Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Suspension Components

Control Arms and Bushings:
- Remove the wheel to access the control arm.
- Use a socket set to unbolt the control arm from the chassis and the wheel hub.
- Inspect bushings for cracks or excessive wear; replace if necessary.
- Install new control arms or bushings, ensuring proper alignment. Torque bolts to manufacturer specifications (typically around 70-90 Nm).
Ball Joints:
- Remove the cotter pin and castle nut from the ball joint.
- Use a ball joint separator tool to detach the ball joint from the steering knuckle.
- Install the new ball joint and secure it with the castle nut and cotter pin. Torque to manufacturer specifications (usually about 50-60 Nm).

3. Check and Replace CV Joints

Inspect the outer and inner CV joints for any torn boots or grease leakage.
If damaged, remove the axle by unbolting it from the wheel hub and differential.
Replace the CV joint or the entire axle assembly as needed. Ensure proper alignment and secure with specified torque.

4. Inspect and Replace Sway Bar Links

Locate the sway bar links on both sides of the vehicle.
Unbolt the sway bar link from the sway bar and the control arm using appropriate socket sizes.
Replace with new sway bar links and torque bolts to manufacturer specifications (generally around 25-35 Nm).
