I think the issue was if it had to much moly, not the moly itself. I am guessing ford wanted a 1 size fits all grease so they added enough moly to work as a decent chassis grease but not so much it would damage or impair wheel bearings. Valvoline synpower grease has a little moly in it and many use that on wheel bearings, as have I, without issue.
I use different greases for wheel bearings than chassis now as I wanted a better chassis grease. My grease gun right now has Jet-Lube 202 grease while my bearing packer has some clearance Castrol syntec grease in it.
