I have an '99 Yukon SXT 1500 4WD. Especially at higher highway speeds, there is a "grab" when steering to the right. It was much more pronounced but I have since purchased new tires and installed new shocks along with a front end alignment. The alignment helped the most but the problem still exits. At this point I'm thinking valve issue or steering box. Any suggestions to help diagnose the problem would be greatly appreciated.
