Starter drawing too much juice?

The starter in my car has always been mega loud but always functioned normally. Is it possible that a starter as it gets older could draw more and more current until even a healthy battery doesnt have enough juice to turn over the engine?
The battery in my car is only a few months old but in these cold cold cold mornings I'll only get maybe half a crank but once I jump it with another car in two minutes theres enough power to turn over the engine. Ive tested for excessive electrical draw with the car off and pulling the fuses one by one and didnt find anything drawing more amps than it should.

Yes, possible.

Do you know if these are brushed DC motors? I've never paid too much attention. Either way, a coil fault or brush wear could cause what you're describing. Doesn't mean that's the only possibility, but could cause what you're describing and there's no fuse or breaker on the feed to limit draw if I'm thinking correctly.

Okay thanks, second question, Ive read elsewhere that the starter needs to come out from the bottom meaning the car needs to go on jackstands. Please tell that it come out from the top!

Have you done a starter test? Most auto parts stores will do it for free.

You may be able to wiggle the starter out from the top if you unbolt the strut bar.
But I am fairly certain you would need to unbolt the starter from under the car.
The intake manifold and everything around it are in the way.

I have an update to this issue, for the past maybe two weeks the car has been starting fine in the mornings, except for today. It was about 3 degrees and it just didn't happen, I got a jump and drove a total of 15 miles before I shut it off. About 5 hours later my brother goes to use to get himself to work and its dead again. At about 8 he leaves work and SURPRISE its dead again. Once he got home I checked the cells to see if one was low and while all of them where full the one closest to the positive terminal had the rotten egg smell. The battery is a 47 size with 600 cc at 0 degrees. I still need to swap out the loud starter but the starter is really all I have to go on. Ive checked the car for a short when off and found nothing so Im really at a loss.

Small update with the car off there's about 200 miliamps draw. Is that a normal amount? How much voltage drop should I see when the engine is cranking?
