Default MP7.5 weird problem

This is my first Kyosho buggy, i've bought it use but in great shape.

I have run it today for the first time, and each time that i do some little cartwheel, the rear right drive shaft pop out of the diff outdrive.
So i've look at it closely and when i fully compress the rear suspension, the right rear drive shaft exit by about 1mm the outdrive, and the left one stay about 1mm in the outdrive

I realy don't know why the left and right side don't work the same way.
All the setup is the same on left and right.

Look like if the only way to solve it was to limit the shock travel by about 5mm.

Is somebody have ever had this trouble

Thank you!

David

OK i've take a look at the front and rear axle, the front is 90.7mm and the rear is 89.5mm.

Is this little difference could make the difference

I have solve the problem, i had my Ofna DM-1 laying aroud and i've take a front universal on it, and it was about 3 mm longer than my Kyosho one.
Put it one and all is very good.
