The front wheels of the Fiesta are mounted on double-row ball bearings, while the rear axle is fitted with maintenance-free tapered bearings. The bearings in the rear wheel hubs are virtually wear-free. If installed correctly, their service life is over 150,000 km. The front wheel hub bearings, which are subject to heavy loads, have a much shorter service life and are replaced as a set if damaged. If the bearings are damaged, immediately pay attention to the noise and knocking coming from the wheel hubs. A grinding noise when turning to the right means that the front left bearing is damaged, while noise and knocking when turning to the left indicate a damaged right bearing. It is better to have them replaced at a car repair shop: the bearings, rotating rings, hub and steering knuckle are manufactured with high precision, and qualified repairs are impossible without special tools.
SEQUENCE OF WORKS
1. Place the car on a horizontal asphalt surface. Grasp the upper edge of the wheel and try to rhythmically move it toward the center and outward of the car. If there is no play or noise, the bearings are in good condition.
2. If the front wheel has play, have an assistant press the brake pedal and repeat the check. If the wheel play remains, the ball joint of the lower transverse arm of the front suspension is worn.
