After posting my question earlier, it would seem that I had a save just after curing Kodlak, where Vilkas and Farkas were both still in Ysgrammor's Tomb. When talking to Farkas in the tomb, he has a misc quest available so in taking this quest I was then able to take Farkas' Purity quest, then after a misc quest off of Vilkas I was able to complete his purity quest.

If this situation is not unique, I hope it may help people solve their purity quest bugs.
