ASE A4 Suspension and SteeringWheel Alignment Diagnosis, Adjustment, and RepairEasy
A technician is performing a four-wheel alignment. After completing all adjustments, the alignment machine displays a front 'total toe' of +0.10 degrees. The specification for total toe is +0.08 to +0.12 degrees. Which of the following statements is true regarding this reading?
- AThe total toe is out of specification and requires adjustment.
- BThe individual toe settings for each wheel must be checked before making a decision.
- CThe total toe is within specification and does not require adjustment.
- DA positive total toe indicates excessive toe-out.
Show answer & explanationAnswer & explanation
Correct answer: C. The total toe is within specification and does not require adjustment.
The measured total toe of +0.10 degrees falls within the specified range of +0.08 to +0.12 degrees. Therefore, no further adjustment is needed for total toe.
Why the other options are wrong
- A. The reading is within the specified range, so this statement is incorrect.
- B. While individual toe settings are important, the question specifically asks about the total toe reading which is within spec. If total toe is within spec, individual toe often is as well, or at least acceptable.
- D. A positive total toe indicates toe-in, not toe-out. Toe-out is indicated by a negative total toe reading.
Total Toe Specification
The acceptable range for the combined toe-in or toe-out of both wheels on an axle, crucial for tire wear and straight-line stability.
- Measured as a sum or difference of individual toe.
- Expressed in degrees or inches.
- Ensures proper tire rolling and minimizes scrubbing.
