100cst to clean Diff
I would like to elavorate a little bit on JPZ 67 coments, the 100cst shock oil which is aprox 8wt on standard weights works really good, it will thin out the oil that is left in the diff. Pour the 100cst shock oil in the diff cup with the gears in it, hold the gears in place, rotate, then use low press air to blow all the oil out, repeat these steps two or three time as required. (don't forget to point the cup away from you or cover with rag or paper towel.) You will be amazed how well this works and the best part is that you do not contaminate the diffs with foreign fluids. Using solvents, degreasers, or other type of cleaners won't always be completely flushed, you would have to flush the diff with diff oil several times which will waste your Precious fluids.
