I changed fluid a few days ago and used the following:
4874469 Mopar syn Diff Fluid, 2 qts
4318060AB 4 oz frict modifier

Before the fluid was changed, the rear worked 100%. After running at Atco Raceway today, only two days and 50 miles later, I have a problem. I am in the option it is the fluid. The problem is on turns now the rear is starting to lock like the posi is not working correctly. I jacked up the rear at the track thinking it was the rear, my Unitrax half shafts or the like, but I don't think so. I drove 20 miles home and it ran good, but on turns it is binding slightly, and anyhow can someone please confirm my fluid? I KNOW the wrong fluid can do this crap as I have seen it on other cars in my life and hope that is my problem. Anyhow, thanks in advance and if I need a rear, I will stick with a stock ratio, but my gut is saying I have the wrong fluid in there. Thanks, Gary
