All are equipped with dual rear wheels and front hub extenders.
These front hub extenders are improperly torqued into place.
If you own one of 17,616 affected 2021 Ford F-Series Super Duty, specifically an F-350, F-450, F-550, or F-600 with dual rear wheels and front hub extenders, it’s possible you will have noticed vibrations and noises while driving. If this is the case, there’s a very strong chance your Super Duty is part of this recall.
Ford recommends that owners not drive their F-Series trucks as the front wheel assembly will detach from the front axle. So far, two owners have reported that a front-wheel has detached from their truck while in motion. Thankfully, no accidents or injuries occurred following the incident.
Ford, as reported by Autoblog, has said about the recall: “Due to a supplier process error, the automated torque station for tightening and verifying the torque of the nuts joining the front wheel hub extender to the rotor may have been bypassed at the supplier axle assembly facility. The nuts connecting the front wheel hub extender to the rotor may not have been tightened to specification.”
Ford has sent out recall notices already. The fix involves the dealer inspecting and tightening the bolts to the correct torque specification if required.
