Where is the DIY for changing diff fluid

Changing differential fluid
On most of these questions about changing the differential fluid, I keep seeing instructions to refill the differential with fluid until it runs out of the hole. In my manual it says, on 9.25 axles, to fill the unit to within 5/8" of the hole. I have seen a TSB where possible damage can be caused to the axles due to over filling the differential. The problem arises when the fluid, when overfilled, can foam within the axles causing improper lubrication resulting in axle failure.

A small 4oz bottle is what the manual specifies.
Don't forget to do several large figure of 8 turns so the additive gets well mixed up with the diff fluid.
I have a DTT and don't need this stuff now lol.
As for service interval, it's 15 thousand miles for the front and rear diffs on a 4x4.
These Dodges sure are heavy on the services, but I guess it's to "catch" those clutch pack retaining clips.
