The easy place to start is checking tire pressure and rotating tires front to back and see if it changes.
It wouldn't hurt to put the truck and stands and check for play in the wheel bearings, steering/suspension linkages and bushings, etc. Again, easiest to take it to your tire shop to rotate the tires and ask them to check everything for looseness or play while it is on the rack if you don't want to do it yourself. If they claim to find a problem, ask them to show you before agreeing to do any repairs.
