Ford is recalling 37 model year 2026 F-150 pickups because some of their rear axles were built with the wrong tail bearing. Ford told federal regulators that a bearing that is too small for the job can seize, locking a rear wheel or letting the driveshaft separate. The company filed the paperwork with NHTSA on Sept. 9, 2026, and owner letters were scheduled to start mailing on Sept. 21.

The trucks were built over two days, May 27 and 28, 2026.
An 8.8-inch bearing where a 9.75-inch part belongs
Ford’s defect report, filed as NHTSA recall 26V576 and Ford number 26S63, says some max tow package rear axles went together with 8.8-inch tail bearings instead of the specified 9.75-inch bearing, part number ML3Z-4621-A. According to the filing, the smaller bearing is not rated for max tow use and lacks adequate material hardness, so it can seize after extended service. All 37 trucks are presumed to carry the fault. Of 38 vehicles shipped before a stop-ship order, 37 were built for the United States or its territories.
Ford’s account of the timeline is unusually specific. Plant personnel noticed the wrong bearings on May 26, 2026, and shipments were confirmed on May 28. The company issued a stop-ship on June 3, took the matter to its Critical Concern Review Group on June 11, and approved the field action on Sept. 1, more than three months after the line stopped.
What a seized bearing does to the truck
The risk Ford described is loss of control or loss of drive power. If the bearing seizes, a rear wheel can lock up. If the failure progresses, the driveshaft can separate from the axle, and a truck parked without the parking brake applied could then move on its own. Ford said owners might hear increasing noise as the bearing deteriorates. Autoguide, in its report on the filing, summarized the hazards the same way and added that dealers will inspect the rear axle assembly before replacing the bearing.
Ford stated in the filing that it is not aware of any reports of accidents or injuries tied to this concern, and the report mentions no warranty claims. Because the trucks are new, the exposure so far is measured in a few weeks of ownership rather than years of towing. Whether any of the 37 had been sold and driven before the stop-ship and recall decision is not stated in the report.
Max tow packages exist for trucks that haul heavy trailers, and the filing ties the risk to that duty. The 8.8-inch part is not rated for max tow use, so a truck pulling a loaded trailer would put the most strain on the weaker bearing. Ford said the condition could show up as increasing noise as the problem worsens, and that a vehicle in park could move unintentionally if the parking brake is not applied after the driveshaft separates. Autoguide reported the NHTSA campaign number as 26V576000 and noted that affected VINs would be searchable on the agency’s site.
Remedy, advisories and how to check
Dealers will replace the 8.8-inch tail bearing with the correct 9.75-inch part at no charge. The consumer advisory in Ford’s filing is Do Not Drive and Park Outside, a stronger instruction than most recalls carry. Dealer notification was set for Sept. 14, 2026, the same day the affected vehicle identification numbers were due to become searchable, and the recall is phased. CarComplaints reported that owners should cite recall number 26S63 when they call Ford at 866-436-7332.
Ford says the trucks were not built in VIN order, so eligibility cannot be inferred from a serial number range. Owners and dealers can run the VIN through NHTSA’s recall search or ask a Ford dealer to check the company’s OASIS database.
The recall is also notable for how little of the fleet it touches. The affected trucks left the plant during a two-day window and were stopped before wider shipment, which is why the count is 37 rather than the thousands that usually attach to an F-150 axle campaign. Ford’s phased schedule has owner letters going out between Sept. 21 and Sept. 26, 2026, and the VIN lookup was due to go live on Sept. 14, a week before the first letters.
One of several Ford campaigns that month
The bearing recall is the smallest of a crowded set. Work Truck’s October recall roundup lists 26S66, which covers 17 model year 2026 F-150s with under-tightened stabilizer rod fasteners, and 26S69, a much larger campaign covering 223,472 F-150s from 2023 through 2027 whose fuel tank may be poorly secured. Both used the same September mailing window as the bearing campaign.
The number that stands out in the filing is 38: one truck shipped with the wrong bearing but was not built for the United States, and the report does not say where it went or what became of it.
