Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

a. Check Tire Pressure
- Use a tire gauge to measure the air pressure in all tires.
- Inflate tires to the manufacturer's recommended pressure if needed.
b. Inspect Tires
- Look for uneven wear, bulging, or other visible defects.
- Replace any damaged tires with new ones that match OEM specifications.

3. Suspension Component Inspection and Replacement

a. Inspect Struts and Shocks
- Visually check for leaks or any damage on the struts and shocks.
- If leaking, proceed to replace the struts or shocks.
b. Replace Struts/Shocks
- Tools Required: Socket set, torque wrench, spring compressor, jack stands.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel to access the suspension components.
- Use a spring compressor to safely compress the coil spring if necessary.
- Remove the bolts securing the strut/shock to the vehicle and disconnect it from the lower control arm.
- Install the new strut/shock by reversing the removal process, ensuring all bolts are torqued to manufacturer specifications.

4. Test Drive

After repairs, lower the vehicle and take it for a test drive to ensure the bouncing issue is resolved.
