Bad Vibes? Help

[PsychoticDeadGuy]

i just finished up my rear end completely now, or so i thought...i have some pretty bad vibes that go through the entire truck and i am not sure if it is the driveshaft or the rear tires? the vibes go all the way up through the steering wheel...it is only between 15-30 mph. what gives?

can anyone help out? how do you tell the difference between driveline or bad tire vibes?

What all was done to the rearend? Did you change tires? Did it have the vibration before you did the rearend? If you put the truck in neutral while it's moving does the vibration go away/get less?

i just swapped in a 14bff. it has stock springs and ord's zero rates and shackle flip. it is the stock driveshaft with the conversion u-joint in it. the tires were found off the road. they have weights on them but not too sure how accurate they are. i mostly want to know how to tell the difference between tire and driveline vibes...

Change tire press.
Try a different set of tires from another rig to see if it changes anything
