You can't. The entire hinge must be replaced.

Completely FALSE! The pins can be replaced and are currently available for ~$6 from Advanced Auto Parts stores (Motormite #38419). First, the detent spring must be removed. Support the door either on a jack or some stands of the proper height. Remove the retention washer from the top of the pin. Then push the pin out of the hinge. Replace the bushings with those supplied in the replacement pin kit and push the new pin up into place the same way that the old one came out (make sure to lubricate the pin properly with some heavy grease). Install the retention washer and reinstall the spring (which is easier said than done).

Taking the spring out was hard and I've never been able to replace the old one. I here there is a special tool to do this but it is not that important to me. Be careful removing the old spring.

I have replaced the door hinge pins and bushings many time on my 99 Chevy blazer. You can buy the kit at autozone or most auto parts stores. My friend owns an autobody shop so he has the spring depresser tool to remove the detent spring. You may be able to buy the tool in an auto parts store or maybe even rent one. But if you can remove that spring just follow the directions above! Good luck!

The spring compressor tool is very cheap and runs about $10 at Advance or Auto Zone. Spend the little extra money to do the job right. Without it the door opens way too easily and is not held open. The best write up can be found here:

My advice based on experience is to replace the entire hinge assembly.

I wouldn't mess with the pin, the door hinge can have a washer/spacer placed under it and bring the door back in alighnment. I have new hinge pins available if you really want to change them.
