Solution

1. Preparation

Gather tools and parts:
- Tools Needed: Jack, jack stands, lug wrench, torque wrench, dial indicator, brake cleaner, caliper tool.
- Safety Warnings: Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Remove Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it on jack stands.
Remove lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors (if warped)

Inspect: Use a dial indicator to check for rotor warp.
Replace: If warped, remove the caliper by unbolting it from the mounting bracket, and then remove the rotor.
- Tools Required: Socket set.
- Torque Specification: Refer to the vehicle manual for the correct torque values when installing new rotors.
Install: Place the new rotor on the hub, reattach the caliper, and tighten bolts to specification.

4. Inspect and Replace Brake Pads

Remove the caliper to access brake pads.
Check the thickness of the pads; replace if below the minimum specification.
Use a caliper tool to compress the caliper piston before installing new pads.
Reassemble caliper and ensure it's securely fastened.

5. Check Suspension Components

Inspect control arms and bushings for wear or damage.
Replace any worn components as necessary, following manufacturer specifications.

6. Reassemble and Lower Vehicle

Reinstall wheels and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to specification.
Ensure all tools are removed from the engine bay and wheel wells.
