Loose Tie Rod

Tie rods are generally part of the steering system; i.e. the front suspension, rather than the rear. Does your Outback have 4-wheel steering? Some higher end performance vehicles have that function, but I wasn’t aware an Outback did. There are control rods, usually called “arms”, or “links”, for controlling the orientation of the rear wheels. So is this problem for the front, or or the rear of the vehicle?
