Topic: weird vibration

[GBJeep]

I dont mind most vibrations in my Jeep, but this one is bothering me.  Bear with me on this as it is odd to explain.  What is happening is say you are at an intersection and you turn right.  Once into the turn I get a driveline vibration.  Only when the speed causes the Jeep to lean a little.  Also on medium to hard take offs I get this when the weight transfers to the back.  I can feel it on the floor boards and in the pedal.

What should I check out for this?

I appreciate the feedback.

Check to make sure your U-bolt straps are secure.

might be dumb question but do you have enough clearance for ur tires?  both of those situations could actually be the tires contacting the body

[GBJeep]

yeah, the tires are on stock wheels and only rub when the wheel is cranked all the way. 
Jeffy - sorry to sound dumb, but when you say ubolt straps I am not sure if i know exactly what you mean.  Can you expand on that for me?

Thanks for the relpys.

I should have said U-joint straps.  There are metal straps that are bolted to the pinion yoke.  Make sure those bolts are tight but don't over-tighten them.  I think they only require 18ft-lbs.  If those are loose then when your differential rotates under torque, it could be causing the problem you mentioned.
