I would get the front of the truck off the ground and start by checking the wheels for any play, up down side to side. If your tires are big you might take them off to get a look at your ball joints and struts. Check your steering rack for any play along with tie rods cv axles etc. I would fix the cv boot while there. Tires out of balance and warped rotors can be culprits too. You may need struts if you're still running stock and have hit any jumps lol
