NOTE:
- The torsion bar adjusting bolt is coated with Loc-tite(R) that wears off after disassembly. If the torsion bar system is ever disassembled or the torsion bar adjusting bolt is ever removed, use a new torsion bar adjusting bolt when re-assembling.
Adjust the torsion bars (height) as necessary by tightening or loosening the torsion bar adjusting bolt.
1. Tighten the torsion bar adjusting bolt to increase the torque or raise the height.
2. Loosen the torsion bar adjusting bolt to decrease the torque or lower the height.
