Hi everyone. I have a 2003 Porsche Boxster 986 base model. Yes, I bought a used older German sports car… I know. It is a fun car, it really is, but does need help from time to time… and I’m learning a lot about car repairs and maintenance in the process! I’m thinking about bringing it to a local indy for diagnosis, but I was hoping the internet could maybe give me an opinion first.
So, the car is making a high pitched sound that seems to be coming from the rear wheel. I can hear it when driving above 25mph or so - it reverberates off of walls and is less pronounced but still audible at speed without a wall present. It’s pretty steady when moving about 25 or above, but seems to go away below that speed and it seems to be consistent in tone regardless of speed (above 25). I’m guessing it’s a wheel bearing, but maybe you can help confirm my suspicion or have some other ideas?
I jacked the car up and checked for play in the rear wheels and didn’t find anything. I also rotated the wheels and they seemed to rotate smoothly with only a little friction from the brake calipers (which I believe is normal). It doesn’t sound like the typical bad bearing sound which seems to be more of a growl.
Here’s a link to the sound if this board allows such things:
Appreciate any suggestions. Thanks so much!
