Re: Thought I had a beauty ..... BUT
If I'm reading you correctly, it could be as simple as someone installing one leaf spring backwards... the locator pin isn't centered on the spring, and if the springs get bolted them up wrong (one correct, one backwards), it will cause a crooked axle and the visible symptoms you're describing.
