Diagram Ref No 39

Mounted at the rear lid or body contact point, the rubber stop helps prevent direct metal-to-metal contact while supporting correct lid positioning. It also helps absorb vibration and minor movement when driving, reducing rattles and protecting surrounding bodywork and latch components from unnecessary impact.

As rubber components age, they can harden, crack, flatten or disappear altogether. Replacing a deteriorated rear lid stop is a simple but important way to restore correct closure, reduce unwanted noise and maintain proper panel positioning.

What This Product Does:
The rear lid rubber stop acts as a small cushioning and support point between the lid and surrounding body structure.

When the lid is closed, the stop compresses slightly to support the panel and absorb movement. This helps keep the lid stable while preventing hard contact between painted or metal components.

Its main functions include:

  • Cushioning the rear lid when it closes
  • Preventing direct metal-to-metal contact
  • Helping support correct rear lid positioning
  • Reducing movement and vibration while driving
  • Helping prevent rattles and knocking noises
  • Protecting surrounding paintwork and body panels
  • Reducing unnecessary load and movement at the latch
  • Helping maintain consistent panel gaps
  • Providing a more solid and refined closing action

Although it is a small component, the rubber stop contributes to both correct panel fit and everyday refinement.

Symptoms Of Wear Or Failure:
Rubber stops deteriorate naturally through age, heat, compression and exposure to moisture and environmental contaminants.

Common symptoms of a worn or failed rear lid rubber stop include:

  • Rubber becoming hard or brittle
  • Cracks or splits in the stop
  • Stop becoming flattened or permanently compressed
  • Pieces of rubber breaking away
  • Stop missing completely
  • Rear lid rattling over uneven roads
  • Knocking or tapping noises from the rear lid
  • Excessive movement when the lid is closed
  • Lid sitting slightly too low or unevenly
  • Poor or inconsistent panel gaps
  • Rear lid requiring adjustment to close correctly
  • Paint marks or contact points where the lid touches surrounding bodywork
  • Increased strain or movement at the latch
  • A harsher closing action than normal

Similar symptoms can also result from incorrect latch adjustment, worn hinges or other missing buffers, so the complete rear lid mounting and closure system should be inspected where necessary.

Why Replacement Matters:

  • A rear lid should remain securely supported when closed. If the rubber stop becomes compressed, hardened or missing, the panel can move more than intended.
  • This movement can create rattles and knocking noises and may allow the lid to contact surrounding bodywork. Over time, repeated contact can damage paintwork and create unnecessary wear around the lid, latch and mounting points.
  • A deteriorated stop can also affect how the rear lid sits when closed, potentially resulting in uneven panel gaps or poor alignment.
  • Replacing worn rubber stops helps restore the correct cushioning effect and supports the lid in its intended position. This can improve closure quality, reduce unwanted vibration and protect valuable surrounding bodywork.
  • For older Porsche models, replacing aged rubber buffers is also worthwhile during restoration, as decades-old rubber may appear intact while having become significantly hardened or compressed.
