Oh yeah they will wobble.Easy test is lift the wheel and grab the wheel at top and bottom.If it moves they are bad kind of like a bad ball joint.They do make a tool to do them on the car but Ive never used them.That and when you get them that old they are tough to press out most times.Advanced here has the good bearings and usually the hub itself is also bad.I used to do a lot of those a few years ago.Unless you have a good press and some stout pieces to set it up a shop usually is best to have them pressed.Rocky
