The Bravada is sensitive to wheel compensation procedures when using Hunter 4-wheel computerized alignment equipment. Hunter C, D, F, G, H, and
J111 models will not tolerate the movement of more than one head at a time during the compensation procedure and also require that all heads remain
vertical to obtain correct readings.
These requirements cannot be satisfied because of the viscous clutch in the Borg Warner 4472 transfer case. The result of these incorrect readings will be
inaccurate toe settings that could generate customer complaints.
Owners of these types of alignment machines can resolve this condition with the installation of revised Hunter computer software. This software is
available through Hunter Engineering Company. Telephone (314) 731-3020 or contact your local Hunter service representative for details.
Dealers who own other brands of alignment equipment should check witih their manufacturer's representative to ensure that their equipment is not
similarly affected.
