Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather personal safety equipment (gloves, safety glasses).

2. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the front wheels using a socket set.
2. Inspect the brake pads for thickness; replace if less than 3mm.
3. Use a dial indicator or caliper to measure rotor thickness and check for warping. If warped (exceeding 0.002 inches), replace the rotors.
Tools Required: Socket set, caliper, dial indicator.

3. Check Wheel Alignment and Tire Balance

Sub-steps:
1. Use a tire pressure gauge to ensure tires are inflated to manufacturer specifications.
2. Have the vehicle's alignment checked and adjusted as necessary.
3. Balance the tires if uneven wear is observed or if vibrations persist.
Tools Required: Tire pressure gauge, alignment machine (professional equipment).

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and struts for wear or damage.
2. Replace any worn components as needed, following manufacturer specifications.
Tools Required: Jack stands, socket set, torque wrench.
