Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure vehicle is on a level surface and secure it with jack stands.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Components

Sway Bar Links:
- Remove the bolts securing the sway bar links to the sway bar and control arm using a socket set.
- Inspect the bushings for wear and replace if necessary.
- Install new sway bar links and tighten bolts to the manufacturer's specified torque (usually around 40-50 Nm).
Shock Absorbers:
- Remove the lower bolts from the shock absorber using a socket set.
- Access the upper mount by removing the interior trim or components obstructing access.
- Replace the shock absorbers with new units, ensuring they are the correct type for the XC60.
- Tighten all bolts to the manufacturer's torque specifications (usually around 60-70 Nm for lower bolts).
Control Arms:
- Remove the wheel to access the control arm bolts.
- Detach the control arm from the subframe and hub assembly by removing the securing bolts.
- Inspect bushings and ball joints for damage; replace if necessary.
- Install the new control arm and secure it with bolts, ensuring to torque them to the specified settings.

3. Final Assembly

Reinstall the wheel and lower the vehicle to the ground.
Reconnect the battery.
Ensure all tools are removed from the work area.
