I have a 97 Exploder Sport with Control-trac. I have been having a grinding, moaning, vibration type noise. It sounds like it's coming from the left front (wheel bearing) but it feels like it coming from under my feet (drive shaft or transfer case). It only happens when under load and goes away when coasting. So I don't think it's a wheel bearing. However it also goes away when I turn left under load. It is driving me freaking NUTS. I have replaced: Upper & lower ball joints (both sides) New tires & wheel balance. Alignment So it is not any tire, balance, alignment or ball joint issue. My feeling is it is a front drive shaft or bearing in the transfer case. I want to try to eliminate the drive shaft as the potential problem. So my question is can I disconnect the drive shaft & drive it around without hurting anything? Does anyone have any ideas on what this problem is? I'm about ready to push this P.O.S off a cliff. HELP.
