I own a 2001 outback and recently i started hearing what sounded like wheel bearing noise coming from the left front wheel. The noise increases with speed. I lifted the car up and checked for vertical play (top to bottom) but their was no play instead the play was side-to-side even though i replaced the inner tie rod a year ago. What could be causing the noise if there is no vertical play? Has anyone experienced such a contradicting event, and if so what did it end being? Thanks
