Solution

1. Preparation

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

2. Inspect Brake Components

Remove the Wheel:
- Use a lug wrench to remove the wheel where the pulling is most noticeable.
- Place the wheel aside safely.
Examine Brake Pads and Rotors:
- Inspect the brake pads for uneven wear; replace if necessary.
- Check the rotor surface for warping or scoring; machine or replace as needed.

3. Brake Caliper Inspection

Check Caliper Function:
- Inspect caliper slide pins for lubrication and movement; clean and lubricate if stuck.
- Ensure caliper pistons retract smoothly; replace caliper if they are seized.

4. Wheel Alignment

Check Alignment:
- Use an alignment rack to measure and adjust the wheel alignment.
- Adjust caster, camber, and toe settings to manufacturer specifications.

5. Suspension Inspection

Inspect Suspension Components:
- Visually check control arms, bushings, and tie rods for wear or damage.
- Replace any worn components to restore proper alignment and handling.

6. Reassemble and Test

Reattach Wheel:
- Install the wheel and torque the lug nuts to the manufacturer’s specifications.
Test Drive the Vehicle:
- Conduct a test drive to ensure the pulling sensation has been resolved.
