HELP!!!!!!!!!!!!!!I have gone through at least 30 pairs of cen front and rear stock replacement diff cups in the last month and i just broke my last set[:@]. I e-mailed cen and all they said was somethin else must be out of sink because the stock cups should not break that easy.Does anyone make a stronger allum or titainium set[>:]?what else could be wrong, i know i ain't the only one who has this problem[&:]. is there a cheaper and more permanent solution than buying a $5 set of diff cups every 2 days?HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!
