Dana 35 Posi - additive?

Just did a 200,000 mile flush on my Posi Dana35 rear...Is there an additive that should be added to the new fluid?

A D35 with trac-loc is supposed to have the appropriate "friction modifier" added . You can get this at the dealer among other places. However, if the thing has 200 k original miles on it I doubt there is any friction (between the clutches) to modify.

It is so worn out at this point you don't need any additive.

This is the second flush, with the first one @ 100,000k , very clean inside, hardly any specks of metal...This rear axle, never gave a lick of trouble, probably the best component on this 34 year old Jeep....Many more miles to go.....
