In this segment, instructor Brett Rimer guides student Jessica Kenney through the process of replacing a worn out shock absorber, a vital component of a car's suspension system.

Safety Note: Always wear safety glasses when striking metal.1. Jessica starts by raising the car on a hydraulic lift. Using an impact wrench, she removes the front tire (figure A), exposing the brake assembly and strut, which consists of three main parts: a heavy spring, canister, and a shock absorber. 2. Before she works on the strut, Jessica has to get the brake assembly out of her way. Using a socket wrench, she unbolts the brake caliper, and then hangs it on a wire hook, which helps avoid undue strain on the still-connected brake hose (figure B). With the caliper removed, the brake rotor slides off easily.
3. To disconnect the bottom side of the strut assembly, Jessica first removes a pair of rusty nuts using an impact wrench and knocks out their companion bolts using a hammer (figure C). After lowering the car, she removes the top bolt connections. With the strut assembly free from the car, she carefully inspects the damage (figure D).
4. In order to extract the shock absorber from the strut assembly, Jessica uses a hand-crank compression machine, to press down the spring (figure E).5. She now uses the impact wrench to remove a bolt, and to free the shock absorber from the canister (figure F).
6. After bolting in the new shock absorber, Jessica releases the compression and takes the strut assembly back to the car.7. To reinstall the assembly, Jessica holds it in place with one hand while threading the four top bolts with the other (figure G). 8. After Jessica tightens the top bolts, she again raises the car. This time, the bottom bolts give no trouble as she secures the strut in place (figure H). 9. To complete the replacement project, Jessica replaces the brake assembly and uses a torque wrench to properly tighten the lug nuts on the tire (figure I).
Next, Jessica expands her experience by tackling a brake job.
