I noticed a day or two ago I was getting a vibrating noise out of what seems to be the front of the truck all of a sudden. While driving it would come and go, seems like when I'm coming to a stop I can hear/feel it more so. Any ideas? I'll jack it up and spin the wheels and look around to see if I spot anything. I know I need a new driveshaft center support and slip joint boot but this is a new sound/vibration. Installed new shocks and a steering damper probably 6 months ago, and new brakes and rotors before that.

 

I chased a vibration on mine for several weeks.it would come and got making finding it harder.

I'm the end it turned out to be my cab mounts ,the center mounts had completely disintegrated allowing some metal to metal contact.
