Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Pry bar
Inspection mirror

2. Inspect Suspension Components

Step 1: Raise the vehicle using a jack and secure it with jack stands.
Step 2: Remove the front and/or rear wheel (depending on where the noise is originating).
Step 3: Visually inspect all suspension components including control arms, bushings, shocks, and sway bar links for damage or excessive wear.
Step 4: Use a pry bar to check for play in the bushings and joints.

3. Tighten Loose Components

Step 1: Using a torque wrench, tighten any loose suspension bolts to the manufacturer's specifications.
Step 2: Inspect and replace any worn bushings or sway bar links as necessary.

4. Replace Worn Shocks/Struts (if necessary)

Step 1: If shocks or struts are identified as defective, remove them by unbolting the top and bottom mounting points.
Step 2: Install the new shocks/struts and torque bolts to the specified values.
Step 3: Reinstall the wheel and lower the vehicle to the ground.
