High-Speed Vibration

tsupranami · 02-12-2009, 08:01 AM

I've got that vibey feeling too.

Check wheels and tires. Jack up the rear of the car, support with sturdy stands, block front wheels, and run the car in gear and watch the tire/wheel assembly for out-of-round, lateral or radial. Check the driveshaft center support bearing for play (up/down, side/side). Any runout in the tires or play in the driveshaft will amplify vibrations at greater speeds.

I just installed the one piece AL driveshaft. I'm not sure it has helped the vibe issue at all. It does get rid of the clunk during shifts and when starting from a stop, though. Gonna check my tires/wheels again.
