Any recommendations for an alternator replacement on my 2011 legacy. It has 170,000 miles on it now. I have rebuilt the heads (due to over heating caused by internally leaking head gasket that the dealership couldn't find). This was done as well as all the timing pulleys and belts at 135,000. I'm getting ready for a 2,000 mile trip and thought I should be proactive and replace the alternator to avoid breakdowns. I used to rebuild them myself in my younger years, but I guess I'm getting lazy and a new alternator would have all new parts. Any recommendations would be appreciated, thanks
