I am surprised when I look from the back of my X, it seems to me the right side is lower. I asked my wife to double-check, she said it IS slightly imbalanced.
Then I start the car, drive it, no problem at all, everything looks balanced.
I stop the car and re-examine again. it is okay too.
The next day, I examine it again, the right side is again lower.
Do you know what's wrong with it?
