In today's market it is cheaper to replace it with a rebuilt unit with a warranty than to rebuild yours and not have any warranty. So I would not even attempt to do it.

However if your still dead set on doing this...... You will have to disassemble your alt, check the stator for shorts or opens, replace if any are found, check the fields for shorts or opens and again replace if any are found, with out question replace all bearings and voltage regulator then the brush sets, then after you get all put back together have it tested to make sure it works before putting it back on.

If you need to ask how to rebuild an alternator, you may not have the knowledge to do it correctly and I would take it to a qualified rebuild shop or buy a rebuilt unit. Not trying to be offensive here.....

As tennisshoes said, don't bother. If you can even find the parts, it will be more cost effective to replace it with a remanufactured alternator. I work for NAPA and we can still get parts (with some luck) for alternators on older stuff. Say '50s & '60s but not on something as new as yours. It's just not something that's done anymore.
