1988 Differential
I changed my diff oil last fall before hibernation. I added an 8 oz bottle of additive and filled to the overflow point.
Question is, how does one know if the diff is working correctlly or if there is enough additive? I did notice this year that when cornering or blasting flat out I do get some rear end sideways slide. It doesn't seem stable especially on power cornering. Could this be due to the diff clutches not working right?
What is the indication of incorrect diff operation? Chattering?
Appreciate any observations.

If the "additive" was the GM posi traction fluid, or equivalent, you added the the correct stuff. Eight ounces is enough.
RACE ON!!!
