Humming sound from the back over 50mph
Hello guys,
S40 07MY
I'm having humming sounds like a pump from the back. I've had this from the moment I own this pre-owned car. It's been 3 months I owned this. Odometer going over 75000 miles.
Here's description :
1. Usually starts to happen over 50mph
2. Sometimes, it's fine even though I reach up that speed.
3. Tested high speed slalom, the sound stays constant left or right.
4. Sounds like a pump. Doesn't have something to do with throttle level though.
5. When the vehicle slows down, it goes off
Is this normal for S40?
If it's not, what would be the culprit? Any help please

Thank you! I'll check it out. It seems to be both of wheel hubs, haha. Out at the same time.
