Hello, i have a 2002 x5 with 3.0 140K i had a slight whistle on slow acceleration (couldn't hear it when driving) sheduled to get it checked out. then on light turning start from stop, a snap sound and nothing but a high whistle. vehicle was immoble. although i could push in N but starting makes whistle sound! eek. i lifted it with all 4 wheels off the ground, fronts roll in opposite direction with emergency on, rears roll in opposite directions and make fronts move. all shafts seem to be attached and tight at their joints,
i was thinking transfer case but the write ups ive found seem like i shouldnt get transfer from front to rear?
help. i looked in my vis software but couldnt find any test to do other than a DIS (software maybe) test
getting all four wheels up was worse than changing out the crankcase ventilation system!!!!
