05 Z1 steering wheel violently shakes in 4wd

[jollygreen6456]

05 Z71 156k miles, has 3 inch rc leveling kit. When you put in 4wd and gas it decently the steering wheel shakes left and right and makes it uncontrollable to steer. Almost feels like the front wheels are going inward and I can't imagine it being good on the tie rods. Looking at it it from different perspectives we've narrowed it down to possibly the clutches slipping in the transfer case or that the backend is just squatting way to much causing the front wheels to spin he (my dad) didn't replacethe rear springs when he lifted/leveled. Thinking right now order cargo springs because it would trailer better and add stiffness to the rear. Anyone have insight would be greatly appreciated just put new tires on it and don't want to take it wheeling like this.

axles might be bad up front. or the lift messed with the geometry real bad and they are binding up.

I'm almost sure he replaced the cv's. If not aren't the 07 cv's an inch or so longer and direct fit?
