Frame Assembly
Underbody misalignment can affect front and rear wheel alignment, the operation of the suspension parts and drivetrain operation. Window glass cracks, door and window opening concerns, and air or water leaks at the doors are often caused by improperly tightened bolts and body misalignment.
Every structural member and outer panel is designed to offer the maximum protection in the event of a collision.
Body Misalignment Check
1. CAUTION: Do not attempt to correct any serious misalignment with one pulling/pushing operation. Damage to structure may occur.
NOTE: All body alignment measurements are made without trim and from metal to metal.
To check the body alignment, take two opposite diagonal measurements between the front, center or rear pillars. Take the measurements between reference points, such as crease lines or weld joints which are diagonally opposite each other on the two pillars being measured.
