This thrust washer:
• Ensures proper wheel bearing preload by providing the correct support surface.
• Distributes torque evenly when adjusting the bearing retaining nut.
• Helps maintain smooth hub rotation and reduces bearing wear.
• Preserves correct wheel alignment and prevents unwanted play in the front hub.

A worn thrust washer can no longer hold the correct bearing preload, which can lead to wheel play, noise, or premature bearing wear. Grooves, distortion, or surface damage also affect how evenly the bearing nut tightens, reducing hub stability. Replacing the washer ensures proper bearing adjustment, smooth rotation, and safe, reliable front-wheel performance.

Replace this washer if:
•  You are installing new front wheel bearings
•  The existing washer shows scoring, grooves, or wear marks
•  The front wheel exhibits play or noise
•  You are doing a front hub rebuild or restoration
•  Any deformation is visible on the washer face
