KIGO254

The noise seems to increase in intensity over time,4 weeks ago it was barely audible.Now it can be heard even when the radio is on .Vibration is felt on the floor. At neutral the noise is still present, but I have not tried disabling the AWD using the spare fuse.

The problem was present before the tire change since i suspected the tires were the cause of the problem.On tight turns the noise is still present.Will inspect the u-joints, carrier bearing and axles soon as i have some free time.

i replaced the tires two months ago and they are similar in every aspect,bakes are okay.Noticed previous owner had one disimilar tire.

I recently bought a used 2004 Auto subaru legacy Bp5 about 3 months ago. However, I have been hearing a pulsating whummmmm whummmmm whummmm noise but ONLY when i hit 60kph. The noise is also a vibration that i can feel through the gas pedal and the floor. It pulsates and is not a constant noise like a bad wheel bearing. Also, the noise increases its frequency as the speed increases. Anyways, I have taken it to several mechanics and neither could figure out what the noise was because it only happens under load. One mechanic said it was probably my differential starting to fail. The other said it could be a lot of things and that i would just have to let it get worse. I can't wait.....its annoying and I dont want it to get worse and cause any more problems. The noise doesnt change when i turn, as long as i am going above 60kph, the noise is there. the noise also increases with speed, or pulsates faster when i speed up, slower when i slow down,even in neutral. Any ideas???? I would really appreciate any input. Thanks!
