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 ??
