Well after several hours working on the truck over the weekend here's what I looked at or changed. I changed front and rear diff fluid, switched front tires from side to side and also removed and cleaned the brake pad sliders and pins in the caliper. Took it for a drive and the vibration is gone! It was pulling to the right and after I did this work and it went away as well. Now my question is can a change of rear diff fluid help a vibration possibly caused by a posi rear end maybe "hanging up"? I used Amsoil gear lube and their additive for posi rear ends. I am still going to have the driveshaft checked and the tires radial force balanced just for peace of mind and get a better balance on the tires. Hopefully the vibration is gone for good. I am also going to lube up the rear brake sliders and pins as well(it can't hurt at this point).
