Hey guys, excuse the title haha couldn't help
But yeah it started awhile ago.... first from 70-80mph then slipping down to where it is now at 45 to about 60. It does it mostly when the tranny shifts into 4 lockup or even 3 lockup outta OD up till 60. The x-case shifter shakes like crazy when it does it and its loud too.... I'd read once about something in the x-case with the rear seal or bearing or something causing shakes around certain speeds similar to this... I've never gone into the t case or seen one apart so i dont know much about them. If anyone has had this happen or know of other solutions?? I doubt its the tires, no cupping or funky wear on them and at good pressure, good tires too not soft muds. Its drivin me CRAZY lol please help! Thanks,

1. u-joints on front shaft.

2. sometimes the big nut on yoke will be loose.
