Rumble felt in Floor at Speed

[jor]

15 Forester, 74K miles

Normal when traveling straight at maybe 65mph on a freeway. Change lanes to the left and there is a kind of rumble I can feel in the floor. Kind of like when you pass over a rumble strip but not near as noticeable. Normal when changing lanes the other way.

I put it up on jack stands and didn't find any noticeable play in either the right or left wheel bearing. I was thinking maybe an axle but I don't hear any clicking when I drive at low speed and make a turn. Ideas? Thanks.

Answer my own question: It's the left axle. Did some tight turns in a parking lot and heard the clicking.
