Ferrari potentialy facing critical issues?

This is only speculation!

When you connect Ferrari and Haas problems that they faced during Australian GP weekend it seems likely that the problem may be at the rear of both cars, which would mean that is structural and very serious.

Haas as an customer team takes rear suspension and gearbox casing from Ferrari. Altough Sauber, another Ferrari customer team, faced an issue in the race with their rear supsension, they design those things themselves and wouldn't be affected by the same issues, that's why I will leave them out of discussion.

In testing Ferrari had hydraulic problems on day 3, Bearman crashed in FP1 and then in quali he had gearbox issues, Lewis lost gear sync in the race. Those 3 things might be not connected to each other, testing is testing, Bearman's gearbox issue was most likely related to the crash and Lewis gear sync wasn't anything serious. But lets look at the darker scenario.

What if Ferrari raised the ride height to protect the gearbox? The rear of the car was completely redesigned and maybe something went wrong there? Some people say plank wear was the reason for raising the RH but it doesn't make sense when you expect a wet race.

On top of that, Ferrari lost lots of performance after raising the car reportedly by only millimeters, which indicates very narrow working window.

Obviously this scenario is the worst possible one and doesn't have to be true at all. Haas issues might not be related to us in any way and the problems we had might have just been as simple as miscalculating our setup choices. Remember that Charles said that they had to make compromises only for last weekend.

Whatever issues we are facing, let's just hope that we can resolve them quickly.
