Starter squeal

[Ray Sta.Juana]

Ok, I've had the squeal since April of this year and I've been just dealing
with it but it's getting ridiculous.  It used to be only a split second but
now it's more like  3-5 seconds.  Sometimes the car has a hard time starting
too but that's rarely.  Can this problem be remedied by NOT replacing the
starter? As in lubing it or somehow making some adjustments? If not then is
it ok to get a remanufactured starter from Autozone or should I get OEM?
Does it matter that much? TIA
