no weird noises. runs like every other 7.3 ive heard. dad's fleet of 94-97 7.3's all had to have the proportioning valve replaced...i'm going to bleed them when i do the rear shackle mounts and see if it helpstrust me, when/if that vacuum pump lets loose (if that is it), you'll wish you'd replaced it sooner. Luckily mine crapped out in the driveway, you just need a puller to get the pulley off. When that thing let loose I couldn't stop it, lol and it was just rolling down the driveway
do you hear any weird chirping noise from that area of the pump?
