car   Differential Unit problem 1
Failure Date: 12/10/2013

This is the second Ranger I have owned that has had this problem. The gears in the rear differential are grinding and the pins are loose. I had shop take off rear diff cover and they verified metal shavings/shards in oil and loose differential pins. If the pins/gears lock up the rear wheels could lock up and cause wreck. There is a recall for the this issue for manual transmission model Rangers but not auto transmission models. Look at carcomplaints. Com and you will see others who have same issue with auto trans models (I am sure other sources have same complaints). Looks like same parts were used in both models but only one was recalled.
