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.

1990 Ford F-150 RecallsFord Extends Warranty Coverage for 1990-1993 F150-F350 Trucks Fuel Pump/Sender Assembly
Ford has extended the warranty coverage of the fuel pump and sending unit assembly in 1990-1993 F150, F250, and F350 trucks. In some trucks, the check valve may become damaged inside the fuel pump unit. This can cause fuel to travel from one tank to the other, creating an overflow condition. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will repair the fuel pump and sending unit for up to 12 years or 150,000 miles from the original warranty start date.
Ford has recalled 1990-1993 F150, F250, and F350 trucks due to a faulty fuel pressure regulator and malfunctioning fuel pump check valves. Fuel may transfer from one tank to the second tank, causing a possible overflow condition and fire hazard. Dealers will replace the fuel pressure regulator and install redundant check valves.
