I have the same problem with my 2002 LeSabre, at 70 mph, no less no more. I always have. I have replaced both front axles, sway bar linkage, tierods, muliple alignments and new tires. BuickLesabre is right. The shaking is not in the steering wheel at all, it is in the seat, it is the whole car. I am begining to think it might be from the back wheels. I notice when going straight, very slowly (10mph) on a smooth road the car woobles side to side.
