixing holes and compare their positions with the old liner. This is the quickest way to tell two similar liners apart.
  • Check whether yours has cut-outs or ducts for brake cooling, a sensor or a washer line. These vary by specification.
  • Compare the material. The same position is made as hard plastic on one version and as a felted shell on another, and they use different fixings.

What to look for in the photographs

A Part number — Moulded into the inner face. It is often the only difference between two liners that look the same.
B Fixing holes — The holes, slots and rivet points around the edge. Count them and compare the spacing with your own liner.
C Cut-outs and ducts — Any opening for brake cooling, a sensor or a washer line. These vary by specification and are part of the match.
D Edge condition — Look along the whole rim, particularly where the fixings pass through. This is where a liner tears out.
E Material — Hard plastic or a felted shell. They are not interchangeable and they take different fixings.
