You will have to check everything on your steering and front suspension to figure out what is going on with your wandering. DBGIL is right about the steering coupler, also you need to check your tie rod ends, steering box play, ball joints etc. You didn't say if your truck has a lift or is 4wd this info will help the site help you.
As far as the steering wheel goes, I think before you go ordering new parts ($$$$) see if you can get a Factory Service Manual or borrow one or maybe someone on the list can email you the right pages concerning your steering. I would pull the wheel off and go through the column making sure all the parts are there (I would bet they are) and look for loose bolts or screws. The tilt wheels have a habit of working loose over the years. Not a big deal you just retighten four bolts with a bit of blue locktite on them and the steering is fixed. You could have a broken part inside the column, or the ball bearing races/retainers are broken.
In short get a auto parts store to loan you a steering wheel puller and dig into it. Let us know more facts about your truck, 4 wheel or 2wheel drive, lifted or stock suspension, stock size tires or wider/taller aftermarket ones.
Good luck
