Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Suspension Bushings

Tools Required: Socket set, torque wrench, pry bar, lubricant.
Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel on the side where the noise is occurring.
3. Locate the suspension bushings connected to the control arms and sway bar.
4. Use a pry bar to carefully remove the old bushings from their seats.
5. Apply a silicone-based lubricant to the new bushings before installation.
6. Install the new bushings and ensure they are seated properly.
7. Torque the bolts to the manufacturer's specifications.

3. Inspect and Replace Shock Absorbers (if necessary)

Tools Required: Socket set, torque wrench, spring compressor (if needed).
Sub-steps:
1. With the vehicle still on jack stands, locate the shock absorbers.
2. Remove the mounting bolts from the upper and lower ends of the shock absorber.
3. Carefully remove the old shock absorber from its mount.
4. Install the new shock absorber and tighten the bolts to the specified torque.
5. Repeat for the opposite side if both shocks are worn.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Remove the jack stands and lower the vehicle to the ground.
3. Torque the lug nuts to the manufacturer's specifications.
