My rear case has had some problem since I installes the duals. when I am shifting from 2hi into 4hi, the shifter sometimes gets stuck halfway. I then have to take it out and re do everything. has anyone ever had this happen? and what did you do to fix it? there are two shift rails in the t-case, one for 2/4wd and the other for hi/lo. it is getting wedged in between the two rails.
