1991 Ford E-150 Problems
The front end may make a rattle noise over bumps. There may be handling issues, and play in the front wheels on inspection. If there is up and down movement on the front wheels while the lower control arms are being supported, inspect the upper and lower ball joints for excessive play. These are prone to failure from moisture entry and lack of lubrication. The ball joints should be replaced as needed.
Electrolysis can cause repeated failures of the heater core and radiator. The diagnosing technician should check for voltage present in the coolant, with the battery disconnected, because electrical current in the coolant causes electrolysis. Corroded or deteriorated parts should be replaced, and the coolant should be flushed. Ground straps can be added to help prevent future corrosion of components.
In some cases with higher mileages, the Check Engine Light may come on due to insufficient Exhaust Gas Recirculation system (EGR) flow. For EGR flow concerns, the EGR valve is usually recommended for replacement and the intake manifold is removed to clean the EGR passages in the engine, which have clogged with carbon over time.
