weird vibration/pulsating

yo, just bought a 2015 offroad, and noticed that when I am going around 40-45 mph, there is a small vibration, almost a pulsating, that I can hear, and feel through the gas pedal. Anyone heard of this?

 

Lifted?

 

came with a small spacer upfront, just a level, about 1.5"

 

Might be the needle bearing the in front diff. Someone with a second gen with chime in.

 

that a problem? or just something that needs to be tightened?

EAst Coast Gear Supply has a replacement part and tool to fix it.

You’ll know if it’s the issue if it goes away when you put it in 4H and go the same speeds.

Cause is the needle bearing after a lift if as mentioned above the issue goes away when in 4H. Ask those of us how we know

 

Check the small things first like tires and tire pressure also make sure u joints have been lubed.
