that is NOT true. i dont know where the thread is on pirate, but if you PM him over on pirate i am 99% sure that he will warranty them even if you do dont have the hub gears.
that being said it is a good idea to get the hub gears because if yours let go they are more than likely going to ruin your birf.
Call Terra at Toyota Superaxles and she'll explain the warranty deal. if it has to do with the bearings or inner axle it's warrantee'd without the hubgears, but if it has to do with the endbell portion of the birfield that slides into the spindle assosciating with the hub gear, then it's not unless you have his hub gears, but if the gear is the cause of the birf exploding then it's not warrantee'd without the gears...it's complex to clarify, but she'll explain it
