Virginia State Inspection Practice Test

Which modifications to the front end suspension lead to rejection during inspection?

1. Use of lift blocks

2. Use of shims for alignment

3. Overall suspension height increase

4. Use of unapproved aftermarket parts

The correct answer is: Use of shims for alignment

Using shims for alignment is a practice commonly associated with trying to fine-tune the geometry of the suspension system, particularly for camber and caster adjustments. However, altering the suspension alignment in an unconventional manner can lead to issues with vehicle handling and safety. If shims are not used according to manufacturer specifications or are deemed unsafe or improper, this can be a reason for rejection during inspection. Modifications that fundamentally alter the suspension system, such as the use of lift blocks, increasing overall suspension height, or using unapproved aftermarket parts, can significantly compromise vehicle stability, safety, and structural integrity. Many regulations focus on ensuring that vehicles are equipped with components designed to work together safely. Therefore, while shims may seem like a minor adjustment, using them improperly can fail to meet the safety standards required for passing inspection.
