Getting some bad vibes...

Vehicle is a 05 f350. Ive got a 10" lifts on 40s.

I have a few vibration problems that I NEED to address as it is driving me nuts.

One is a vibration at around 50-60mph. I'm thinking maybe a wheel is out of balance? Any other things would contribute to this that I should be checking?

Another is on initial take off, I get the axle wrap shake. I bought a set of procomp traction bars and I dont think its doing anything for me, I dont have a tuner or any major engine mods. Could anyone suggest a sure fire way to fix this? OUO traction bars?

Any suggestions are well appreciated...
Thanks in advance!

What should I check about this carrier bearing. Carrier bearing has been dropped down and the driveshaft i almost perfectly stright, but it doesnt rule out the ends eg. at the dif and trans? Is there some sort of rule of thumb to follow in regards to this? I heard I can get blocks to rotate the diff a little bit?

You can buy blocks milled at an angle to point the diff up slightly and decrease the angle on your U-joint. I had the same vibration on my truck (but it's stock) and after shimming the carrier bearing down it was gone.
