Hey guys I went racing yesterday and on the third pass when I took off I heard a loud bang. I got off the track checked everything out and it looked fine. Went to run again and 4x4 wouldn't work. When I went to load on the trailer I put it in 4lo you can hear a clicking noise coming from the front. You can also crab the front drive shaft and it probably has 2" of play at the transfer case. Can any one help. Do you think its my front axle or transfer case? And you can hear the transfer case ingauge when I push the button.
