on my way home today, started getting bad vibes, got off highway when starting to exelerate it started again, then got worse. dropped my driveshaft when i got home, u joint going to yoke was very stiff, took it out and it seemed to move freely again, is the driveshaft supposed to have any play at the t-case, it wiggled a little, slightplay but not that bad. checked suspension all is tight. 350/350/208 4 inch lift 35's any ideas? the u joint did not move too freely when it was on the drive shaft, but after i pounded it out it seemed fine, grease in it and not much wear.,
