What must be done to fix alignment during vehicle repair?

To effectively fix alignment during vehicle repair, using special control points is essential. Special control points are specific predetermined locations on the vehicle's frame that serve as reference markers during the alignment process. They allow technicians to measure and assess the vehicle's dimensions accurately, ensuring that all components are adjusted to meet the manufacturer's specifications.

By adhering to these control points, an appraiser or technician can ensure that the structural integrity and geometry of the vehicle are restored. This process is vital for ensuring proper wheel alignment, which affects handling, tire wear, and overall safety. Proper alignment not only improves vehicle performance but also extends the lifespan of various components.

In contrast, discarding affected parts may lead to unnecessary replacements and costs without addressing the underlying alignment issue. Replacing the entire frame is a drastic and often unnecessary step, as most alignment issues can be resolved through adjustments. Relying solely on visual inspections lacks the precision required to accurately identify and correct alignment problems, potentially resulting in inadequate repairs. Thus, utilizing special control points provides a systematic and precise method for achieving proper vehicle alignment.
