grr...starting problems..any ideas?

[Rev]

I bought an AutoZone Duralast starters for the life time warranty. I've had 4 or 5 in the last 7-8 years. My starters always crank slower when the car is hot, but a good starter will always start the car within a few seconds. The first sign that I get that the starter is going south is really slow hot cranking. I usually wait till the car will barely start hot and then take it back for testing. It's always been "yes, the starter is bad". Then they have to give me a new one because I've learned to keep a file with all old sales slips. As I said, I think I'm on #5 now. It seems each starter motor lasts a year or so with not too many miles. This has been my experience with rebuilt starters. Alternators for me are about the same. They have to give me a new one every year or so. I could buy a new OEM unit from Ford for 4 or 5 times the price, but I'm a cheapskate at heart I guess.
