ok, a couple quick questions for you all 1. The wheel bearing thing, I listened more closely and I think the buzzing noise is coming from the rear left, right behind the driver. any answers? I just changed the sparkplugs and gas line recently. Could I have messed something up around there? 2. when I reach 65MPH or so my windshield starts to vibrate near the top by the driver. anybody have the same thing? anybody know what to do about it? I don't know if it IS the windshield, but its coming from that area. Erik Geerdink
