looking through the forums it seems you might be the guy who can answer my question. I've got a 2004 Ranger with live axle shift on the fly. My problems is after engaging in 4 low or 4 hi, it randomly disengages the FRONT differential at the transfer case. While up in the rpm's and it disengages it sounds Horrible. My problem had progressively gotten worse. Its at the point now i cant use 4x4 at all without the front diff disengaging. At a low rpm it sounds like is just slips right out of however its engaged inside the transfer case and makes a grinding/ gears slipping noise?? Any help would be really appreciated. Thanks -Ryan
