You need to check the backplate of the compressor housing isn't worn, the oil seal sits in a hole in it, but if the shaft is wobbling its more than likely the backplate is worn (alloy) so that too will need replacing.

Also the cheap kits won't do you, as you have a 360 thrust, AND you need to check your shaft for signs of scoring.........if its scored u will need the shaft machining (if its not worn toooo bad) and oversize bearings....
