September 16, 2017 — Ford is recalling 630 wheel hub bearing assemblies sold by Ford Component Sales to aftermarket parts resellers Timken and SKF.
The wheel hub bearing assemblies were shipped between March 6, 2017, and March 23, 2017, as replacements for certain 2011-2017 Ford Explorer front-wheel-drive SUVs. However, the assemblies aren't compatible for the rear wheel hubs of front-wheel-drive Explorers.
The hubs of drive axles rely on halfshaft retaining nuts to secure the bearings while the non-drive axle hubs have self-retention features, so missing halfshaft retaining nuts will cause loose hubs, and dangerous hubs. A driver will likely hear a grinding or rubbing noise from the brake rotor noise, or experience wheel wobbling while driving. Z
