RE: [Chevelle-List] Driveline vibes, baaaad vibes.

Rich,   I'm keen to see the article. U-joints are new and we've had them apart three times. In fact, I've got the car sitting on the alignment hoist of a friends garage right now with the driveshaft out and on it's way to CCI to make sure it's true & perfectly balanced. They built it, BTW, and insisted I replace the pinion flange. No change when the flange went in except the car was lighter by $200...   Why as a spectator? If I can get this car squared away, I'm going down there Wednesday night - much nicer cruise than the Tokyo subway conditions on Saturday.

Craig, I read in CAR CRAFT one time that this can be caused by the clutch. I'll try and find the article. Have you checked the U joints? May have a cracked one. I'll be at the cruise, but as a spectator this year. :o( Rich "66 Malibu ACES # 5066           ----- Original Message ----- From: Craig A.

I have what feels like a driveline vibration that comes in about 45 miles per hour and increases in intensity until about 65 MPH when you're actually going so fast that the frequency becomes so rapid it seems to go away. I don't think it actually goes away, just feels not-so-bad, if you know what I mean. It is not engine RPM related - it occurs in second, third or fourth at the same speed and continues if you disengage the clutch and put the trans in neutral. So, it is not engine balance related. I have new Moser axles, US Gear ring & pinion (3.42), new posi clutch pack, new pinion flange, new driveshaft and it has done the exact same thing with two completely different sets of tires and wheels. Also, it is not in the front end. I'm really at a loss here - the Detroit Dreamcruise is spooling up to max output right now and I can't motor down the highway. (By the way, the cruising is so heavy every night this week that the police will shut Woodward Avenue down on some nights. On Saturday, you're talking a million spectators minimum. It is said to be the largest motorsports event in the world, bar none, and it's all muscle cars, hotrods, and other gearhead doodah.) If anyone has any ideas, I am sure enough ready to listen.
