I went through rebuilt starters very quickly on a Cleveland engine.
Finally, I gave up and took one to a shop that rebuilds starters and alternators...never had a problem again.
The moral of the story is "Don't go cheap, go good". I suspect the same result could have been achieved had I just bought a NEW starter from my Ford dealer...the rebuilt stuff could not stand the heat in that small engine compartment (it was a 1971 Mercury Comet, the same car as a Ford Maverick), but a quality rebuild returned the starter to as-new condition and the problems disappeared.
Cheers, and good luck!
