help my truck feels like its on rumble strips

[macknos94]

OOk so I got me whole truck together and running but now when I cruise along it rides fine. Then when I give it extra gas to go up a hill or make a left turn it feels like I'm driving on rumble strips. It has never done this before my upper uniball took a crap.the new Axle is seated in the front dif and I did the install just like any other I do. Anyone have any ideas?

My 95 does that too! It only does it when I let off the gas from doing 70-80 mph. I actually thought I was on the rumble strips when I first got it

But mine does it at all speeds as long as I give it gas. It's almost like my transfer case is taking a crap

Maybe universal joints?

Man thats sucks, hope you get it fixed soon! I can't wait to see your ride, I want to see how high that thing sits with a body lift and RB spacers!
