2005 f250 slow weak crank

The truck in question has a 6spd manual if that helps. i noticed it was cranking slower than usual. i checked the batt cables an they were a little dirty and corroded not the worst ive seen but still. so i got some terminal cleaner and took the cables off and cleaned them. this made a small improvement but the problem persisted. also the engine started reving up and down at idle just a little bit but enough to notice. it would only do it some of the time but started doing it constantly and it continued to crank slow. yesterday morning was out and when i started the truck it cranked much slower than usual but did start. it drove fine and i went home went to start it later and it barely turns over cranks extremely slow. i put brand new batts i got in it and the problem remains i checked all connections and they are tight i also noticed the other accessories work just fine and i can hear the vacuum pump and the clicking that the vehicle makes before you start it. although when you crank it the voltage drops dramaticly. i dont trust the factory gauges but i think the voltage dropping pretty good. ive heard this is a known issue with these engines and the problem ranging from fcim the icpr even a siezing ac comp or of course the starter. has anyone had same prob? or know test procidures? this truck is for my work and my primary vehicle would like to get it up an helping me make money. also please excuse spelling and grammar as i am posting from my not so smart phone. thanks in advance for any help you guys know yours strokes so i came here

99% it's your starter, had this exact thing happen to me a week ago. Had batteries and alternator tested, all tested good. Starter was dragging bad.
