Driveline Vibration? Help!!
Hi guys
When I am driving my car at about 40-50mph and put the pedal at half throttle I get this vibration that comes from below me it doesent stop until I let off the gas. Could this be the driveshaft? Please help. :confused:

Hmmm, only under load is what you mean. The vibe isn't there when coasting or decelerating at that RPM/MPH? You sure it isn't just resonance?? Any shake in the wheel at all??

No shake at the wheel. The vibration only occures when I accelerate form a certin speed like 40. But when I accelerate from other speeds like 5,20,30 there is no vibration :confused:
Thanks for the reply

Driveline vibrations are tough to diagnose. Especially via the internet :yesnod:
But first I'd check U-joints. The C4 has six of them. Also loose transmission to differential mount bolts can do it.
Good luck, Tom
