Rear Diff CV Seals

Recently changed a real differential cv seal on my 06 mounty. I was in a hurry and bought the seal from Autozone. 2 weeks later the seal is weeping just a little bit around the axle (which is newish). So I went to my dealer today and bought Motorcraft seals. They are significantly heftier. Much thicker and heavier and over all, more stout.

Has anyone had any experience with this? Did I get the wrong seal from Autozone? I can’t imagine the aftermarket one can be that much less in terms of quality and still be considered oem.
