If the car wheel hub bearings have been used for a long time or have malfunctioned and need to be replaced, the steps for replacing the car wheel hub bearings are as follows:
The first step is to prepare the tools and accessories. Including: bearings, bearing sleeves, wrenches, lubricants, and sandpaper.
Step 2, use a jack to lift the vehicle and ensure its stability.
Step three, remove the tire and place it in a safe place.
Step 4, remove the wheel hub cover and carefully remove the nut that fixes the wheel hub bearing. It should be noted that this step is important because if the nut is loose, it may cause damage to the bearing.
Step 5, place the bearing sleeve on the fixed ring of the bearing and use a wrench to rotate the sleeve until the bearing becomes loose.
Step 6, remove the old bearings and check for any damage or wear. If the bearings are severely worn, you need to replace them with new ones.
Step 7, clean the bearing sleeve and hub, and install the new bearing onto the hub to ensure proper installation.
Step 8, lubricate the bearings and bearing sleeves with lubricant, then follow the opposite steps to reinstall the wheel hub cover and tires onto the vehicle.
Step 9, lower the vehicle and check if the tires are balanced. If the tires are unbalanced, it may lead to unstable driving of the vehicle.
Finally, test drive the vehicle to ensure smooth driving after replacing the wheel hub bearings. Regularly checking the tightness of the nuts on the wheel hub bearings and conducting regular maintenance to extend the service life of the bearings and avoid wading in water is also the key to maintaining the normal operation of the bearings.
