Cause some of us don't have time to read every post. I DO use search as often as possible but did not last night. Thanks for your useless comment.
For the other questions. I'm not running synthetic and I did have sure grip additive in. Professional built my rear end, restores Mopars for a living. He's a member here, ShowAndGoResto, builds lots and knows his crap. Will have him check it out.
For the complainers of my thread, sorry to waste your previous time. I usually don't rebuttal to useless criticism but get a life. Add something productive or ignore the thread. Thanks.
