Sometimes I hear a pretty loud "pinging" sound coming from the back under the car after turning a street corner at slow or moderate speed. This pinging sound is accompagnied by a noticable twiching from the back like if something wanted to jam... Then after, everything goes back to normal. It only does this from time to time and not at every street corner. I fear this could be the diff's carrier pin wanting to come out. Any idea as to what could be causing this? I have a Detroit locker installed by the way...
