This year is 20 since I posted that. I haven't owned a Subaru for a few years now, for various and sundry reasons, but that doesn't mean I don't look at the nice Forester XT, BC Legacy, BP Legacy GT, WRX STI, or even the odd Crosstrek.I went in to the Q-Lube that I used to work at today. I changed the fluids in the rear differential, final drive and auto transmission. For a vehicle with nearly 90k miles, I don't think any of them have ever been changed. If they had ever been drained, it was some time ago, and they sure did need it again. There are perks with knowing the manager at a lube shop, you get great discounts (read: free) services that would cost you a lot otherwise. If you haven't changed the fluids in your boxes recently, do it, nothing is more important for the reliable operation of your AWD system than to keep clean fluid in them.
It started as something for me, and turned in to something for you. I'm good with that.
Thanks to Josh, all of the moderators, and the excellent community we've made here.
