WASHER - WHEEL AXLE (Nissan NIAL5100399)

A worn wheel axle washer can allow axial play that leads to uneven tire wear and potential hub damage. This aftermarket replacement part references Nissan catalog number NIAL5100399. The washer functions as a load-spreading spacer between the axle shoulder and the wheel hub. Its plain mechanical role is to maintain correct bearing preload by providing a precise thickness interface. A common failure consequence is that a collapsed or missing washer causes excessive end-play, which accelerates bearing failure. The item ships at approximately 0.041 pounds. Verify the serial number or application, then call (562) 693-7748.
