Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using a jack and jack stands.
Wear safety goggles and gloves.

2. Inspect and Replace Sway Bar Links

Sub-steps:
1. Locate the sway bar links connected to the sway bar and the lower control arm.
2. Use a socket set to remove the nuts securing the sway bar links.
3. Remove the old sway bar links and inspect for wear.
4. Install new sway bar links by aligning them correctly and secure with nuts (torque to manufacturer specifications).

3. Check and Replace Shock Absorbers

Sub-steps:
1. Detach the shock absorber from the upper mount (use a wrench for nuts).
2. Remove the lower mounting bolts using a socket set.
3. Pull out the shock absorber and inspect for oil leakage or damage.
4. Install the new shock absorber by reversing the removal steps (torque to specifications).

4. Inspect Control Arms and Ball Joints

Sub-steps:
1. Remove the wheel for better access to suspension components.
2. Check for any play in the ball joints by moving them with your hands.
3. If worn, detach the control arm by removing its mounting bolts.
4. Replace with new control arms and reinstall (torque to specifications).
