Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Remove Wheel and Inspect Brakes

Sub-steps:
1. Loosen lug nuts slightly while the car is on the ground.
2. Lift the car using a jack and support it with jack stands.
3. Remove the wheel completely.
4. Inspect the brake rotor for warping using a dial indicator. If warped, replace the rotor.
5. Check the brake pads for uneven wear; replace if necessary.

3. Replace Brake Rotors (if warped)

Sub-steps:
1. Remove caliper bolts using a socket wrench and hang the caliper without straining the brake line.
2. Remove the old rotor and clean the hub surface.
3. Install the new rotor and ensure it's seated properly.
4. Reattach the caliper and tighten bolts to manufacturer specifications (typically 25-30 ft-lbs).

4. Inspect and Replace Suspension Components (if needed)

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Replace any worn control arms, bushings, or tie rods using appropriate removal tools (e.g., ball joint separator).
3. Reassemble and tighten all fasteners to specified torque values.

5. Wheel Alignment and Balance

Sub-steps:
1. After reassembly, take the vehicle to a professional for a wheel alignment and balance check.
2. Adjust alignment settings to manufacturer specifications.
