Front suspension making clicking noise at freeway speeds.

www.repairpal.com/repair-shops Use that link to find a different shop near you. Clearly something is wrong -- seems like you may need a new set of eyes on your vehicle. Of course we can't do much from here, other than theorize. I would expect possible axle concerns causing clicking, or front steering and suspension concerns causing noise and loss of vehicle control over bumps. This is a dangerous situation and should be checked before driving further, as you can injure yourself or others in an accident.
