Windscreen Wiper Support Bush, RHD.
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.
Fits:
Diagram Ref No 23
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.
What This Product Does:
The Wiper Support Bush locates and supports the wiper spindle within its mounting or bearing assembly.
Its main functions are to:
- Support the wiper spindle.
- Maintain correct spindle alignment.
- Reduce excessive movement at the wiper mounting point.
- Help the spindle rotate smoothly.
- Reduce vibration and rattling.
- Support consistent wiper-arm movement.
- Maintain correct positioning of the wiper mechanism.
- Replace a worn, damaged or missing original bush.
- Restore the factory mounting arrangement.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Wiper spindle feeling loose.
- Wiper arm wobbling at its mounting point.
- Excessive sideways spindle movement.
- Rattling during wiper operation.
- Clicking or knocking.
- Irregular wiper sweep.
- Wiper arm moving inconsistently.
- Excess vibration.
- Bush visibly worn or distorted.
- Bush cracked or missing.
- Increased movement around the spindle.
- Wiper linkage no longer sitting correctly.
Why Replacement Matters:
Replacing a worn Wiper Support Bush helps restore:
- Correct spindle support.
- Reduced wiper-arm play.
- Smoother wiper movement.
- Improved linkage alignment.
- Reduced rattling and vibration.
- More consistent wiping.
- Factory-style component fitment.
- Long-term wiper-mechanism reliability.

The windscreen washer pump draws washer fluid from the reservoir and pushes it through the washer hoses to the spray jets. A working pump is essential for cleaning the windscreen and maintaining safe visibility in wet, dirty, or dusty driving conditions.
Functions
• Replaces the windscreen washer pump
• Pumps washer fluid from the reservoir to the washer jets
• Supports clear windscreen visibility
• Helps restore correct washer spray operation
• Suitable for washer system repair or restoration
• Replaces failed, weak, noisy, leaking, or seized washer pumps
• OE Match replacement for Porsche washer system service.
Why Replace This Part?
Windscreen washer pumps can fail due to age, internal wear, blocked washer fluid, electrical faults, corrosion, freezing, or dry running. A faulty pump may stop spraying fluid, produce weak washer jet pressure, leak from the pump body, or make noise without delivering fluid. Replacing the pump helps restore proper washer system performance and road-safe visibility.
When to Replace This Part
• Washer jets do not spray fluid
• Washer fluid flow is weak or intermittent
• The pump runs but no fluid reaches the windscreen
• The pump is noisy, seized, leaking, or inoperative
• Washer system faults are being investigated
• The washer reservoir or hoses are being serviced
• The vehicle is undergoing Porsche 911, 928, or 964 restoration.
Where it fits on the car
This washer pump fits within the windscreen washer system, usually at or near the washer fluid reservoir. It supplies washer fluid to the windscreen washer jets according to the factory washer system layout.
