The following components are supported by a front crossmember frame which is rigidly bolted to the body rail at 4 locations:
| • | Front suspension lower control arms |
The following components are supported by the rear suspension frame which is attached to the body rail through rubber insulators at 3 locations:
| • | Rear suspension components |
The underbody frames must be properly aligned to maintain the correct suspension and wheel alignment.
The individual underbody components contribute directly to the overall strength of the unibody. Use proper welding techniques during service repair operations. Refer to
Approved Equipment for Collision Repair Caution for welding information and for vehicle preparation.
The components must be corrosion protected whenever body repair operations damage or destroy the original sealing surfaces. Use a two-part catalyzed primer such as PPG DP40 or equivalent when corrosion protection is needed to welded surfaces. Apply
the sealers and anti-corrosion materials as necessary. Refer to
Anti-Corrosion Treatment and Repair. Do not combine paint systems. Refer to
Basecoat/Clearcoat Paint Systems for further information.
