- Use a jack to lift the front of the vehicle and secure it with jack stands.
Step 2: Inspect Suspension Components
- Visually inspect the tie rod ends, ball joints, and control arms for wear or damage.
- Use a pry bar to check for play in the joints.
Step 3: Replace Worn Components
- If any components (e.g., tie rod ends, ball joints) are found to be worn:
  - Remove the retaining nut and bolt for the component.
  - Use a ball joint separator if necessary.
  - Install the new component and torque to manufacturer specifications (typically around 40-50 ft-lbs).
  - Reconnect any removed parts and ensure they are secure.

3. Sway Bar Link and Bushing Replacement

Step 1: Inspect and Remove Sway Bar Links
- Check the sway bar links for wear.
- Remove the bolts securing the sway bar links to the sway bar and lower control arm.
Step 2: Install New Sway Bar Links
- Attach the new sway bar links, ensuring they are oriented correctly.
- Torque the bolts to manufacturer specifications (around 20-30 ft-lbs).
