Ive noticed lately that my LSD has been giving out lately. An example is when trying to bust some nuts while already turning with a clutch kick its a big one tire fire. But, If Im completely stopped and break them loose in a straight line its both tires. (tested this in the rain last night)

It seemed to have gotten worse since I changed the diff fluid to the ford 80w90 with the friction modifier. Whats something else I could put in there to help it lock up again like it used to be? Or am I just stuck with pulling the diff and re-shimming the clutch's?

Could just be the diff is tired and needs a rebuild. Trying putting some regular old 75w90 oil with no friction modifier in it.
