i have a 2011 x5m

so past two weeks ive noticed that 50% of the time I start up and drive there is some vibration and rougher ride than normal. Don't think its rims and tires b/c they are all recently checked and the problem disappears sometimes completely

I am thinking its something either with xdrive being off or perhaps the suspension

car drives ok but feels less secure than normal. more bouncey in the rear, mor e vibration in the steering wheel and throughout the car. seems to take road bumps much harder esp from the rear. almost feels like there is a slight flat or bent rim when i am on perfectly smooth road. feel it at high and low speed though at low its less intense. again, thought it might be tire/wheel related but it goes away completely sometimes.

any thoughts??
