I'm a noob to working with cars so I apologies in advance for the vague question, I'm looking for some support in identifying the problem I'm hearing rear of the car - it might be a common fault although I can't find other examples on the forum.
The noise sounds rotation related, not a clunk, more of a fizz, only noticeable either at speed 70 mph+, or accelerating while cornering. Haven't managed to identify which side it is yet - Does this suggest it's suspension related?
I recently changed the rear disks and pads - is this a sign of me having done something wrong?
I can look at recording the sound, although it's not very loud.
Any advise on where to start with the fault finding exercise would be great.
