42200 TF0 N51 Auto Wheel Hub Bearing Assembly For Honda FIT CITY JAZZ

matters needing attention
Worn or damaged hub bearing or hub unit will cause inappropriate and costly failure of your vehicle on the road, and even harm your safety. Please pay attention to the following matters during the use and installation of hub bearing:
1. In order to ensure safety and reliability to the greatest extent, it is recommended that you always check the hub bearing no matter how old the vehicle is - pay attention to the early warning signal of bearing wear: including any friction noise during rotation or abnormal deceleration of the suspension combination wheel during turning.
For rear wheel drive vehicles, it is recommended that the front wheel hub bearing be lubricated when the vehicle travels to 38000 km. When replacing the brake system, check the bearing and replace the oil seal.

2. If you hear the noise from the hub bearing, first of all, it is important to find the location where the noise occurs. There are many moving parts that may produce noise, or some rotating parts may come into contact with non rotating parts. If the noise in the bearing is confirmed, the bearing may be damaged and needs to be replaced.

3. Because the working conditions leading to bearing failure on both sides of the front hub are similar, even if only one bearing is damaged, it is recommended to replace it in pairs.

4. Hub bearing is sensitive, so it is necessary to adopt correct methods and appropriate tools in any case. During storage, transportation and installation, the components of the bearing shall not be damaged. Some bearings require high pressure, so special tools are required. Be sure to refer to the automobile manufacturing instructions.

5. The bearing should be installed in a clean and tidy environment. The entry of small particles into the bearing will also shorten the service life of the bearing. It is very important to maintain a clean environment when replacing bearings. It is not allowed to knock the bearing with a hammer, and pay attention not to drop the bearing on the ground (or similar improper treatment). Check the condition of shaft and bearing seat before installation. Even slight wear will lead to poor fit and early failure of bearing.

6. For the hub bearing unit, do not attempt to disassemble the hub bearing or adjust the sealing ring of the hub unit, otherwise the sealing ring will be damaged and water or dust will enter. Even the raceway of the sealing ring and inner ring are damaged, resulting in permanent failure of the bearing.

7. There is a magnetic thrust ring in the sealing ring equipped with ABS device bearing, which can not be impacted, impacted or collided with other magnetic fields. Take them out of the packing box before installation and keep them away from the magnetic field, such as the motor or electric tool used. When installing these bearings, observe the ABS alarm pin on the instrument panel through the road condition test to change the operation of the bearings.

8. For the hub bearing equipped with ABS magnetic thrust ring, in order to determine which side the thrust ring is installed, you can use a light and small thing * close to the edge of the bearing, and the magnetic force generated by the bearing will attract it. During installation, point one side with magnetic thrust ring inward and face the sensitive element of ABS. Note: incorrect installation may cause the function of the brake system to fail.

9. Many bearings are sealed and do not need to be greased throughout their life. Other unsealed bearings, such as double row tapered roller bearings, must be lubricated with grease during installation. Due to the different sizes of the inner cavity of the bearing, it is difficult to determine how much grease to add. The most important thing is to ensure that there is grease in the bearing. If there is too much grease, the excess grease will seep out when the bearing rotates. General experience: during installation, the total amount of grease shall account for 50% of the bearing clearance.

10. When installing the lock nut, the torque varies greatly due to different bearing types and bearing seats. Please refer to relevant instructions.

Method of extending the bearing’s lifetime:

1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.

2. Don't allow strong impact, such as hammer striking, transfer roller pressure 

3. Use the accurate installation tool, avoid to use cloth kind and short fibers

4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer

5. General inspection, such as the surrounding temperature, vibrate, noise inspection

6. Keep bearing cleaning from dirt, dust, pollutant, moisture.

7. Bearing should not be ultra cooled.
