So if I just give the pinion but a little more preload the howling night go away? Okay I just was starting to thinking I'm going to have to take it all apart or send it back. Thank you for the info. My buddy said they're is also a chance the howling will go away once things are worn in?

Just up and grab the yoke ! Then see if the yoke moves back in fourth or side to side ! If the pinion is lose , it will cause all these things that you are being told ! If the pinion is loose that’s going to change the backlash settings ! Because the pinion is moving back and fourth on the ring gear ! If your pinion has a crush sleeve you probably will be able to tighten the nut and crush the sleeve more ! If it has shims for the pre load you will have to reshim for your pinion bearing pre load ! But do check the pinion nut for tightness also !
