hello, i have vibration in the steering at 50mph and up-went in and had tires checked, balanced, etc. no help-was told it was the inner tie rod and not dangerous to drive on, but needed fixing. went to another place, they said they'd fix it for $170 and i'd need another $50 for an alignment--does this sound reasonable? also they said it IS dangerous and the wheel could fall off--true? we're s'pose to get another hurricane this weekend and i don't really want to spend 2 hours waiting to get it fixed at this time. Thanks!!
