Front end alignment.
Check your weight on the rig; open your driver door and look at the yellow sticker. See how many pounds you're allowed to bring. That number on the door is for everything you put IN the rig; including yourself and family. Take the rig to a CAT scale and run it across the scales; see if you're too heavy on one of the axles or in total.
Check your Hellwig helper springs. More here:

As others have noted, make sure you're not hanging too much weight off the tail, thus unloading your front end. CAT scales will tell you all you need to know about this too.
