I am experiencing a front end issue with my 77K mile Forester. I get a front end vibration noise at 20-30 mph on paved-but-rough roads, and have recently noticed that the suspension pulls a bit to the right when I hit a bump with the right front tire at freeway speeds. Am suspecting potential issues with RF tire lug, strut tower, sway-bar links. Hypotheses and ideas for testing are appreciated!
