Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and flashlight.
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.

2. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench.
Inspect brake pads for thickness and wear.
- If the pads are worn down to the wear indicators or less than 3mm, replace them.
Clean the brake calipers and rotors with brake cleaner to remove dust and debris.
Install new brake pads ensuring they are seated properly in the caliper bracket.
Reinstall the wheel and torque lug nuts to the manufacturer’s specification (typically 80-100 lb-ft for XC90).

3. Examine Suspension Components

Perform a visual inspection of the suspension components including control arms, bushings, and struts.
Check for cracks or unusual wear on rubber bushings; replace if necessary.
If struts or shocks are leaking or damaged, replace them following the manufacturer’s guidelines.
Reassemble any components and ensure all bolts are tightened to specification.

4. Inspect and Replace Wheel Bearings (if needed)

Remove the wheel and brake components to access the hub assembly.
Check for play in the wheel by hand; any looseness indicates a bearing issue.
Remove the hub assembly if bearings need replacing, following specific disassembly procedures.
Install new bearings and reassemble everything in reverse order, ensuring components are torqued correctly.
