Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, mechanic’s stethoscope.
Raise the vehicle using the jack and secure it with jack stands.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Inspect Suspension Components

Sub-steps:
