Well it appears the Configuration for adding fields for vBulletin ranks doesn't allow to add vB Ranks nor display the Rank images. I don't know why it won't allow me the option to link or add vBulletin User Ranks as the [Add Profile Fields] don't have it in the list from Configuration >> User Profile Fields [Manage] options.

Note: NOT ClanMembers based ranks, but vBulletin User based Ranks.

You can only show the clan members ranks, not the vBulletin ranks.
What you can do there, is hide xfire.
