Design Criteria:
- Design of Suspension Installation needed to be completed in 4 weeks to ensure adequate time to order parts.
- Suspension Installation Diagram and Articulation Layout was completed to verify shock mounting positions, interaxle driveline lengths and required bumpstops. Clearances to frame and crossmembers were also verified.
- Torque rods and transverse control rods were designed and positioned to provide the least bushing loading through full suspension travel and inner and outer frame plates were used to distribute the transverse loading through the torque rods into the frame.
