Alternator, replace it before it leaves you stranded as they seem to just fail all at once. With no voltage gauge to moniter them this would be a good part to just replace anywear after X amount of miles. I'm thinking 75K maybe sooner ?
Another one might be to remove and clean turn signal lenses, etc. as they can get pretty funky inside and not reflect light as well as they should. Their gaskets and bulbs could be replaced too at this time. Bulbs if their bad or not, and gaskets if available ?. This could be done at 5 years? or as needed.
And the CV joints is a good one. And maybe replace the rubber boots at the same time??? ( now I'm thinking about my CV joints )
Another good maintenance practice IMO is to just get the car up on a rack at least every year and just inspect everything by eye.
Good thread
