first post on the site, what a huge audience that this reaches out to, I must say!
Anyways, my parents have recently purchased a WRX STI Sedan, 03 and lately we've been hearing some strange noises.
Noise number 1: A loud thudding noise as if something is banging around in the boot (which there isn't :P)
Noise number 2: Regularly cruising around and it sounds like we're driving a plane? Seems like the wheels are letting off some weird, sustained humming noise as if you're taking off in a plane - hope that makes sense lol..
Anyways, I followed up the loud banging noise with the previous owner and this is how the conversation went:
[Me] Hey bro, the car makes this strange loud bumpy sound. Back left wheel maybe? Like something is moving around in the boot or something but there's nothing. Any ideas?
[Him] ohh its not left side its the center back the anti slip diff they make noises under low speed its perfectly fine, i got it checked by jtune when i purchased the car
, they said its just a noisy diff, koz its anti slip.
Any ideas on what this could be, team?
Thanks in advance!
