Well, I'm trying to chase down a phantom vibration in the front end. There's a very noticeable pulsation / vibration at low speed. The vibration seems to get less noticeable at highway speed, but the pulsing noise gets faster. I've tried swapping both the stock wheels (195/50/16) and my just repaired 5zigens (205/40/16) from back to the front on the drivers side. The noise and vibration seems to be coming from there. I'm going to do the same tomorrow on the passenger side. I noticed that the car was making some noise, which I thought was because the tires were near the end of their usable life... Any ideas? I'm thinking it could be a bearing... Not sure, as I can't detect any play in the drivers side wheel at all. I have yet to investigate the passenger side, but since the noise seemed to be coming from the drivers side I checked there first. I lost my patience with it and garaged the car for the night. Any ideas or suggestions would be appreciated.
