Disconnect the battery for safety.

2. Inspect Suspension Components

Sub-steps:
1. Remove the wheel to access the suspension.
2. Visually inspect struts and shocks for leaks or physical damage.
3. Check control arms and bushings for excessive wear or cracks.
4. Use a pry bar to test for play in components; replace any damaged parts.

3. Examine CV Joints and Axles

Sub-steps:
1. Remove the wheel and inspect the CV boot for tears or grease leakage.
2. Check the CV joint for any play by moving it up and down.
3. If damage is found, remove the axle and replace the CV joint or axle assembly as necessary.
