This bush is used in the front wiper arm / linkage mounting assembly on selected classic Porsche models.

What This Part Does / Functions
•  Cushions and supports the front wiper arm shaft / spindle
•  Helps locate the wiper arm assembly correctly
•  Reduces vibration and movement in the wiper mechanism
•  Supports smooth and stable windscreen wiper operation
•  Helps prevent rattling or looseness around the wiper arm mount
•  Replaces a worn, cracked, hardened or missing original rubber bush
•  Provides correct OE Porsche rubber profile and fitment
•  Supports proper reassembly of the front wiper linkage / arm system.

Why Replace This Part?
The wiper arm rubber bush is exposed to water, sunlight, temperature changes, age and movement from the wiper mechanism. Over time, the rubber can harden, crack, shrink or perish. A worn bush may allow excess play in the wiper spindle or arm mount, causing poor wiper movement, vibration, rattling or incorrect seating of the wiper assembly. Replacing it with a Genuine Porsche OE wiper arm assembly rubber bush helps restore correct fitment and smooth operation of the front windscreen wiper system.

Common Symptoms of a Worn Wiper Arm Bush
•   Loose or wobbly front wiper arm assembly
•   Excess movement at the wiper shaft / spindle
•   Rattling or vibration during wiper operation
•   Poor or uneven wiper sweep
•   Water ingress or looseness around the wiper spindle area
•   Cracked, hardened or perished rubber
•   Missing bush after previous wiper linkage work
•   Wiper arm not seating correctly at the mounting point.

When to Replace This Part
•   When rebuilding the front wiper arm or linkage assembly
•   If the original bush is cracked, hardened, perished or missing
•   If the wiper arm shaft has excessive play
•   During windscreen wiper system restoration
•    When replacing wiper arms, linkage parts or spindle hardware
•   If wiper operation is noisy, loose or unstable
•   During classic Porsche bodywork or scuttle area restoration.

Where It Fits on the Car
This rubber bush fits in the front windscreen wiper arm / wiper shaft assembly. It supports the wiper spindle / arm mounting area and forms part of the wiper linkage hardware at the front scuttle / cowl area. Correct installation helps ensure the wiper arm assembly is supported and aligned properly.
