Anyone else? Any suggestions?

I threw in a new set of gears and we'll see how things look after this weekend
I've had this happen in 2 diffs now. Very strange. Mine are tki3 diffs, not from a spec A

Yep it has been happening ever since the MP9 was released. To get around this I put a little thin tyre glue on the inside of the diff case around the centre bushing spreading it evenly as possible over the plastic to the size of the side gear and just enough so it has a smooth surface. Sit it flat somewhere for at least 20 min to dry, clean any excess then assemble diff.

After a few you will be a pro, not getting any in the oring groove, building up to the right level, etc. I have done this for years now and it does help a lot.

You can also remove material from the gasket surface but I was worried about it being uneven afterwards so I use the above method. Another added bonus is the diff casing lasts longer before it develops a oil leak around the centre bushing.

what about if you used a very thin shim? would that also work?

so based on what your saying by putting a thin layer of glue on the diff case at the bottom where the ring gear sits on lifts it up slightly to give a more compact gear meshing of all the gears once the diff is assembled?

Yes thats correct. I tried a thin shim but it distorts and damages the oring.

you gotta be kidding? you have to gerry rig a $900 car? so much for the quality of this thing. I just bought one and now am thinking i will probably be better off returning it.

Haven't had this issue yet myself and my car has been run hard for 5-6 gallons now. My guess is there is bad batch of gears out there. The Kyosho drive train is about as good as it gets.

what is Kyosho doing about this via warranty services? are they stepping up and taking care of the customer if they have these issues?

Listen, it is $900 car because it is the best. I have never had this issue and I have 4 TKI3's between my son and I. 2 Nitro and 2 E's... Sure, there will be some issues here and there for some people but don't run off to another brand who I promise will have WAY more issues than this. Plus, after you buy al the upgrades you will need, you would have wished you would have just stuck with the best buggy out of the box.

I heard these cars have all the yum-yum and upgrading is not needed but now I am reading you have to gerry rig the diff case, bad batches of diff gears, boil the a-arms and that is only from reading the last 2 pages

All I am saying is that I nor anyone I personally know has ever "Boiled A-Arms", had diff case issues or bad gears. In fact, Kyosho is known for it's drive train. The diff don't leak like others and just plain works...

But, you have to believe in what you drive. If you have doubt in the product, then by all means switch. I am just trying to share that you will always hear stuff (Not that it is not true), but that does not mean it is the norm.

I am getting a little lazy in replacing my fluids in the diff cases. How often would you say these fluids need to be replaced. The car will be in normal wear and tear.

Their are no problem with the diffs my friend. You can ask any of the local racers I race with....if their was a problem with diffs I would be the first to break them. . I have countless races without even touching the car......run it till it breaks.
