Hi, I recently became the owner of a 1974 914 1.8. The car has been checked over by a UK Porsche specialist and been found to be mechanically sound but there is an intermittent strange whirring/rubbing noise that comes from the rear.
I say intermittent as the noise only appears after 20 mins or so of driving and stops when driving under 25mph and returns again when driven over 30mph. The noise doesn't get any worse with speed, in fact it appears to get better but that maybe due to being drowned out. The mechanic could find nothing wrong. Does anybody have an idea of what could be wrong or how to identify the problem? Many thanks. |

Is it a high pitch sound? I have a similar problem on mine and wondering what it is as well. High pitch sound, only happens after driving longer distances, not from just around town, it seems. High pitch sound, from the rear, not able to tell which side of car, and hard to detect at all except if driving alongside a wall or some other structure that reflects the sound back. No vibration or anything.

No vibration or anything. It's definately a high pitch sound. Kind of like your kids squeeky wagon wheel. It starts making the noise after about 5 miles of driving and you have to be going faster than about 20mph. Just past 20mph it starts and pretty much sounds the same at 70mph. Take it out of gear at 70mph and coast all the way down to 15 or 20mph before it stops. I've done all the swerving back and forth, coasting out of gear, shutting the engine off at 50mph and coasting and it doesn't change the sound. It is definately not coming from the tires or anything related to the brakes. It's got to be the rear wheel bearing. |
