9-94 BODY SERVICE
UNDERBODY DIMENSIONS
Each underbody component affects strength of vehicle itself as well as wheel alignment (toe-in, camber, caster).
It is essential, therefore, to check underbody carefully and perform welding properly, if necessary for its correction
or replacement. When damage is found in sealing or rust proof treatment, it is mandatory to correct it properly.
For sealing and rust proof treatment, refer to "ANTI-CORROSION TREATMENT" in this section.
