Front End/steerling wheel Vibration

2003 xcab, 4x4 v6 5speed. 3inch AAL, bilston HD struts on the front. Idk what kinda coils are wraped around them. (Junk yard find ) Sits abut 2 nd half inches higher then stock.

I've got front end vibes and it's driving me crazy.. So far this is where I'm at with it.

I can feel it in my steering wheel, dashboard and slightly on the floor. Feelings like it's coming from my front passanger tire.

It only happens at 15-50mph when I'm accelerating and seems to go away if I take it up around 4000-5000rpm and I get the same vibes letting off the gas while still in gear.

If I throw it in neutral the vibes go completly away. Every gear and speed.

On the highway it feels super smooth in 5th gear, zero vibes.
4th gear above 50mph the vibes start to go away. 60mph-80mph I can no vibes while in 5th gear.

Got brand new tiers on my truck, put the stock ones back on, same vibes.
I put my friends taco driveshaft on there. Same vibes.

replaced the ujoints and carrie bearing. The rear end feels smooth, I'm 99% sure it's not from the half shaft back.

I Got my truck on a patch of ice, spun out. Same vibes as if I was driving down the road...so I'm guessing it's nothing on my front end? ie wheeling bearings.

Also put the truck in gear while I had the drivelines off, put it up to speed and had no vibes.

Sooooooo I'm thinking it's either a bad motor mount?? Output shaft bearing??

no vibes parked while reving either

 

Flywheel maybe?? pressure plate?? Lost here.

Put the rear of the truck on jackstands, my transmission jumps up and down.

Any input ?
