2. Inspect all suspension mounting points and bolts.
3. Tighten any loose bolts to the manufacturer’s specifications using a torque wrench.
4. Recheck for any signs of wear on bushings and joints in the suspension system.

3. Replace Worn or Damaged Components

Tools Required: Socket set, wrench set, spring compressor (if replacing struts/shocks)
Sub-steps:
1. If any components are found to be damaged or excessively worn (e.g., struts, shocks, control arm bushings), remove the old part.
2. Replace with OEM or quality aftermarket parts, ensuring all components match the specifications for the XC60.
3. Reassemble the suspension and ensure all connections are secure and properly torqued.

4. Test Drive

Sub-steps:
1. Lower the vehicle and remove wheel chocks.
2. Conduct a test drive over bumps to verify that the rattling noise has been eliminated.
