Hey everyone, been searching for this thread but cant find too much on it. Sorry if this is an obvious scenario.

I have a nasty drive line vibration after about 30 mph. It is only while i accelerate or have my foot on the gas. If I let off the gas it immediatly disapears. If I shift to neutral and coast its fine. It is a constant vibration and it gets so bad that i dont wanna push it past 50... 2WD seems a little worse than 4WD but either way its not normal. Its been lifted 3" for about a year now and this only started happening to this extent in the last 2 weeks. it used to have a slight vibe at 60 mph but never this bad.

Any ideas?

Also do I need a SYE with this little lift? some say yes, some say no...

Any info would be much appreciated.

x2 on the u joints
a pic of the drive shaft angle can tell a little more if you still need help. 3 inch is not a big lift and a tc drop would eliminate any vibes if that is the problem.

Thanks for the info. I will install a drop kit right away, and inspect my u-joints. Anything else i might have damaged that I should look into?
