Truck: 2001.5 2500 4x4 90000 miles 285/75R16 tires

not too long ago I started noticing that at speed (above 30 mph), the truck would make pull to one side all of the sudden...usually while in a small turn on the hwy.

I did notice there was movement in the ball joint of the track bar while turning the steering wheel to the right. So the truck has a new track bar and I am still having the sudden pull.

the ball joints were replaced about 15k miles ago and the new track bar is the better spicer track bar.

. I plan on putting the front end on jacks this weekend and push/pull on every single component to see if there is any play.

any other suggestions what to look for?

I am assuming you mean the truck is pulling to the right or left as you drive straight down the road, often overlooked is the tires being underinflated, will cause a pull to one side. Also alignment will cause it or brakes.
Hope that helps some,

This "test" will work on the front and rear (without limited slip on rear.)

Simply jack up the front and give the tires a spin and count how many times the tire spins.

If your brakes are dragging it will show up during this test.
