2. Inspect and Tighten Suspension Components

Sub-steps:
- Remove the front wheel using a socket set.
- Inspect the lower control arm, strut mounts, and sway bar links for damage.
- Tighten all bolts and nuts associated with the front suspension using a torque wrench to the manufacturer’s specifications (refer to the service manual for specific torque values).

3. Replace Worn Components

Sub-steps:
- If any components (e.g., bushings, struts, sway bar links) are found to be worn or damaged, replace them.
- Remove the affected component by loosening any retaining bolts or clips as necessary.
- Install the new part in the reverse order of removal, ensuring all connections are secure and torqued to specifications.

4. Alignment Check

Sub-steps:
- After replacing any components, perform a wheel alignment using alignment equipment.
- Adjust caster, camber, and toe settings to the manufacturer specifications.
