To determine if a control arm needs to be replaced, the following methods can be used for inspection:

1. Check if there is any obvious wear, crack, or deformation in the control arm and its components connecting it to the suspension system. Check for any crack, dry fracture, or excessive wear on the sleeve of the control arm.

2. Pay attention to any abnormal noise when driving such as clattering or creaking sound on bumpy roads, which may be a sign of wear of the control arm or its sleeve.

3. If the vehicle swings or is unstable in direction during driving, or if it has uneven tire wear, the control arm may have a problem.

4. Use a dedicated four-wheel alignment device for testing. If any abnormal alignment parameter of the vehicle is discovered, it may result from wear of the control arm or its components.

5. Shake the wheels with hands when lifting the vehicle to check for looseness. If there is obvious sway, the control arm may have a problem.

6. Regular full inspections at professional repair shops can discover potential issues of the control arm in advance and enable timely replacement.
