How do you make the wheels of a truck turn freely?

To make the wheels of a truck turn freely, ensure that the wheel bearings are well-lubricated and in good condition, as worn or dry bearings can cause friction. Check the alignment and balance of the wheels to prevent drag and ensure smooth rotation. Additionally, inspect the brake system to ensure that the brake pads are not sticking or causing resistance. Regular maintenance and tire inflation also play vital roles in ensuring free wheel movement.
