I have a 12 bolt Moser with the posi. For the past couple of months, when I go at WOT it always seems the car will pull a lot more to one side. Ever since it started doing this, I have been through two sets of rear tires, and for both of them the left tire was much more burned out than the right. Does that mean that my differential is toast? The rear end has under 2500 miles on it in the past 2 years. I haven't checked the oil in it, but I think it might have leaked out.I should of regularly checked it
What are some signs of a bad differential, and some signs that the rear is low on oil? I bought 2 quarts of 80w90 gear oil to put in tommorow after I check it.
