Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheels

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is still on the ground.
2. Lift the vehicle using a hydraulic jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheels.
Tools Required: Lug wrench, hydraulic jack, jack stands.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Measure rotor thickness and check for warping using a runout gauge.
2. If rotors are below spec or warped, remove the caliper by unscrewing the caliper bolts.
3. Slide off the rotor and replace it with a new one, ensuring it fits properly.
4. Reinstall the caliper and torque bolts to manufacturer specifications (usually around 30 Nm).
Tools Required: Socket set, torque wrench, runout gauge.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper to access the brake pads.
2. Check pads for wear; if below minimum thickness (usually 3 mm), replace them.
3. Clean the caliper bracket and apply brake grease to contact points.
4. Install new brake pads and reattach the caliper.
Tools Required: Socket set, brake cleaner, brake grease.

5. Check Suspension Components

Sub-steps:
1. Inspect ball joints, tie rods, and control arms for any signs of wear or damage.
2. Replace any worn components as necessary.
3. Ensure all bushings are intact and free of cracks.
Tools Required: Wrench set, torque wrench.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to manufacturer specifications (usually around 120 Nm).
3. Conduct a test drive to ensure the issue is resolved.

Tools Required: Torque wrench, lug wrench.
