To all any input would be appreciated, while in 2wd no squeek/squeal, in 4wd there is a squeek/squeal noise sounds like it is comimg from the front, all ujoints seem fine.

 

only thing that is going to change between 2wd and 4wd, is going to be the front driveshaft, pinion, gears in diff, and you CAD is engaging the shaft in front axle. is the sound constant? does it change as speed changes?

 

Sound is constant and it does not change with speed

 

You did check the ones by the front wheels correct(axle shaft)? Not just the cv drive shaft ones.
Mine where trash at 60K (no needle bearings left in them).

 

u-joints will create a popping sound not a squeal. since it doesnt change with speed, it sounds like its not to do with the rotation of anything, you sure the sound aint coming from the transfer case?

 

Yes also they were replaced 20k ago I put in the greaseable ones

 

Idk how would I check?

 

Even the transfer case, if it were the source of the noise, would change with speed. Do you hear it when you are stopped, or only when moving?

 

Only when moving

 

Then it's gotta be something in the drivetrain.
