On my 1971 914-6 when I reach about 15 mph I begin to hear a high pitch EEEEE sound about every half second. It sounds the same at 70 mph as it does at 20 mph. I can take it out of gear and coast and it doesn't change. I can hear the EEEEE sound every half second while coasting in neutral at 70 mph and it continues until the car slows down to about 15 MPH and then it goes away. It seems to be coming from my right front wheel area. Hitting the brakes doesn't change it at all. Swerving back and forth doesn't change it either. I removed the wheel and the pads are not touching the brake rotor. I spin the wheel and it doesn't make any noise at all. Any ideas?

The high pitch squeal sound has been cured, so I thought I would document the fix.
The annoying sound was coming from the right side of my 914-6. It would begin at around 15 or 20 mph and continue at all higher speeds. The pitch of the sound and the rhythm would not change weather it was 20mph or 70mph. The sound didn't change going around a turn, coasting in neutral or slamming on the brakes. I eventually determined the sound was coming from the right rear wheel area. I took the car to Vortex Motorsports a couple of weeks ago. They put it up on a lift, started the engine, put it in gear and listened to the right rear wheel bearing with a stethoscope and he said it sounds fine. He checked for anything that might be rubbing and even adjusted the emergency brake cable. When I drove away, the sound was still there. I took the car back yesterday and told them to change the right rear wheel bearing and guess what? That fixed the problem. This problem was certainly not your typical symptom of a bad bearing. The wheel was not loose on the hub, there were no grinding or knocking sounds. Only a high pitch squealing sound about every quarter second. |
