X5 vibration / shuttering during hard acceleration only, help!
 

have problem with shudder / vibration under harder acceleration it feels on car body, floor, pedals, more from engine side , which increase as it gets closer to shifting gear ~2500-3000rpm, especially going up a hill. Its not matter engine is cold or war, not matter on what speed going,


changed:

* engine, tranny mounts (after changed tranny mount it was dissapearded for short period)
* front both axle shafts
* driveshafts flex disc joint Guibo + center support Bearing
* fluid in transfer case and transsmission.

any ideas ??

Control arms?
Bad belt in a tire?
Missing hubcentric rings?
Steering racks Torque converter?
Transmission or torque converter dying?

Not sure what year your X5 is but if it is an early non XDrive, my guess would be the transfer case chain is stretched and slipping.
