I have a 2006 B9 Tribeca with 55,000 miles on it. Just last November I replaced the OEM battery with a new Duralast. Then during the winter we had a few days in the teens where the Subie didn't want to start nicely. Since installing new battery I'm still getting corrosion around positive terminal. I've used the 'ol baking soda mixture and wire brush to clean terminal. Its definitely taking longer to start than normal so I'm lead to believe starter is to blame. Also starters that are going out start to draw more current than they need so with that does anyone have any tips, pics, diagrams or suggestions for replacement. AutoZone has $186 + core charge for "new" starter.
