More then likely this is one of two things. First the bearing that you installed is defective or the CV axle is not fully installed.
Take a look at this material and if you find the axle is installed correctly I would suspect the bearings are the issue. I assume this is happening when you are moving and not just changing gears. If it is just during changing gears then I would think the axle is the issue.
I attached below the replacement process for the bearings. Let us know if you have other questions. Thanks
