Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for thickness; replace if less than 3mm.
3. Examine the rotors for grooves or warping; replace if necessary.
Tools Required: Socket set, torque wrench.

3. Check Rotor Runout

Sub-steps:
1. Secure a dial indicator to the brake caliper.
2. Rotate the rotor and measure any deviation from true.
3. If runout exceeds manufacturer specifications, consider replacing the rotor.
Tools Required: Dial indicator, mounting clamps.

4. Inspect Suspension Components

Sub-steps:
1. Visually check control arms, bushings, and tie rods for signs of damage or wear.
2. Perform a physical inspection by shaking the components to check for play.
Parts Required: Replacement suspension components if damaged.

5. Wheel Alignment and Tire Inspection

Sub-steps:
1. Check tire pressure and inspect for uneven tread wear.
2. If necessary, perform a wheel alignment using an alignment machine.
Parts Required: New tires if tread is worn unevenly.
