car slants to the right only in the front

fire up the impact and give the bolt a spin.

First, this is a surefire way to strip the living crap out of the torsion bar adjuster threads, ruining the adjuster.

Second, the adjusters should turn pretty easily as long as the the weight of the car is off the front wheels. A little WD-40 should help this along. There's no reason to use an impact on these. If they're that messed up, you need new ones. And a few complete turns will raise or lower the car significantly, its not like you need to crank on them for hours to raise the car a 1/2". And, just to clarify, you should NEVER make changes to the adjusters while there's weight on the front wheels, so this should be super easy.

Finally, righty tighty, lefty loosey. Tightening the adjusters raises the car, loosening them lowers it.

And the reason why no one said "just tighten up the torsion bar adjusters" is because a car won't go from sitting level to sitting low on one side unless there's a reason, ie, something is broken. Which is why we all suggested that the OP inspect his suspension to find out what was wrong before just arbitrarily adjusting the torsion bars.
