I have a 1971 F100 V8 360. My truck won't start and I hear a whining humming sound coming from underneath when I turn the key. I'm assuming its the starter, I don't believe it has ever been replaced. What kind of work am I expected to do? Is it pretty self explanatory? Any tips on replacing it?
What makes you think it's never been replaced ? 1971, that's a long time unless it's been in storage a lot. Some times you go though a couple before you get a good one now days. It could have been about 3 or 4 at least.

If the starter drive cannot engage the flywheel/flexplate ring gear because it has chipped teeth, all you'll hear is the starter spinning (making a humming sound).
Remove the starter, examine the ring gear teeth. Ring gear available by itself if a M/T, only available with the A/T's flexplate. Starter drive comes with the starter or available by itself.
If replacing the starter, there are two different FE types: 1958/62 is different than 1963/76.
There are two different FE M/T flywheel ring gears, two different A/T flexplates. 1958/64's have 153 teeth, 1965/76's have 184 teeth.
Some rain got in my starter while I was building my truck and it wouldn't do anything but click.. 2 bolts and a cable to pull it off then 1 screw to expose the starter drive then 2 long bolts to dissect the whole starter.. I brushed mine down with a wire brush and some wd40, put it back together and its stronger than ever! Don't be afraid to tear it apart! If a man put it together, you can figure it out too
most likely the starter is just not kicking the drive gear out to meet the flywheel (ring gear) problem is with the Bendix.
Bendix is a mis-nomer, as this refers the inertia starter used on 1958/62's. Bendix drive has a HUGE coil spring that has to be unwound by hand to get at the roll pin that retains it to the armature.
Rewinding this spring back into position by hand takes muscle.
And, how many people have replaced starters or starter drives only to discover to their horror, that the ring gear was chipped?
Left: 1963/76 FE starter / Right lower: 1958/62 FE Bendix inertia starter.
WD-40 on starter brushes? Horror.
The bolts from the starter to the mounting plate form the return ground path from the starter. Every 1/100-th of an ohm counts. That much resistance will drop a volt from the starter when the battery is pumping 100 amps.
Tighten starter bolts every chance you get.

I just reread my comment.. I don't see me saying i put wd40 on the starters brushes??
Then again I haven't blown one up 'yet'.......
Okay okay lol, I give up! Though I will admit I used it because I knew it would dissipate and dissapear so fast.. Seeing how a can cost more than a premium salad you may want to stick with ranch
