How should torsion bars be adjusted after reinstallation?

When adjusting torsion bars after reinstallation, it is important to raise them in an upward direction to prevent settling. This adjustment is necessary because torsion bars provide suspension support by twisting to accommodate load changes. If the bars are not adjusted upward, over time, they can settle due to the weight of the vehicle bearing down on them, which would negatively affect ride height and handling characteristics. Properly adjusting them ensures that the suspension maintains the intended geometry and performance, thereby contributing to a smoother ride and better vehicle handling.

Other options presented focus on unrelated methods that do not align with the mechanics of torsion bar adjustment. Adjusting downward would compromise control and ride quality, while rotating them side to side does not achieve the desired vertical lift necessary for proper suspension function. Suggesting that no adjustment is needed post-installation ignores the natural settling that occurs, which can lead to potential suspension issues over time.
