1. Remove the tire. After removing the tire, you can see the brake disc and caliper, and only after removing it can you see the front wheel bearing. Remove the bearing retaining nut. Use a screwdriver to remove the dust cover outside the bearing, and you can see the large nut that fixes the bearing. Use a 30mm socket to remove the nut.
2. Remove the brake caliper. Use an 18-inch torx wrench to remove the two screws fixing the brake caliper, and slowly remove the brake caliper to prevent the brake oil pipe from breaking. Remove the brake disc.
3. Remove the outer brake disc. If the brake disc cannot be removed, you can screw two screws on the brake disc hole, tighten the screws with the corresponding wrench, and then the brake disc can be removed.
4. Remove the front wheel bearing. The solid nut on the outside of the bearing has been removed and the bearing can be removed by pulling it out with both hands. Install new bearings. Install new bearings and replace with new strong nuts. After tightening the nuts, rivet the edges of the nuts with openings to make the nuts stronger and install the dust cover.
5. Install the brake disc and brake caliper. Install the brake disc, brake caliper, and replace the bearing this time. Extended information Precautions for automobile front wheel bearings: Pay attention to early warning signs of bearing wear: including whether there is friction noise when turning or abnormal deceleration when the suspension combination wheel turns.
6. If you hear noise from the hub bearing, the first thing to do is to find the location where the noise occurs. Even if only one bearing is damaged, it is recommended to replace it in pairs. Hub bearings are sensitive and require correct methods and the right tools anyway.
7. When installing bearings, it should be done in a clean and tidy environment. Fine particles entering the bearing will also shorten the service life of the bearing. 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.
8. Improper installation of the wheel hub bearing equipped with a magnetic thrust ring may cause the brake system to malfunction. The amount of torque varies greatly due to the different types of bearings and housings used when installing and locking curtains.
9. Improper wheel hubs will lead to increased fuel consumption. At present, domestic car wheel sizes are mainly 12 inches to 22 inches. Under normal circumstances, when car owners replace wheel hubs, it is more appropriate to increase the size and width of the original wheel hubs. In order to take advantage of the wide tires to improve driving comfort and tire grip.
10. However, changing the wheel hub at will will affect the original factory data of the vehicle. Once the wheel hub is modified, it will not only increase the vehicle's fuel consumption, but also affect the vehicle's power and braking effect.
11. In addition, inappropriate wheel hubs will increase tire wear, leaving potential safety hazards for driving. Therefore, you must pay attention when replacing the wheel hub.
