Has anyone done their differential oil changes yet? If so do you have any words of wisdom on how to change the fluids and what gasket/crush washers will need to be replaced.
According to the service schedule the diff fluid is good for a lifetime unless it sees severe service then it is only good for 15k. Other Subaru’s recommended changing the diffs at 30k. Since I am past the 30k and plan to put lots if miles on my Ascent and gear oil is cheap I thought it would be good to change it out. I am hoping that someone is ahead of me on this one or read the service manual and can tell me how it’s done. Should be fairly straight forward but this is my first Subaru and I want to make sure that there are not any unusual steps to the procedure like on the CVT.At what mileage/under what conditions is it recommended to replace the differential oil?
My next concern is the 30k service to inspect the CVT and differential oil. Honestly I don’t trust a dealer to do anything more than look at it and call it good, which I really don’t feel like paying for, but I don’t know anything about doing that part of the service myself...
1.3qt and 0.8qt front and rear, respectively. Here’s what the manual says about the type of oil to use:I'll be doing both diff fluid changes myself as well in the near future. How much replacement fluid is needed for each diff? I normally use Mobile 1 or Royal Purple - does that work well for Subarus (this is my first Subaru).
