How do you change a starter motor in a ford E350?

You have to take off the air intake cover and wires from a sensor located in a elbow like joint for air intake assembly, plus 2 bolts at the top . Unscrew the clamps. Now there are 2 ground connectors/bolts on the front of the starter, remove those too. starter are hanged with 2 bolts, one 18mm at the top and the bottom one is 15mm remove those and free it comes.
