The Genuine Porsche Wiper Support Bush 91162875301 is a replacement support bush used within the wiper spindle and bearing arrangement on selected classic Porsche 911 and 930 models.

The bush provides a correctly sized support surface around the wiper spindle, helping locate the rotating wiper shaft securely while allowing the mechanism to operate smoothly.

Although small, the support bush plays an important role in maintaining correct wiper-spindle alignment.

Over time, the original bush can wear, harden, deform or become damaged. Excessive wear may allow the wiper spindle to move within its mounting point, resulting in looseness, rattling, irregular wiper movement or poor alignment.

Replacing a worn support bush helps restore correct spindle support and smooth, stable wiper operation.
