We have the same model of car I think, Nissan Xtrail I think right?
I used to have this problem with my car too. The wheel would start shaking at 100km/hr, continue all the way until around 110+ km/hr and only stop doing it when I hit 120km/hr. I think it's because the spoiler at that speed begins to pressure the car down and makes it stable just by way of aerodynamic stuff or whatever you call it, but that might be a wild theory.
So, getting pissed with the shaking, I got it sent for balancing and alignment only, no other stuff done. During that time the Nissan foreman said they only do low speed balancing up to 80 or 90km/hr. And he said he'd try to do a low balance first to see if it fixed the problem cos I usually do 110km/hr on Malaysian highways and that's the speed at which the vibration is worst.
In the end, the low speed balancing fixed it, but before we got it done the service rep told me if low speed balancing wouldn't fix it then high speed balancing at Stamford tires would, and whilst they were doing the low speed balancing I walked over to Stamford tires and sure enough one of their mechanics said the exact same thing to me, "You try the low speed one at Nissan first, if it doesn't work, you come over we do a high speed one for you"
Hope this information helps, I know how annoying a shaking steering wheel can be, having endured it myself.
