I am new to this site and I have a question about my np 203 t-case. 1. How do I tell if it is full time or a part time. 2. When i am driving down the road and I put my hand on the shifter and I let up on the gas I can feel a clunk in the shifter. Can somebody tell me what the clunk noise is. first I thought it was the u joints but I changed them and it is still there.
