Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Ensure all tires are off the ground for proper access to the suspension components.

3. Inspect and Replace Components

Inspect Struts/Shocks:
- Check for oil leakage around the struts or shocks.
- If leaks are present or struts/shocks are damaged, replace them.
- Tools Required: Socket set, torque wrench.
Check Bushings:
- Inspect control arm bushings for cracks or excessive wear. Replace if necessary.
- Parts Required: Replacement bushings (specific to the XC60).
Examine Mounts:
- Look for damage on strut mounts. Replace if they are cracked or broken.
- Tools Required: Impact wrench for easier removal.

4. Reassemble and Lower Vehicle

Once replacements are made, reassemble any removed components.
Ensure all bolts are torqued to manufacturer specifications (consult service manual for torque values).
Carefully lower the vehicle back to the ground.
