Solution

1. Preparation

Gather necessary tools and parts for inspection and repairs.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on the electrical system.

2. Tire Inspection

Remove wheel covers (if applicable) and inspect all tires for uneven wear or damage.
Use a tire pressure gauge to check and adjust tire pressures to the recommended levels.
Rotate tires if uneven wear is present to promote balanced handling.

3. Brake System Inspection

Raise the vehicle using a jack and secure with jack stands.
Remove the wheels to access the brake components.
Inspect brake calipers for sticking or binding; clean or replace as needed.
Check brake pads for wear; replace if they are below the manufacturer’s specifications.
Inspect the brake rotors for warping or damage; replace if necessary.

4. Wheel Bearing and Suspension Check

Spin each wheel by hand to check for smoothness; listen for grinding noises indicating worn bearings.
Inspect suspension components (control arms, bushings, struts) for wear or damage.
Tighten any loose bolts to manufacturer torque specifications.

5. Reassembly and Testing

Reinstall the wheels and lower the vehicle.
Reconnect the battery and clear any fault codes if previously noted.
Conduct a test drive to ensure the dragging sensation is resolved and the vehicle handles properly.
