all thats good. still havent taken apart the tranny or rear end yet. gonna do the rear end first. the reason im narrowing it down to the rear end, is because i drove it with only a front driveline and there was no noise at all. i cant remember what its called off the top of my head but that rubber piece between the crossmember and the t-case... seems like its going bad. it as cracks in it and is pretty loose. could this be causing the tranny to move enough to be hitting the cab?
