Deconstructing LNE IMS Installation Failure

[dagdisco03]

Do you have any pictures of what you are describing? Something sounds way off here. Press fit post? The LNE tools come with a thing that would allow you to remove the bearing with a broken center stud by pushing the stud into the IMS shaft and then sliding this thing in through the open hole and feeding a stud in to attach the extractor. To insert the the bearing you should be only touching the outer race of the bearing to hammer it in. The center stud should have the nut put on hand tight to keep it from falling into the IMS shaft as you are tapping the outer race in. It's not used for the install in any other way. I have nothing to do with LNE but I did this project last year and can't figure out what you were doing from what you posted.
