I have about 5000miles on my 04 STi and have been noticing this sound at only ~65mph; give or take 1-2mph.. happens on 5 or 6th gear. To be precise.. the sound is exactly like having a glass cup of water and making that "whoaa" sound by touching the tip of the cup in a circle manner. The sound is very noticable from the driver seat.. and not that noticable from the passenger side.. could this problem be that my wheel bearings are shot?? I did recently bend a bbs wheel hitting a pot hole pretty damn hard. ; ;

Also, i hear a knuckle sound coming from my front suspension when I leave my apartment complex after hitting a speed bump. This only happens when i barely start driving my car each day. Anybody else noticing this problem?? May I have just f*cked my front suspension?

wrong forum...but ill let you know that i do have a similar sound. i have it at 35 and 65. i noticed it after i got my car fixed from breaking a rear axle, so ive just assumed that was the problem. dont know what it is, though.
