Notice a vibration at 80 mph+up while cruising but not when hard accelerating at or beyond that etc. u joints look and feel solid ,tires are new and high speed balanced- Drive shaft itself -have the steel one.Go alluminum or one thats balanced with the yokes on etc?

drive shaft could need balenced... make sure your alignment is good and everything is torqued down...

What a nightmare. Definately in the shaft ,I feel it right around 3/4 point of the car have to check it to see if i lost a weight or something. thanks
