ASE G1 Auto Maintenance and Light RepairMaintenance and Light RepairEasy
A technician is performing a pre-alignment inspection on a vehicle. Which of the following conditions, if found, would most likely prevent a proper wheel alignment?
- AA non-functioning horn.
- BLoose or worn steering linkage components.
- CSlightly worn tire tread on one tire.
- DMinor cosmetic damage to a wheel cover.
Show answer & explanationAnswer & explanation
Correct answer: B. Loose or worn steering linkage components.
Loose or worn steering linkage components directly affect the geometry and stability of the steering and suspension system, making an accurate wheel alignment impossible. These components must be in good condition for the alignment to hold.
Why the other options are wrong
- A. A non-functioning horn is an electrical issue and does not affect the mechanical alignment of the wheels.
- C. Slightly worn tire tread, while potentially indicating an alignment issue, does not prevent the alignment from being performed. It's a symptom, not a cause of alignment prevention.
- D. Cosmetic damage to a wheel cover has no impact on the mechanical components or adjustments required for a wheel alignment.
Pre-Alignment Inspection
A thorough check of steering, suspension, and tire components before performing a wheel alignment to ensure the vehicle is in a suitable condition for accurate adjustment.
- Identifies worn or damaged parts that would prevent a successful alignment.
- Ensures alignment adjustments will hold and be effective.
- Includes checking ball joints, tie rod ends, wheel bearings, and tire condition.
Memory trick: Alignment needs a stable foundation; check all connections first.
