when I drive down the road and let go of the steering wheel the truck will start to pull slightly to the right, even harder when in 4X4 mode. thought I had a bad caliper but everything seems to be ok with them, any ideas on what may be causing this, Thanks

So today I took it out again and noticed when I turn to the right I have a knocking sound in the front end, so im guessing a ball joint or a tie rod, any thoughts.
