Well...I replaced the front differential and I STILL HAVE A PROBLEM

It seems that the front differential failure was the result of whatever is wrong and not the problem itself! Here is the problem...often when I step on the gas, I will hear/feel a vibration under the car and the DSC/traction light will flash on until I take my foot off the gas. The CV/axles are fine...can this be a transfer case problem? The only other thing I can think of is the shaft that goes from the transfer case through the oil pan and to the passenger side shaft.

Any tips for diagnosing a bad transfer case? I will certainly check that little plastic motor that goes bad...but what else can I consider? I'm going in for some exploratory surgery but I wish I could just look in one place
