If you watch my video a few times you will notice that my axle wrap isnt bad. Its just enough to cause the wobbling acceleration and vibration when on the gas. It feels as almost on take off my wheels are hopping and on a turn near my house you can really feel it when you take off from one road and onto another. If you take off period you can see my transfercase lever wobble left to right, on the gas easy with no torque really and no issue.

I have checked every mount, replaced the trans mount, replaced the carrier bearing, checked my tires and rims, had the driveshaft balanced, had the u joints checked over and over and I have even checked the frame among other things.

The leaf springs are worn out, thus I am getting very slight over movement of what one should normally have. I have 200k on the truck itself, the PO towed his boat a bit and hauled some heavy stuff in the past. I hauled a boat and put a 500lb atv in there a number of times.

If new/re-arched springs dont help I dont know wtf to do anymore. I have done everything imaginable, had it checked by friends who are mechanics, paid the driveshaft guy and my own mechanic and no one can conclusively say anything besides my mechanic who feels its axle wrap.

Watch the video again, notice when I take off and am on the gas the pinion moves ALOT upwards. If the springs werent worn out, it wouldnt move nearly as much and when I am off the gas the truck coasts no problem.
