1990 Ford F-150 Problems
RepairPal has identified the most common problems with the 1990 Ford F-150 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing differential clutch kit. An updated differential clutch kit available.
The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.
The Ford F-150, with the optional 5.0L/302ci V8, may develop misfires, rough running, and loss of power, accompanied by the check engine light illuminating.
Replacement of the ignition wires, and securing them away from the exhaust manifold is necessary to remedy the rough running conditions.
The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.
Tubes for the EGR system (exhaust gas recirculation) can break, causing an exhaust leak and noise under the hood.
If there is a vibration or noise at highway speed, it could be from the frontdrive shaft and may require replacement of the double cardan joint. A double cardan joint is a type of driveshaft joint that uses two universal joints.
