Hey guys! Just joined, but long time reader. Need some help
I just bought a 2004 f250 ex cab 6.0. When coming from a stop
My truck vibrates from 5 to 20 mph. The truck has a lift with 37 and
Thought the vibration was the tires but its not. Seems to be coming
From drivetrain I think. Checked oil in rear diff and its good. Not sure if
U-joints would do this? It's only in 1 and beginning of 2 gear.
I'm stumped any help would be awesome!
Thanks, jake!

Could it be axle wrap? How about some info about
What it feels like and stuff. It does not shake coming to a
Stop that's why I believe it's got to be somethig in the drivetrain.

 

Is it the whole truck that vibrates or does it just feel like the front end is vibrating from take off? Every lifted truck ive owned has had some shake but its mild. Wouldnt hurt checking everything in your suspension to see if its loose. ball joints, tie rods...

 

With 37's on the short wheelbase, it's either axle wrap or the carrier bearing needs to be spaced down more. What's the pinion angle look like? Not terribly uncommon.
