problem with starter on 93 ranger

my starter went bad the other day on my 93 ranger. i had to roll start it. after i got it home it still didnt work. i tapped the starter with a hammer and now it starts. is the starter still bad or is it fixed now.

heheh, the hammer technique has never worked for me, maybe i'm hitting too hard. if it were me, i would replace it before it causes any more problems. the last thing you want is to be doing any more push starting. unless you need the excersize and appreciate the minor workout it gives you.
