To Remove:
1) Before servicing the vehicle, refer to the Precautions Section.
2) Remove the torsion bar cover plate.
NOTE: Before relieving the torsion bar tension, measure and record the measurement of the torsion bar adjustment bolt. This measurement will be used as the preset depth for the new torsion bar adjustment bolt during installation.
3) Relieve the torsion bar tension.
A) Position the Torsion Bar Tool and adapters.
B) Tighten the Torsion Bar Tool until the torsion bar adjuster lifts off the adjustment bolt.
CAUTION: The torsion bar adjustment bolt is coated with dry adhesive; and must be replaced if it is backed off or removed. Failure to do so can cause the adjustment bolt to loosen during operation and cause a loss of vehicle alignment.
