Need a little more info, when your going 55 if you press on clutch or put into neutral does the vibration go away? Does it vibrate under power or at cruise? There could be several different problems, tires, u-joints, pinion bearing, drive shaft.

Highly unlikely to be the shaft. They don't usually just start being unbalanced one day out of nowhere.

First thing you should check is that the tires are balanced. Inspect the rear shocks as well (look for evidence that the internal seal is blown, meaning oil or oily residue on the lower half of the shock), and also suspect bad U-joint(s).

Issues like this are almost always attributable to wearing parts. The driveshaft is not considered a "wearing part". Unless when you get under there you see obvious damage or irregularity to the driveshaft, I wouldn't even consider it as a possibility. Those balancing weights don't just come off unintentionally.

i got it fixed. :bounce2: if anybody has the same problem just make sure your driveshaft bolts to the rear end are tight. they like working loose.

^ Probably not a bad idea to install those flange bolts with a little bit of Loctite on them.
