I coincidentally ran through a mud hole and all my electronics started flickering, AC turned off and on, speedometer and tach stopped working until it dried out, then the battery wouldn't hold a charge. needless to say alternator had taken a shat, so I changed out my factory alternator. easy job. 2 hours top for a job like that and never touching under the hood of a car.

I heard somewhere that every 150k miles is a nice time to think about change.
I also have same dilemma, because this event is the only one that stopped GX on round in past 15 years..
I got in my 2007 with 130k on it the other night and heard a loud whining noise. At first I thought the air pump, then power steering pump. Got under it and was obvious what/where was causing the noise. Swapped out, noise gone. I've read alternators have a 7 year life.
