Are all 2WD yota axle smaller in diameter than 4WD? Mine is not a 3 inch axle like I thought it was.... now my truck is all ripped apart and the parts won't fit.... any ideas?
Yes. One exception might be the Prerunner Tacomas, however I am not 100% certain on that. Get a 4WD rear axle from a junkyard, the Marlin or the Pirate classifieds. They are cheap and plentiful.
