Solution

1. Preparation

Tools Required: Socket set, jack, jack stands, torque wrench, pry bar, and safety glasses.
Park the vehicle on a level surface and ensure the engine is off. Engage the parking brake.
Allow the vehicle to cool down if it has been recently driven.

2. Inspect and Replace CV Joints (if damaged)

Lift the Vehicle:
- Use a jack to elevate the front of the vehicle and secure it with jack stands.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the front wheel.
Check CV Joint Boots:
- Inspect the outer and inner CV joint boots for any signs of damage or grease leaks.
Replace CV Joint (if necessary):
- If the CV joint is damaged, unbolt the axle from the hub assembly.
- Remove the axle from the transmission side by pulling it out.
- Install the new CV joint by reversing the removal process. Ensure to torque the axle nut to the manufacturer’s specifications (typically around 250 Nm).

3. Inspect and Replace Sway Bar Links (if worn)

- Identify the sway bar links connecting the sway bar to the suspension.
Remove Old Links:
- Use a socket set to unbolt the sway bar links from both the sway bar and the lower control arm.
Install New Links:
- Attach the new sway bar links, ensuring they are properly torqued to specification (usually around 40 Nm).

4. Check Suspension Components (if needed)

Visual Inspection:
- Inspect control arms, bushings, and ball joints for wear or damage.
Replace Worn Components:
- If any components are worn, replace them as necessary, following the vehicle manufacturer’s specifications for torque settings.
