1During a poor-return complaint, the gear and steering linkage move freely when isolated. Steering effort rises at the same point in each column rotation. What should be inspected next?
2Before replacing the steering column on a vehicle with a driver airbag, what should the technician do?
3Technician A says a collapsible steering column helps absorb collision energy. Technician B says a column that has collapsed must be inspected for damage using the manufacturer's procedure. Who is right?
4The steering column has axial play when the driver pulls on the wheel, but the intermediate shaft remains fixed. What should be checked first?
5What fluid should be installed in a hydraulic power steering system?
6A hydraulic steering pump passes its output test, but pressure is normal at the left stop and below specification at the right stop. What does this pattern indicate?
7A vehicle with rack and pinion steering has a power steering fluid leak. The leak appears to be coming from the area where the steering column connects to the steering gear. What component is most likely leaking?
8When adjusting a conventional (non-rack and pinion) steering gear, what two adjustments are typically made?
9Which step protects a hydraulic pump while exchanging power steering fluid?
10A vehicle equipped with electric power steering (EPS) has intermittent loss of power assist. Technician A says a failing torque sensor could be the cause. Technician B says a poor ground connection could be the cause. Who is right?

ASE A4: Suggested Study Strategy
Frequently Asked Questions
How hard is the ASE A4 Suspension and Steering exam?
ASE does not publish an official A4 pass rate. The test requires hands-on experience combined with theoretical knowledge, and it measures practical diagnostic skills and alignment knowledge.
How many questions are on the ASE A4 exam?
The ASE A4 test has 50 questions: 40 scored plus 10 unscored research questions, with a 60-minute time limit. The research questions gather statistics for future tests and are not identified, so answer every question. ASE reports pass or fail and does not publish a fixed cut score.
What experience do I need to take the ASE A4 exam?
ASE recommends 2 years of on-the-job experience in suspension and steering repair before testing. However, you can take the exam without experience. If you pass without meeting experience requirements, you receive certification once you complete the experience. Formal training from an automotive program can substitute for part of the experience requirement.
How do I become an ASE Master Technician?
To become an ASE Master Automobile Technician, you must pass all eight A-series exams: A1 Engine Repair, A2 Automatic Transmission/Transaxle, A3 Manual Drive Train and Axles, A4 Suspension and Steering, A5 Brakes, A6 Electrical/Electronic Systems, A7 Heating and Air Conditioning, and A8 Engine Performance. Certifications are valid for 5 years.
How much does ASE certification cost?
The ASE A4 test costs $62, plus a $34 registration fee per order (you can buy several tests in one order for a single registration fee). A recertification test also costs $62, and recertification tests are capped at $186 per order. Many employers reimburse ASE certification costs as part of their technician development programs.
