Best Answer

Usually an alternator only needs bearings, brushes and possibly diodes and regulator. Most people rebuilding an alternator replace all of them. If you haven't rebuilt one or helped someone rebuild one it can be a little trickey. Some require that you solder the diode plate, others need very precise assembly. Often a rebuild kit costs more than a rebuilt alternator.
