Steering Issues

[5150]

Okay guys let me give you the lowdown and then I'll ask my question:

-72 2wd Blazer
-20's up front/22's in the rear
-Factory Control Arms, but ALL NEW Suspension Components--Ball Joints, Tie Rod Ends, Both Control Arm Shafts, etc.
-Air Bags
-It is not a factory Power Steering Blazer, so I'm using a 73-87 PS Gear Box.

My steering is WAY too sensitive. It's almost borderline too dangerous to drive. It's like my front wheels are fighting each other. I've had 3 or 4, I forget now, alignments and it still isn't right. I had my last alignment yesterday and watched them do it and everything lined up perfect before they tightened it down. The toe was good and the caster was good. I heard that if if you tighten your gear box down it will help, but do not know if that is correct or not.

Any help from you guys that have had any issues with this is appreciated. Trying to get to the Nashville Goodguys this weekend and don't want to be gripping the steering wheel in fear all the way down there.
