Question about 2004 Chevrolet Venture Passanger
On smooth road, the van will sometimes vibrate at around 40 to 45mph. I have recently replaced the tires with no effect on the vibration. I returned to the tire shop, they rechecked the tire balance (was good) and checked the alignment (was found to be in spec). I suspect that Torque Converter Clutch engagement is contributing to the problem, but the vibration will not disappear completely when going down a slight grade with foot off the gas pedal (which should release the Torque Converter Clutch) and trans shifted to Neutral. Any ideas would be appreciated.
First, if the milage is high it could be a cv halfshaft even if the boots are not split. if the tires are new and no rims are bent, make sure there is no fix -a- flat in the tires, (liquid will not balance) and cause a severe vibration. i would suggest you take it back to your shop and have them put it on a lift, raise up the front wheels under the outer part of the lower control arm where the front is not hanging down too far and start the vehicle. run it up to 45mph to 60mph and have them feel in the drivetrain for vibrations and shakes.if it is felt with the car this way the vibration is in the drivtrain. inner cv's or in the transmission. thanks and let me know what you find out.
