ASE G1 Auto Maintenance and Light RepairSuspension and SteeringMedium
A technician is performing a pre-alignment inspection. They notice that the vehicle's ride height is significantly lower on one side compared to the other. What is the MOST immediate concern this condition raises regarding the alignment process?
- AIt will lead to inaccurate camber and possibly toe readings.
- BIt suggests an immediate need for tire rotation.
- CIt indicates a worn steering rack, requiring replacement.
- DIt will cause excessive positive caster on the lower side.
Show answer & explanationAnswer & explanation
Correct answer: A. It will lead to inaccurate camber and possibly toe readings.
Uneven ride height directly affects the suspension geometry, leading to inaccurate camber and toe readings if an alignment is performed without correcting the height issue first. Alignment should always be performed at the correct ride height.
Why the other options are wrong
- B. Tire rotation is a maintenance item and not directly related to or a solution for uneven ride height affecting alignment.
- C. Uneven ride height is typically a spring or shock absorber issue, not directly indicative of a worn steering rack.
- D. While ride height can affect caster, the primary and most direct impact on alignment readings is on camber and toe.
Ride Height and Alignment
Correct vehicle ride height is crucial for accurate wheel alignment measurements, as suspension geometry is designed to function optimally at its specified height.
- Uneven or incorrect ride height distorts camber and toe angles.
- Suspension components like springs or shocks affect ride height.
- Ride height must be checked and corrected before performing an alignment.
Memory trick: Level ground, level car, level readings.
