I use Mugen grease sparingly. Just put the balls with a layer of grease will do. Like crash mentioned, the AE stealth lube is also fine. I guess graphite grease would be fine but I do not recommend silicone oil as it is not meant for the purpose.
Assuming you got everything correct, make sure that you tighten the E18 screw (M4 x 8) in step 2.4. Grab and lock the two sides of the diff shafts by using 2 screw drivers like in the picture below that I borrowed from Julius' article on the FPS diff. Try to turn the diff pulley and make sure it does NOT slip.
If that is done, try turning the two sides of the diff axle in opposite directions to check the diff tension / friction. The diff should be set as loose as possible. To make sure the diff friction is loose, you need to loosen the E18 screw (M4 x 8) little by little and always checking the diff pulley slip like described above and in the picture. The diff pulley should NOT slip and at the same time the diff friction needs to be set as loose as possible.
After you've gotten the right setting, lock the H16 set screw (M4 x 4) on the opposite site of the diff axle to lock the initial settings as per step 2.5.
Once this is done, the diff friction collar is assembled. That would be the one which would be controlling the overall rear diff friction via the single F12 (M3 x 10) cap screw as per step 2.6.
