yoke change 489 case w/o disassembling

If you know the "feel" you can do it with an impact. If the dimensions are even slightly different from the new to the old, thread counts won't tell you squat. I've even added a very thin shim to reuse a crush sleeve before. You'll know if the sleeve has been over crushed because the bearings will get tight before you ever put any real torque on the nut. Crush sleeves do have a certain amount of spring to them.
