i had a question, its similiar to this problem, i have a spool with 5.29's in the rear third and i just recently got this very BAD noise coming from my drive shaft, i've never had a problem with my drive shaft, looks like the joints on the short end of the shaft are rubbing??? it confused the crap out of me, i took it apart put it back together im thinking it has the be the cross slipping back and forth causing the joints to rub but its a very bad rub and is rubbing the metal off each other, i parked my truck cuz its un bearable listenin to that. i've never had problems with the angle of my drive shaft either, if i can get some help that would be great,
