My X5 started vibrating badly since I hit large pot hole last week. I since replace the front wheel and balance align fronts wheels. Mechanic also notice worn CV boot therefore also change together but problem still there till finally last nite, loud bang on front left hand wheel while accelerating up hills then followed by continious metal clinking sound. Couldnt drive and stop the car on the slope. Clinking sound seems to appear when put in gear.

Does it sound like transfer case to u guys?

Cheers
