ASE A4 Suspension and SteeringWheel Alignment Diagnosis, Adjustment, and RepairEasy
A technician is performing a four-wheel alignment on a vehicle. The alignment machine displays a front left camber of +1.5 degrees and a front right camber of -0.5 degrees. The specification for camber is 0.0 degrees +/- 0.5 degrees. What is the most appropriate initial adjustment for the front left wheel?
- AIncrease positive camber.
- BDecrease negative camber.
- CIncrease negative camber.
- DDecrease positive camber.
Show answer & explanationAnswer & explanation
Correct answer: D. Decrease positive camber.
The front left camber is +1.5 degrees, which is outside the specification of 0.0 degrees +/- 0.5 degrees. To bring it into specification, the positive camber needs to be reduced, or decreased.
Why the other options are wrong
- A. Increasing positive camber would move the measurement further out of specification.
- B. Decreasing negative camber would be relevant if the camber was excessively negative, which it is not.
- C. Increasing negative camber would make the camber more negative, moving it further away from the positive value it currently has.
Camber Adjustment Direction
Camber adjustment involves changing the inward or outward tilt of the wheel relative to the vertical axis, aiming to bring it within manufacturer specifications.
- Positive camber means the top of the wheel tilts outward.
- Negative camber means the top of the wheel tilts inward.
- Adjustments aim to move the current reading towards the specification.
Memory trick: Camber's tilt, spec's the goal; adjust to fit, make the wheel whole.
