Too much grease will make the balls slip, and to be honest, a little grittyness won't harm performance.

Tamiya AW grease is best for the thrust bearings, pack it good. It's so thick it doesn't let much else contaminate it and make it gritty for a long time.
The key is break-in.. don't wrench it in right away, tighten it enough to get the diff action, use a dremel, drill, drill press, whatever with a flat-head screwdriver bit to run it for 30 secs, check the slip and tighten a quarter or half turn each time accordingly. It may take 5-6 mins to get it to the point where it no longer loosens up on you, but this makes sure the balls and spring are seated nicely, and leaves no surprises when you put it in the car and go for a few runs. My diffs have been through 4 races now without a rebuild nor grittiness. Then again, I have the wide-pitch pulleys that cover up the diffs ends. They're awesome just for that reason.

So don't sweat it thinking your not building them right, or using the right grease, or not using enough grease. Its not you...I've tried it all, more grease, less grease, different brands of grease, different thickness of grease, new TA05 balls, etc....it don't matter.
The only way I've gotten the diffs to stay smooth on this car is to get new balls, and replace the diff rings with Yokomo diff rings.
Using the stock rings with the stock balls, I see no way to keep the diffs smooth for any length of time.
So since you already have new carbide balls, pick up some Yokomo diff rings and you should be all good.

Not off the top of my head. I would have to search around to find out. I got lucky, I had some extra new in package rings sitting around from my Yokomo 4wd buggy, so I didn't have to buy any.
I'll look around on Yokomo's website and see if I can find the part number. It shouldn't be too tough to find since they're just stock MR4TC/BD diff rings.

On a side note Ive ran this car for 3 weeks and not a single part has broken on the car.
The Penquin chassis has worked really well for me. This is the best handling car Ive owned (Pro4, RDX). Im 2 laps better then I was with the RDX and the car is just so smooth.

The only downside to the Yok rings is that they're hard to find because Yokomo uses them on pretty much ALL their cars that have a ball diff. And then there's people like me and Core Creations who use them on our non-Yokomo TA05 cars, so supply struggles to meet demand. Right now, speedtech and stormer are both out of stock.
The best way to get ahold of them is probably to order them through the local hobby shop and just wait for them to come in.
