Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, brake cleaner, torque wrench, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Rotors

Step 1: Remove the wheel using a lug wrench.
Step 2: Inspect the brake rotor for warping or grooves.
- Use a dial indicator to measure rotor runout if necessary.
Step 3: If rotors are worn or damaged, remove the caliper (using a socket set) and hang it securely.
Step 4: Remove the rotor by unscrewing any retaining screws or using a slide hammer if necessary.
Step 5: Install new rotors, ensuring they are cleaned with brake cleaner.
Step 6: Reattach the caliper and wheel, torque to manufacturer specifications.

3. Inspect and Replace Brake Pads

Step 1: With the wheel still off, check the brake pads for thickness.
Step 2: If worn, remove the caliper and old pads.
Step 3: Install new brake pads, ensuring they are properly seated.
Step 4: Reattach the caliper and wheel, torque to manufacturer specifications.

4. Inspect Suspension Components

Step 1: Visually inspect control arms, bushings, and struts for any signs of wear or damage.
Step 2: Replace any worn components as needed, following manufacturer guidelines for installation and torque specifications.

5. Wheel Alignment and Balance

Step 1: After all components are replaced, have the vehicle's wheel alignment checked.
Step 2: Balance the wheels if necessary to ensure proper handling.
