NEVER EVER try to save a bearing of this type.
1...You may warp the axle from the pressure, as you have to press on the "long" end
2...The splitter/ tool/ other device is likely to put so much pressure on the balls/ rollers that you will damage either the balls the races, or all three
This is one reason I hate the expensive and stupid newer design of front wheel bearings. It all first started with the Dodge "full time" 4x4s and other front wheel drive vehicles. Even my 01 Ram 3/4 2wd used the Damn things.
