Underbody Misalignment Check

WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
  1. The dimensions of the underbody must be restored to provide the correct front and rear wheel alignment geometry.
  2. All the dimensions are measured between the centers of the existing holes in the underbody unless otherwise specified.
  3. Inspect all underbody structural members for cracks, twists or bends. Check all welded connections for cracks. Inspect the support brackets for looseness. Carry out any necessary repairs or install new components as necessary.
  4. Underbody dimension tolerances are ± 3 mm (0.12 in).
