The precautions for using automotive steering wheel bearings include the following points:

1. Avoid driving on bumpy, rough or smooth roads, as this can reduce the impact of loads on bearings and extend their lifespan.

2. Avoid prolonged driving under heavy loads or high temperature conditions, as this may lead to bearing wear and even damage, as well as excessively high operating temperatures, resulting in poor lubrication of the bearings and ultimately affecting their lifespan.

3. Ensure to regularly add lubricating oil to the bearings to prevent wear and damage due to lack of oil. In addition, check and replace the lubrication of key components such as the booster pump to keep the oil circuit unobstructed, which can reduce bearing wear.

4. Avoid high-speed driving or sharp turns, as this will intensify the impact on the bearings, leading to rapid wear and even burning of the bearings.

5. Regularly maintain and inspect the vehicle, paying attention to the lubrication of key parts such as the steering knuckle, steering column, and steering shaft sleeve, to avoid wear caused by inadequate lubrication.

6. Ensure that the steering wheel returns smoothly and avoid difficulties in returning.

7. Avoid parking the car in damp, muddy, or heavily polluted environments to prevent water ingress or corrosion of the bearings and reduce their lifespan.

8. Pay attention to driving habits and avoid driving in adverse road conditions and environments, such as driving under the guidance of the vehicle user manual or car mechanic, to maximize the life of the bearings.
