FORD issued a recall on the F650 and F750 models

On certain vehicles, grease in the S-cam lubrication tube of the front and rear axle assemblies was omitted during vehicle assembly. If the S-cam is not lubricated, corrosion may develop over time, which may restrict release of the service brake at the affected wheel and may result in excessive brake temperatures and possibly longer stopping distances. Longer stopping distances could result in a crash causing property damage, personal injury or death. Correction: Dealers will add lubrication to the S-cam lubrication tube and will inspect the S-cam operations.
