COURSE:

Maintenance and Light Repair III (MLR III)

TASK LENGTH:

1 Hour

 

Replace Stand-Alone Shock Absorbers

Task Description

Standards

Students will:

  • read the linked materials,
  • watch the linked videos using guided notes, and,
  • record a video of themselves describing the steps and tools involved in replacing stand-alone shock absorbers.

 

Safety Note: If possible, students should do this task with a vehicle, but ensure the students do so safely. Lifting the vehicle is not required for the purpose of the student video.

Overall Standard (3): Students will inspect, service, and repair suspension and steering systems.

 

Inspect, remove, and replace shock absorbers; inspect mounts and bushings. (3.23)

 

 Content Understandings

Extending Understandings

Upon successful completion of these tasks students will demonstrate the ability to:

  • Explain why a shock absorber must be replaced.
  • Select the tools required.
  • Describe required safety precautions.
  • Locate the shock absorbers.
  • Locate the bolts to be removed.
  • Describe how to remove and reinstall the top bolt on the shock absorber.
  • Describe how to remove and reinstall the bottom bolt(s).
  • Explain how to compress the new shock absorber to fit in the top and bottom bolt holes.
  • Describe how to know the proper torque for the bolts. 

To move students towards deeper understanding, they should be given opportunities to:

  • Explain why there may be other parts that need to be moved or loosened to replace the shock.
  • Describe how the replacement of struts is different.
  • Explain the visual standard used for compressing the bushings at the top of shock absorber rather than using a torque wrench.

Support Strategies

If students are struggling to access this task, additional supports and strategies could be employed as students are engaging with the task.

Student Reading Guide

 

Shock absorbers need to be replaced on vehicles. A simple test is to push down hard on the trunk or hood directly above the wheel well. If the vehicle bounces up and down more than once it means the shocks need to be replaced. Shock absorbers are always replaced in pairs (front or rear). There are different types of shock absorbers.  This task is about stand-alone shock absorbers. Another type is a shock absorber combined into a suspension strut. These shocks often are inside the spring that supports the vehicle.

 

To remove the stand-alone shock absorbers, first park the vehicle in the appropriate location and jack it up.  Remove the wheels to locate the shock absorbers. 

Old shock absorbers are difficult to remove. Spray the nuts with a metal loosener like WD 40.

Locate the top bolt on the shock absorber and remove the bolt. Consult the service manual on the location of the bolt since they may be in the trunk. Disconnect the shock from the suspension. Remove the shock absorber from the bottom and top bolts.

 

Install the new shock absorbers in reverse order of how the old ones were removed. Fit the new shock onto the suspension control arm. You will need to apply pressure to the squeeze the shock so the bolt holes all fit. Screw the nuts on hand tight. Tighten (torque) to proper specifications.
