Is there an actual way to check the level? My mom's 12 Edge has developed what appears to be an axle seal leak, so I will want to be sure the level is correct once I get the seal changed. I do most all of my own work, and have for a long time. I am trained, but left the field. It is out of warranty already before that suggestion comes out. 125,000 miles on it already. Been a few little things that went during warranty, and one big one. The turbo gave out with about 4-6000 left in warranty, the power steering line was leaking at about 40,000, then one other thing I'm not remembering right now.
