Creaking Noise While Backing Up

[GasHog369]

for the last 2 weeks ive been noticing im getting a creaking noise when i back up into my driveway... If i pull up to my driveway and turn left to put my truck on a angle to back in, i crank the wheels to the right and start backing up and i hear the noise. Now it dosent happen everytime, id say 7 out of 10... the noise sounds like its coming from the pass front wheel to the cab... I still got another year or so of the factory warranty so im not worried there. But want to get a heads up of what it could be before i take it in...
