vibration

i don't think it is the tires before i put new tires on the truck the vib was their. the old tires where so worn out i though new tires would fix the problem. the new tires have been static balance weights on the inside of the tire. when i go in to get them rotated and balance they can put the weights on the out side of the tire. but i do need to check my brakes out i will check the tire spin when its up on jack stands.. thanks for your help

If you have a bent wheel or a bent axle flange, new tires is not a possible fix! Yes you may have a drive shaft that could have a stiffened joint,such as on the front of the drive shaft,and the rear extension housing bushing, may be worn on the transmission. A stiff or rusted u joint bearing cup may be causing a higher speed vibration. I dont see this causeing any steering wheel shake.Before you Remove the drive shaft,mark a spot on the shaft to a spot on the differintial pinion flange,so you wont install it 180 out,this in itself may cause a vibration,at higher road speeds.If the front yoke doesn't swivel in a smooth circular motion then the cups on the joint are not free to opperate properly.
