Hello everyone I have a 14 wrx sedan and have recently noticed a oscillating or pulsing hum comming from the right side under the passenger seat. it starts humming around 50-60+ mph on the highway.
I've researched alot of info but was trying to make sure. Heard it could be the rear diff or wheel bearing?
Can any one pleeaaase help me, my car is still a baby and don't wanna replace parts alrdy :/
