Guys I need a little help. I have a 2004 V-8 4runner AWD and recently lost a transfer case (No oil in the old case was the issue. I must have bought it like that because I did not have any oil in the driveway or underneath the vehicle that had leaked) and had to replace with a good used unit from a company called LKQ. I installed the new to me used transfer case and tried the unit while it is on the Jack stands. I am only getting output from the rear of the Transfer Case. Left rear wheel is the only thing turning. I tried switching from 4hi to 4 low and still nothing. I did notice I had a VSC off and VSC Trac light on. I tried differential lock button. Still nothing. I can hear the Actuator working when I try to switch from 4hi to 4lo or from 4lo to 4hi but do not have any movement from the front output shaft of the Transfer Case. Can anybody get me pointed in the right direction as to what might be the problem?
