To change the wheel bearings in a 1989 Ford Laser, start by lifting the vehicle and removing the wheel. Then, detach the brake caliper and rotor to access the hub assembly. Use a bearing puller to remove the old bearings from the hub, clean the area, and install new bearings with proper grease. Reassemble the components in reverse order, ensuring everything is securely tightened.
