i need help on how to replace the pin in my 1989 Chevy beretta gt please help me
Buy a new hinge from the dealership it should cost about 20 - 25 dollars. you will get the upper and lower hinge for either the driver or passenger door. there are only four bolts holding each hinge on . use a marker to mark where the old hinge was then take off the old one. you can do this with the door being ajar but i am told that it is easier with the front fender off. it will probablly take two people to do this. I would also suggest that you purchase the haynes manual for the car they are very useful.

Replace the hinge pins and bushings.

free and you can do it yourself!!!! get a socket or 2x4 and open the door, place it in the hinge and pull the door closed on it to bend the hinges back, you'll have to experiment to get it right.
There is a spring on the fuel door hinge that keeps the fuel door closed. I hope this info helps.
I found an excellent web page that walks you through this step by step: http://bodyshopzone.com/archives/mechanical/door/hinge/pin_replace_1.html
The old door hinge pins have to be cut out with a torch on a 1989 F-150. Then, new hinge pins can be welded into place. This part might be available at an automotive salvage yard for a fraction of the cost of new hinges.
