Objectives and Goals
Students will be able to perform a visual inspection and service on a front wheel drive CV axle.
Activities in this Lesson
- No Power to Wheels - Hooks / Set
As students enter room, the instructor shows a clip of a SRT4 doing a burn out and drag launch. Instructor will have the students write down and describe what they think is wrong or what happened to the vehicle. Instructor will give them about 5-7 minutes to complete this activity while roll is taken.
After a few minutes, the instructor will ask, "How many of you have ever been in a vehicle that runs but does not move, therefore leaving them stranded?" Have a group discussion about this situation to give students an opportunity to share their experiences with the class.
- Inspection How To - Lecture
Instructor will discuss the importance of the front constant velocity axle shaft assmbly and its role in the drivetrain system. Instructor will inform the students of why it is so important to perform front drive axle maintenance on vehicles in order to avoid costly vehicle failures. Instructor will show video clips which include how to inspect CV axle boots, removal and installation of front drive axle assembly, and whether or not they need to be serviced.
Instructor will give the students three (3) inspection sheets, one (1) to complete during the lecture session and the other two (2) will be utilized while in the lab. Students will follow along and take notes during this session to use them and the inspection sheet as a reference during their own front drive axle assembly inspections. Instructor will answer any questions that may arise during this session.

- Check Front CV Axle - Demo / Modeling
Instructor will have students get their safety glasses, sample inspection sheet, and the two (2) remianing blank inspection sheets and follow instructor in the work shop for a demonstration on how to perform an inspection. Instructor will demonstrate where axle boots are located, as well as what to look for (cracks, rips, tears in rubber boot) and how they should be inspected.

- Inspect Front CV Axle - Group Work
Instructor will have students gather into groups of three (3), assign them to a vehicle, and ask them to locate the front drive axle assembly. Once students have done this, I will ask them to follow the procedures demonstrated by me and check the CV inner and outter boots for cracks, tears, leaks. Also indicate condition of axle assembly shaft, and verify if there are trans fluid leaks where axle shaft meets transaxle. Students will need to determine the condition of the axle boots, axle shaft assembly and if any leaks from transaxle exist. Instructor will ask students to record their findings on the inspection sheet during this task. During the inspections and after they have completed their forms, instructor will have students perform spot inspections on other teams work and documentation.
- Clean-up - Closure
I will have students return checked out tools, clean up their work areas, secure vehicles, and ensure that the dirty shop towels are properly disposed of. I will then discuss the importance of tool management and a clean work area as well as verify that their task was done and meets industry standards. I will discuss the following items. Did they understand it and can students perform task? I will inform the students that we will continue with CV axle tear down and CV Boot replacement.
- Assessment Types:
- Demonstrations, Observations,
I will monitor the students during the lecture and ask questions about the material being taught to ensure they understand the information. I will monitor students in the shop and ensure that they are following shop safety as well as assist with task and answer any questions that may arise.
