Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 12 October 1977.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
Vehicle description: heavy trucks equipped with FF931 front axles and motorwheel aluminum front hubs.system: wheels; aluminum hubs.consequences of defect: when hub failure occurs, the separated hub is retainedon the axle spindle by the wheel bearing adjusting nuts. Continued vehicleoperation after a hub separation can result in 1) brake assembly lockup andconsequent loss of vehicle control, 2) excessive heat generation resulting fromthe brake line touching the brake drum which will cause a tire blowout and 3)PROGRESSIVE damage to the hub which would allow the hub, wheel, and tire tobecome disengaged from the vehicle.note: initial hub separation may be accompanied by a distinct sound at themoment of separation, along with thumping or wheel wobble.

This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
