thanks guys - im no expert when it comes to this - personally i dont see how manual hubs would hurt anything at all except for having no tod - as far as the transfer case goes if they can find or make the seals it should be good as new so i dont need a new transfer case but i have a set of seals ordered from japan anyways just in case (could be 8 weeks) maybe they can help someone in the future if i dont end up needing them
