Back to your original Question. There are at least 2 problems with the original steering configuation. First off I'm assuming you have converted to a solid front axle. The first problem with larger tires on a GM is the frame likes to flex and crack at the steering box. You need to install a steering box brace. This goes from the rear bolts on the steering box to a front crossmember. I assuming you're using 40"+ tires. It you also be a very good idea to install a frame repair kit even before is cracks. This should eliminate any flex. Offroaddesign.com sells both parts. The second problem is with the drag link(s-bar). As the front suspension moves, the drag link moves through an arc causing the front tires to turn without you turning the wheel. This is call bumpsteer and gets worst the more lift you have. Also when offroad, if you flex the right tire up and the left tire down far enough, you will not be able to turn right. The draglink will drop down as far as the suspension allows and the steering box doesn't have enough travel to push the draglink any father to turn right. Left is fine but no right. The ONLY ways fix this are to convert to hydralic steering(nice but very expensive and not DOT legal) and crossover steering. This works because now instead of the draglink connecting the steering box to the driver's side and being about 18" long it now goes from the steering box to the passinger's side and is about 5' long. This means as the suspension cycles, the arc that the draglink travels through is extremely reduced, thus almost no bumpsteer and no more right turn problem. Offroaddesign.com and oru.com both sell crossover kits. You will need to have you passinger's side steering knuckle machined to accept a steering arm and switch to a 2wd steering box. Everything else is in the kit. Hope this helps.
