I was wondering if there is a video, or good manual on how to remove and replace the wheel bearings front and back on a 650l? When replacing the bearings, do the seals get reused, or buy new ones as well? I know to get a tool for the retainer on the rear. I know to get a bearing puller tool to get the bearings. That should get the rear done, correct? What special tools will be required for the front besides the bearing puller?
