Thrust washer for wheel bearing front. Porsche 911 / 912 / 914 1963-73  ❭  90134166301

Thrust washer for wheel bearing.
This OE-match front wheel bearing thrust washer (16 mm) is used on the outer front wheel bearing of early Porsche models, sitting between the outer bearing and the spindle nut within the front hub assembly. It provides the correct friction surface and distributes load evenly when adjusting wheel-bearing preload—essential for smooth hub rotation, proper alignment, and long bearing life.
Sold individually, two required per car.

Fits:
Porsche 911 2.0L - 2.7L 01/1963 - 07/1973
Porsche 912 1.6L 011965 - 02/1970
Porsche 914/6 2.0L 11/1969 - 12/1973

This thrust washer:
• Provides the correct support surface to set and maintain proper wheel-bearing preload.
• Distributes torque evenly when adjusting the bearing retaining nut.
• Helps ensure smooth, stable hub rotation while reducing bearing wear.
• Supports front wheel alignment accuracy and prevents unwanted hub play.

When the original washer becomes worn, grooved, or distorted, it can no longer maintain correct preload, leading to wheel play, noise, and accelerated bearing wear. Damaged washer faces also affect how evenly the nut tightens, reducing hub stability. Installing a fresh washer restores proper bearing adjustment, smooth rotation, and safe, reliable front-wheel performance.

Replace this washer if:
•  You are fitting new front wheel bearings
•  The existing washer shows scoring, grooves, or wear
•  The front wheel exhibits play or noise
•  You are performing a front hub rebuild or restoration
•  There is any visible deformation on the washer surface.
