Solution

1. Preparation

Gather necessary tools and park the vehicle on a flat surface.
Ensure the engine is off and engage the parking brake.
Wear safety glasses and gloves throughout the process.

2. Inspect Suspension Components

Step 1: Visually inspect the shock absorbers for leaks or damage.
Step 2: Check the condition of the coil springs, looking for cracks or sagging.
Step 3: Examine all suspension bushings for cracks or excessive wear.

3. Tighten or Replace Components

Step 1: Locate bolts on the suspension assembly and use a torque wrench to tighten them to the manufacturer's specifications.
Step 2: If any components are worn, such as sway bar links or bushings, remove and replace them.
- Use a socket set to remove bolts and replace the component with a new one.
- Ensure all new components are torqued to specified values.

4. Test Shock Absorbers

Step 1: Press down on each corner of the vehicle to compress the shock absorbers.
Step 2: Release and observe if the vehicle bounces more than once; if it does, the shock absorbers may need to be replaced.
