we believe it was just a manufacture defect in the steel the gears where made of.. currently i pulled the front gears and am driving it to work and back only. im trying to decide to fix it or to do a sas... if i had a buyer for the 12 rize i would do a sas.. but not to many people want or have the coin for a 12 rize kit... i'll take some pics when i take it apart but im gonna wait till i am fixing it and ill have lots of pics for you
