• Description:

  The W701731-S439 is a genuine Ford nut and washer assembly with a hex head and an integral washer, cataloged under the dominant name Nut And Washer Assembly - Hex. It appears in the front axle shaft mounting group alongside the axle shaft, retaining bracket, inner circlip, thrust washer and mounting stud, where it clamps the shaft or bracket hardware in place. Documented sample applications where this exact service number is cataloged include the Ford Explorer, Flex and Freestyle and the Lincoln MKS and MKT, along with the Mercury Montego and Sable; treat those as representative examples rather than a complete vehicle list, because Ford reuses one nut and washer assembly across many assemblies and model years and does not publish a single finite fitment chart for it. The captive washer spreads clamp load across the mounting surface so the nut holds securely without a separate loose washer; on an axle-shaft mounting that even clamp keeps the shaft and its bracket located against driveline loads. When it is loose, corroded or missing, the joint can lose clamp load and the component can shift, vibrate or knock. Because the suffix code denotes a specific thread size, washer diameter and finish, confirm fit for your exact vehicle by VIN before ordering rather than relying on the sample applications above.

• Notes: Included with compressor.
