mopar shop/electrician in AZ, Phoenix area???

Yeah i replaced the u joints. Left the alignment of the knuckles the same but still a vibe. I doubt its the problem but I am going to balance the drive shaft next. I tried to balance the tires but no one would cause they are so old. So I'm gunna get some new rubber for it if the dshaft balance doesn't help. Motor and trans mounts all look good too. ..
