I have a 06 Outback. Rattle in left front started 3 mos. after I bought the car. Noise sounds like a large can with bolts rolling around in it. Can only hear the noise when driving on a rough dirt road (not on pavement). Had it check out several times. Finally, they replace the front strut. Noise returned in a few days. Seems everytime the car is jacked up the noise goes away for a few days. Also if I depress the brake slightly as I am driving the noise stops completely! Can't get the dealers to return my calls. Warranty is up in April. Any suggestions??
