Removing the starter from your Ford F250 may be necessary if the starter has failed or is not functioning as it should. Either the starter or the solenoid could be at fault. Once you have the assembly out of the truck, take it to an auto-parts store for testing. Most will bench-test it free and recommend a new starter or another part to solve the problem. Removing the starter in the driveway or garage yourself can save you a substantial repair bill and is a great job for the home mechanic.
Locate the negative battery cable on the battery terminal. Loosen the retaining bolt on the cable end with a wrench, lift the cable off the terminal and set it aside.
Position a jack under the front of the truck and raise it off the ground. Position a set of jack stands under the front suspension to support the truck.
Slide under the passenger's side of the truck and locate the starter motor at the rear of the engine, where it meets the transmission bell housing. Find the cover that protects the two terminals on the rear of the solenoid, grasp it and pull it straight off the terminals.
Remove the retaining nuts on the two terminals with a socket and ratchet, then slide the wires off the terminals and push them off to one side. Locate the ground eyelet and wire on the bottommost mounting stud of the starter.
Remove the ground retaining nut with a socket and ratchet, then slide the ground wire and eyelet off the stud. Remove the second nut from the stud and set it aside.
Move up the starter and find the two upper mounting bolts. Remove both bolts with a socket and ratchet and slide the starter out of the bell housing.
Carefully lower the starter out of the engine compartment. It is heavy, so do not lie under it as you pull it free from the engine and bell housing. Remove the starter assembly from under the truck.
