Underbody Misalignment Check: Notes
NOTE:
Underbody misalignment can be the result of damage or loose frame components. It can affect front and rear wheel alignment and cause incorrect operation and abnormal wear of tires and chassis parts.
NOTE:
Refer to the Body Builders Book for dimensional data when performing repairs on the cab or frame.
- Inspect the frame for damage and loose parts before checking the frame alignment.
- Inspect all crossmembers for cracks, twists or bends.
- Inspect all of the welded connections for cracks. For repairs, refer to WELD ATTACHMENT in this article.
- Check all of the support brackets for looseness. If the brackets are loose, tighten to specification.
