Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use jack stands to support the vehicle securely after raising it.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Remove the wheel to access brake components.
Check Rotors:
- Inspect rotors for warping or scoring using a straight edge or rotor gauge.
- If warping is present, replace the rotors.
Replace Rotors:
- Remove caliper bolts using a socket set and hang the caliper using a wire hook (do not let it hang by the brake line).
- Remove the old rotor and install the new rotor, ensuring it is properly seated.
- Reattach the caliper and torque bolts to manufacturer specifications (e.g., 20-25 ft-lbs).

3. Inspect and Replace Brake Pads (if necessary)

Remove Brake Caliper:
- Follow the same procedure to unbolt the caliper.
- Pull out the old brake pads.
Install New Pads:
- Compare new pads with old ones to verify correct size.
- Insert the new pads into the caliper bracket.
Reassemble Caliper:
- Reattach the caliper over the new pads and torque the caliper bolts.

4. Check Suspension Components

Visual Inspection:
- Inspect bushings, tie rods, and ball joints for any signs of wear or damage.
Replace Worn Parts:
- If any components are found to be defective, replace them with OEM or quality aftermarket parts.

5. Wheel Alignment and Balancing

Balance Wheels:
- Take the vehicle to a professional to balance the wheels if needed.
Check Alignment:
- Ensure proper wheel alignment to prevent future issues.
