How do you know when torsion bars need replacing?

Torsion bars may need replacing if you notice a significant drop in ride height, especially on one side of the vehicle, indicating a loss of tension. Additionally, if you experience excessive body roll, poor handling, or unusual noises while driving, these could be signs of worn or damaged torsion bars. Regular inspections for rust, cracks, or deformation can also help identify when they need replacement. If in doubt, consulting a professional mechanic is advisable.
