Problems with Chevy Joy 2001

This is my first theme in the forum The thing was like this
to my Chevy, the homocinetic joint side box was released, it was changed to a new one and thinking that it is already well correct it and zaz that it gets out of the denuevo say that the car opened for a blow and that it is necessary to close. How true this will be this?

If it opened as they say it would be noticed on the wheel, I have seen that happens, the pillar is loaded and the Avansa wheel carrying the inner homocineta and taking it out, you have to see that you have no problems with the tray.
