Not sure if its a steering tie rod end or a wheel bearing?

i have a 2000 jeep cherokee sport, when going down the road above 50 but below 60 i have a very bad vibration which the steering wheel wobbles alot and the front end of the jeep shakes like if i was to move the steering wheel side to side very fast. Also every time i turn the wheel any direction while moving i can hear clicking from the front.
