About 3months after buying 2008 Edge SEL FWD until present 2yrs later, noticed a "click" noise when turning the steering wheel.  Does not matter if I am stopped or slowly moving, left or right direction.   Turning steering wheel end to end click occurs maybe 3-5times.  At high speeds do not turn wheel far enough to notice. 
  
Have been to the dealer about 6times for this.  They hear/feel it to and have replaced all kinds of stuff including the rack & pinion.  Now we are onto replacing steering column parts in the next week or two. 
  
Anyone had anything similar?
