Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Tools Required: Jack, jack stands, tire pressure gauge, socket set, torque wrench.

2. Inspect and Replace Tires (if needed)

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure and adjust to the recommended PSI.
2. Inspect the tread depth and look for uneven wear patterns; replace any damaged tires.
3. If new tires are needed, remove the old tires using a socket set, and install the new tires, ensuring they are properly torqued to the manufacturer's specifications.

3. Inspect and Replace Shock Absorbers/Struts (if needed)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the suspension components.
3. Inspect the shocks/struts for leaks or physical damage. If damaged, disconnect the upper and lower mounting bolts and remove the old shock/strut.
4. Install new shock absorbers/struts and torque the bolts to the manufacturer's specifications.

4. Perform Wheel Alignment

Sub-steps:
1. After replacing the shocks/struts, take the vehicle to a professional alignment shop.
2. Ensure that the alignment is adjusted according to the manufacturer's specifications to prevent further bouncing issues.
