I'd caution you against replacing the bearings out of hand. The original bearings, if properly cared for, will last twice the life of the vehicle. They are very well made. Usually a thorough cleaning and repacking is all that is required.

The risk of a new bearing is reduced quality and a component that won't last as long as the old one. Not a definite thing..........but..........the risk is there.

Be very careful in pulling the inner seal. If you use a prybar, improperly, you will damage the inner bearing........which sits directly inboard of the seal.
