Front Diff issues

So a while back I found that my yoke was loose on my from diff. I went ahead and changed and all the diff bearings and seals. when I took it apart then I noticed that the crush sleeve was no crushed and It seemed that was were the issue was. well I recently noticed that I have a all the sloppiness again. it doesn't make any noise unless it in 4wd and the front end is pulling. im not sure what could cause this a second time. has any one else came across any on this. :bang
