ok so I know a lil bit of detail since I read almost every page on here about all possible cause of issue but wana double check now.
so I think I need a new tcase the front drive shaft moves a lot I can grab it and turn it prolly an 1/8th to a 1/4 inch back and forth and when I do so I can hear a ticking noise as I do so if I do it hard enough to make the same fast passed motion as if I was driving. now when I drive it sounds like an angry clocking (that's what I call it) ticking like crazy till im going fast enough to not hear it. when I engage it hi low any thing but 2wd it makes a horrible hammer like sound when engaged and jurks a lil when I hit the gas as it slams. so like I said I know the tcase is prolly shot and im gonna replace it with a used one but just wana double triple check before I go buy one
