Do you have aftermarket suspension installed? Lowering springs, coilovers, etc? If you can't get into factory specs with the factory suspension, you might have some bent parts.
For clarification, the bolts may not seem frozen, but they may spin with the rubber in the bushing and give a false indication they are not frozen. If they don't spin freely 360 degrees without tearing the bushing, they need to be replaced. If they do, I'm wondering if you have a bigger problem.
