Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, dial gauge, torque wrench, brake cleaner, and OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Brake Rotors

Sub-step 1: Remove the wheel using a lug wrench.
Sub-step 2: Remove caliper bolts and carefully lift the caliper off the rotor. Support it with a bungee cord or similar device to avoid stress on the brake line.
Sub-step 3: Remove the rotor from the hub. Inspect for warping using a dial gauge; a variance greater than 0.002 inches indicates warping.
Sub-step 4: If warped, replace the rotor with a new one, ensuring it is properly aligned.
Sub-step 5: Reinstall the caliper and torque bolts to manufacturer specifications (typically around 20-25 lb-ft).

3. Check and Replace Brake Pads

Sub-step 1: Inspect brake pads for uneven wear; if worn below 3mm, replace them.
Sub-step 2: Clean the caliper bracket and apply brake grease to prevent squeaking.
Sub-step 3: Install new brake pads and ensure they are seated evenly.

4. Inspect Suspension Components

Sub-step 1: Lift the vehicle and support it with jack stands.
Sub-step 2: Check tie rods, ball joints, and control arms for excessive play or damage.
Sub-step 3: Replace any worn or damaged components as necessary.

5. Perform Wheel Alignment and Balance

Sub-step 1: Take the vehicle to a professional service or use an alignment machine.
Sub-step 2: Adjust the alignment settings to manufacturer's specifications.
Sub-step 3: Balance the wheels if necessary to eliminate vibrations.
