Hello every body ... im new here and this is my first post here

so my problem is really weird that when im drifting with my mst xxx-d vip every thing is OK until I pull the throttle to the end (top speed) and turn to the right (only when turning right and full throttle)

The right wheel stop runing like the car is only 3 wheel drive . Its not stuck but dosnt conect with the diff ...

BTW I checked the diff and every single thing is really fine and super fine and its new and just start acting like this after a month before that every thing was normal 4WD and the diff is alum one way

and also its come back again 4wd after I totally stop the car and start over its start as 4WD but only when i go top speed with right turn thats happen ...

so dose any one had the same problem ?!!! Please I need help
