8. Extract the bearing from the hub using the extractor.

The hub double-row bearing does not need lubricating or regulating during the car operating life. When you extract the bearing it breaks down. For this reason, you should compress the hub if you only want to replace the bearing.

 

If you have no bearing driver or extractor which can help you to extract or compress the bearing you can use the rings of the old bearing.

 

9. Compress the new bearing with the extractor and set the check ring. Clean the components before installation to remove all dirt.
