Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, lubricant (silicone spray), cleaning cloth.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the vehicle to cool before proceeding with inspection.

2. Inspect and Replace Suspension Bushings

Lift the Vehicle: Use a jack to lift the front or rear (depending on where the noise is coming from) and secure with jack stands.
Remove Wheel: Take off the wheel to access suspension components.
Inspect Bushings: Check for cracks or excessive wear in the control arm and sway bar bushings.
Replace Worn Bushings:
- Use a socket set to remove the bolts securing the affected bushing.
- Remove the old bushing and clean the mounting area.
- Install the new bushing, ensuring it is aligned properly.
- Torque the bolts to the manufacturer's specifications (consult repair manual for exact torque values).
Reinstall Wheel: Replace the wheel and lower the vehicle back to the ground.

3. Inspect and Replace Sway Bar Links

Visual Inspection: Check the sway bar links for any signs of wear or damage.
Remove Old Links: If worn, use a socket set to remove the nuts securing the sway bar links to the sway bar and control arm.
Install New Links:
- Position the new sway bar link and secure it with the nuts.
- Torque the nuts to the specified value.
Repeat on All Sides: If necessary, repeat the process for the opposite side.

4. Lubricate Suspension Components

Locate Grease Fittings: Identify any grease fittings on suspension components.
Apply Lubricant: Use a grease gun to apply a suitable lubricant to the fittings.
Wipe Excess: Clean up any excess lubricant to prevent dirt accumulation.
