Service bulletin SSM 48821

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Ford has received reports of toe link failures after the installation of non-OEM cross-axial ball joints in the rear wheel knuckle, and if service of the rear wheel knuckle and bushing assembly is required, the recommended repair is to replace the affected 5B758/9 assembly.
