Course DescriptionContinues development of skills learned in Undercar I. Introduces basic principles of steering, suspension and wheel alignment for passenger cars and light duty trucks including tire construction, types and sizing. Includes practicing disassembly and re-assembly of steering and suspension system components. Introduces computerized 4-wheel-alignment, tire balancing and tire changing equipment. Prerequisites: CG 209. Audit available.
Addendum to Course Description
This course is designed for students with no previous industry experience. Students will develop the skills, knowledge and attitudes necessary to perform, with supervision, steering, suspension and alignment repairs on import and domestic vehicles. This course will prepare students for Steering Suspension & Alignment II (AM114), where they will practice learned skills on vehicles until they can diagnose and repair these systems with limited supervision. This is the skill level necessary for employment at apprentice level.
The broader purpose of this course is to provide students with authentic experience in basic industry skills and concepts, to help ensure their success in later courses, and on-the-job. These skills include tool use, using service manuals, finding information, fastener tightening and ASE style test taking. Concepts and attitudes that they will put into practice include safety, craftsmanship, professionalism and responsible customer service.
Intended Outcomes for the course
-Perform comprehensive brake, steering and suspension system inspection, maintenance, diagnosis and repairs with limited supervision.
-Communicate effectively with employers, customers and co-workers.
-Access and utilize repair information in a rapidly changing technology.
-Develop and implement strategies and processes to solve steering and suspension system repair problems.
-Perform steering and suspension system repair to professional and ethical standards.
Outcome Assessment Strategies
To reach these goals, students will demonstrate the course outcomes for Steering, Suspension & Alignment I by completing the following tasks:
1. Perform a complete Inspection of the steering & suspension system; and obtain accurate 4-wheel alignment measurements.
Preparation for this will be achieved by completing the following sub-tasks:
• Practice proper inspection procedures for all steering and suspension components
• Practice using industry standard 4-wheel alignment equipment
• Practice using tire mounting and balancing machines
• Overhaul of rack & pinion steering gears
• Removal and replacement of McPherson suspension components
• Removal and replacement of shock absorbers
• Headlamp aiming
2. Demonstrate professional skills and attitudes throughout AM104 by:
• Maintaining good attendance
• Using safe shop practices
• Demonstrating respect for others, and for property
• Participating in and completing all required activities
3. Demonstrate preparedness for ASE testing by achieving passing scores on all written exams
Course Content (Themes, Concepts, Issues and Skills)
Critical to the effective diagnosis and repair of any automotive system is an understanding of how and why certain components work. On today's automobile, this is often more useful for the technician than the ability to perform a particular adjustment or replacement. A technician must have the ability to determine which repairs are in the customer's best interest, and understand how safe service procedures are in their own best interest. To develop this background understanding of automotive steering, suspension & alignment, students in AM104 will explore the following concepts:
Health and Safety
• Loaded suspension components
• Proper jacking & hoisting
• Identification, handling and disposal of lubricants
Professional business and personal conduct
• Customer safety
• Repeat repairs
• Communication with customers
• Customer satisfaction as business strategy
• Cooperative problem solving
• measurements in degrees, inches, metric
• hydraulic principles ¿ pumps / pressure
• static and dynamic imbalance (of tires)
Specific System and Component operation
• vehicle construction
• basic suspension types
• function of suspension system components
• spring types
• electronic suspension types / operation
• steering gear types / operation
• power assisted steering
Skills developed in AM104
In Steering, Suspension & Alignment I, students will build an inventory of the following repair skills to prepare for a career in Automotive Service & Repair. Further skills will be developed and practiced in AM 114, Steering, Suspension & Alignment II.
• remove and replace McPherson struts
• inspect suspension ball-joints for wear
• accurately identify major suspension system components
• remove and replace shock absorbers
• inspect suspension bushings for wear
• evaluate and overhaul rack & pinion type steering gear
• properly select power steering fluid
• inspect steering linkage for wear
• inspect tires for wear and overall condition
• dismount & mount tires / wheels
• use computerized equipment to balance tire/wheel assemblies
• repair tire punctures
1. Perform comprehensive brake, steering and suspension system inspection, maintenance, diagnosis and repairs with limited supervision.
Students check vehicle test results and compare results with manufactures/industry specifications.
1. Develop and implement strategies and processes to solve brake, steering and suspension system repair problems.
2. Communicate effectively with employers, customers and co-workers.
Students work teams communicate with staff to check out tools, school cars, and have repair orders written for lab projects.
Students present a verbal report to the class on a subject of their choice related to current industry technical advances, innovations, safety standards, and/or diagnostic or trouble shooting procedures related to steering and/or suspension.
