Ford Super Duty trucks may lose a front wheel

NHTSA campaign 21V390000 · Reported 2021-05-25 · Ford Motor Company

critical How serious is it? About this label

Extremely serious: a wheel can separate from the truck and cause a crash, and Ford instructs owners not to drive until the nuts have been checked.

⚠ NHTSA advises not driving this vehicle until it is repaired. See all such recalls.

What's wrong, in plain English

These trucks have dual rear wheels and extenders on the front wheel hubs. The extenders may not have been bolted on correctly, so a front wheel and its extender could come off while you are driving. Ford is telling owners not to drive these trucks until a dealer checks how tight the extender nuts are. The dealer will inspect and tighten them at no charge. Letters went out to owners in June 2021.

What you should do

1. Stop driving the truck and check your VIN at nhtsa.gov/recalls to confirm it is affected. 2. Call your Ford dealer or Ford at 1-866-436-7332 (recall 21S26) and ask how to get the truck in without driving it. 3. Have the dealer inspect and tighten the front wheel hub extender nuts, free of charge.
