Hi, I'm new on this forum and I just got my 4x4 working that was broken when I bought my 89 xlt Bronco. I replaced the shifter motor on the transfer case, and I'm pretty sure the previous owner haven't used the 4x4 in a loong time. When I run i 4x4 mode, the car runs fine until I make a sharp turn and it feels like the inner wheel is shipping. It is like driving without a differential, and when I shift back to 2 wheel drive, the problem remains for a few turns until it goes back to normal again. Could it be the front diff that is bad becouse it haven't been used for a long time?
