Thank you for responding, BigBlock. My truck is all 100% stock, bought it new. No mods whatsoever. It's got 167K miles on it, and luckily only had to replace fuel pump twice and an alternator once. It's even on its stock brakes!
I never noticed until now that there are no adjustment bolts in place for the torsion bars. The front is slightly lower than the rear, but it doesn't look abnormal. And it rides pretty stiff, but not too uncomfortably. I am actually finally replacing all the front-end suspension components - Pitman Arm, Idler Arm, Upper Control Arms, Lower Ball Joints, and Inner & outer tie rods, that's when I noticed there were no bolts there for the torsion bars. But once all that is done, I will be getting an alignment, so I will be interested in what they say about it. Thanks again!
