Alternator vs. Voltage Regulator

140K miles is about right for the brushes. The voltage regulator and brushes come as one unit that is removed from the back of the alternator with a screw driver. Make sure that you disconnect the positive battery cable before you replace the VR. Replacement should take about 10-15 minutes.

The original Bosch alternators are very robust. It is not unusual for them to last 250,000 miles (with one or two VR/brush pack replacements). I would NOT replace the alternator in your car unless it needs it because even the remanufactured Bosch units are relative junk. You are lucky if a reman lasts 5 years.
