輪轂軸承維持著汽車行駛的重任，承擔著降低底盤運轉時的摩擦阻力，日常維護肯定是必不可少的，下面
濟南哪里修奧迪比較專業廠家來講講汽車的輪轂軸承在拆卸時的正確步驟！
The wheel hub bearing maintains the heavy task of driving the car, and is responsible for reducing the friction resistance when the chassis is running. Daily maintenance must be essential. Next, where to repair Audi in Jinan, a professional manufacturer, will talk about the correct steps for removing the wheel hub bearing of the car!
1、拆下輪轂軸頭的裝飾蓋、防塵罩；
1. Remove the decorative cover and dust cover of the hub shaft head;
2、拆下輪胎但不要碰傷輪胎螺栓的螺紋，如果是盤式制動器，應拆下制動器，再用工具拆下鎖圈或鎖銷。
2. Remove the tire without damaging the thread of the tire bolt. If it is a disc brake, remove the brake, and then remove the lock ring or lock pin with a tool.
3、使用專用的工具拆下輪轂軸承；
3. Use special tools to remove the hub bearing;
4、清理舊的潤滑脂，并使用清潔劑清洗然后用抹布擦干，后用布擦凈軸承內腔。
4. Clean the old grease, clean it with detergent, dry it with a rag, and then clean the bearing cavity with a cloth.
5、檢查輪轂軸承與軸承座圈，發現有裂紋、疲勞剝落和軸承滾子松散等現象，應更換軸承。如果發現軸承座圈上有麻點，也應更換軸承。
5. Check the hub bearing and bearing race. If cracks, fatigue peeling and loose bearing rollers are found, replace the bearing. If any pitting is found on the bearing race, the bearing should also be replaced.
6、檢查軸承內徑與軸頸的配合情況，配合間隙應不大于0.10mm測量軸頸時，應在垂直地面的上下兩個部位（該處為大的磨損部位）測量。如果配合間隙超過規定的使用限度，應更換軸承，使之恢復正常的配合間隙。不允許在軸頸上打毛刺、麻點來縮小間隙。
6. Check the fit between the bearing inner diameter and the journal. The fit clearance should not be greater than 0.10mm. When measuring the journal, it should be measured at the upper and lower parts of the vertical ground (this is a large wear part). If the fit clearance exceeds the specified service limit, replace the bearing to restore the normal fit clearance. Burrs and pits are not allowed on the journal to reduce the clearance.
7、待所有零件都符合要求后，就能將涂有潤滑脂的內軸放入到輪轂中。
7. After all parts meet the requirements, the inner shaft coated with grease can be put into the hub.
8、在涂抹潤滑脂的時候也要注意，涂抹的量也有要求，它需要你從軸承一端涂抹到軸承的另一邊，直到它冒出來為止，不過，腔內不要涂抹太多。
8. Pay attention to the amount of grease when applying it. It requires you to apply it from one end of the bearing to the other until it emerges. However, do not apply too much grease in the cavity.
9、把輪轂和外軸都重新裝到軸徑上面，用手將軸頭調整螺母擰上，然后用軸頭扳手按規定扭力擰緊調整螺母。擰緊螺母后，應左右轉動輪轂幾圈，看看軸承安裝情況；另一方面，通過轉動使軸承與座圈正確配合。此時軸承緊度適當，車輪自由轉動而感覺不出軸向間隙。
9. Reinstall the hub and the outer shaft onto the shaft diameter, screw on the shaft head adjusting nut by hand, and then use the shaft head wrench to tighten the adjusting nut according to the specified torque. After tightening the nut, rotate the hub left and right for several turns to check the installation of the bearing; On the other hand, rotate to make the bearing fit correctly with the race. At this time, the bearing tightness is appropriate, and the wheel rotates freely without axial clearance.
10、后依次安裝鎖片、固定螺母、輪胎、防塵罩和裝飾蓋等零件。
10. After that, install lock plate, fixing nut, tire, dust cover, decorative cover and other parts in turn.
11、輪轂軸承調整好后，行駛一段里程（10km左右），停車檢查，用手拭摸輪轂的溫度，如果發熱，為軸承調整過緊所致，應重新調整，適當放松軸承緊度。
11. After the wheel hub bearing is adjusted, drive for a certain mileage (about 10km), stop to check, and touch the temperature of the wheel hub with your hand. If the heating is caused by the too tight adjustment of the bearing, readjust it, and properly loosen the bearing tightness.
In addition, car maintenance is a continuous task, and good maintenance at ordinary times plays a great role in safe driving, so the majority of car owners should pay more attention to the daily maintenance of cars! More relevant content will come to our website http://www.cnjqf.com Consult!
