Vibration after lift

Installed a rough country 3” lift, and i get a vibration at lower speeds feels really noticeable when accelerating or braking between 25-30 mph, it will go away around 45-50, can’t pin point what it is just curious if anyone can point me in the right direction

 

Could be the drive shaft (angle).

 

Swap out the needle bearing? Does it go away in 4x4?

 

If you put it into 4wd and it goes away, it’s your front diff needle bearing. Gotta swap it out.

if not, can be your driveshaft angle. Your driveshaft is supposed to be at a specific angle. Not that you lifted your truck, the angle is going to be more aggressive. some people put wedges under thier leaf springs to fix the angles. Some use a spacer on the carrier bearing.

 

no 4X4 so I’m gonna try some wedges underneath the leaf springs and see if it corrects it
