Also changed front and rear differential fluid.
Front diff = 1.5 quarts
Rear diff = 0.85 quarts
75w90
The rear had a bit of gunky mix in there compared to the front - expected due to temp differences etc.
You can see the picture of the rear diff drain plug the line of gunk around it and also the picture under it of the mix that actually came out - muddy
I include pictures for the front differential to show you guys where the fill, check and drain plugs are located (Front Diff Fill is located on the passenger side)
Definitely worth to change it! I used Amsoil as does my brother on his Legacy
