Can't fix that. Your universal joints are not designed to operate at that angle, you need a dual cardon joint of some sort or less steering angle... and as it's a drift car that's not an option to just run less steering angle.

If it makes you feel better, the car was doing it before you just couldn't see it.

Your axle joints are binding. You can try double cardan style axles, commonly known as ECS or DCJ in the R/C world. However, with the steering extremes you're looking for I'm not sure those will completely cure the issue.

Edit: DR beat me to the punch

Nothing you can do about that. I think people call it "chatter"

The only thing you can do is buy aftermarket joints (called DCJ's) if they even have it for your car.

These are an example of what you'd be looking for. Notice where the joints come together, there's a piece in between. That coupling will allow better angles and prevent the chatter. Unfortunately, that's the only way to fix it.

Even when you ran a front diff the axle bound with each revolution, but the diff action smoothed it out and you it didnt hear it actually make noise. Standard joints are no good for that massive steering angle.

A spool makes it worse. It happens even when you use a diff, but it's just not nearly as noticeable.

Again, nothing you can really do to stop it except buy after market parts for your car. I don't even know if they make ones that small.

So the last decision now is ECS or DCJ

but additional question
what is the difference between them ?!

ECS = DCJ

Xray calls ECS for "Equalized Corner Steering" but they're the exact same things as DCJ "Double/Dual Cardan Joints"

xray names parts in their own, special, "luxurious" way.
