ok this is an odd question. i have a 5.3 with the kwipperformance bracket setup. it looks like everything lines up pretty close but when i start it the belt stays in the right groves in every pulley except for the balancer pulley which jumps one groove inward which shreds the belt after a few minutes. my question is could my balancer be backing off? can someone measure how far away from the cover it should be? or give me some reference to find out if its backing off?
