I opened up the diff in the summer checked for play everything was good its when I get wheel hop in the front the driver side axle snaps instantly when I'm off roading I don't know why I get wheel hop my hole truck shakes like death wobble but I'm not moving I'm trying to move and every hops when I'm driving down the road in 4x4 everything is fine I have no issues only when I'm in snow or sand front end starts to hop like crazy

 

Put the front up on jack stands, shift in 4wd, try and turn the passenger front wheel BY HAND. See what it feels like.

 

Alright the reported hopping is a concern. Axle hop will blow up a u-joint pretty quickly. It's possible it's always the driver side because there's less twist (cushion) available with the shorter axle.

I'd look at all TRE's and maybe steering box. When the front wheels pull if anything is loose they can try to go in different directions (if TRE's) or both go back and forth in unison (if steering box or steering shaft).

How does the truck drive on dry pavement in 2hi?

I don't think loose steering components are actually the culprit, but worth considering. I'm actually wondering about axle wrap. How are control arm bushings?? We tend to only think of axle wrap on rear axles but the front also needs to be solidly located

 

Since you're off-roading in this truck, what modifications have been made to the front end? What size tires? Has the truck been lifted at all? If so, how much lift and how was the lift done? Are the front wheels properly balanced?

Sounds like something is binding. As was mentioned, put the truck up in the air on jack stands. Once in the air, have someone inside the truck turn the steering side-to-side while you are under the truck looking for front end issues (binding in the front U-joints, bad/loose front end parts, etc.). Also, check the track bar to ensure it's not allowing the front axle to move around. What kind of front wheels are you using with the taller tires? Is the inside of the front tire rubbing against anything while turning/moving?

 

I ha e duratracs on my truck has brand new Trac bar everything on my front end is brand new my tires rub when I turn all the way yes but when the axle blows I am driving straight and I get wheel hop and boom u joint explodes and axle eats it

 

The parts you have on the front end may be new, but may not be holding up well with your off-roading activities or may be bad out of the box. You're going to have to make the repairs and re-check everything in the front end to ensure this issue is resolved and won't happen again. You might also consider taking the truck to a driveline shop for a professional look to see what's going on.

 

This. I'd personally chase the wheel hop issue as that is not normal.

OP is going to have to re-trace his steps. Just saying that every component is new is not helping.

 

Additional, more detailed photos of the front diff, track bar and front end components (tie rod ends, drag link, springs & shocks) would be helpful to view in this post and may trigger some thoughts of other things to check...
