hey guys only just started happening out of the blue, anything under 95k's a hour and the car is perfect, handles well stops well no noise/shudder from brakeing. as soon as i hit 100 or over, steering wheel slighly shudders its only slightly but im just curious what can cause this as i dont feel too safe driving it atm.
As East Coast said, check wheel balance as you may have dropped a weight off one of your front wheels, also check around the walls of the tyres for any possible swelling indicating separation from the inner wall tread or maybe even a slight swelling on the main tread.
have had them all balanced, also have had my rotors machined on the car as some people recomended to me tryed a diffrent known pair or rims/tyres to confirm that this is not the cause and persists
had a bit of time today ripped the rear wheels off and had a look at the tie rod ends, i can wobble the rear wheels maby 1mm, is this normal or should they be 100% unable to move unless hicas is engaged ?
Why are you checking the rear end, when you were talking about the steering wheel in your original post?

Have a read of the Nissan FSM, Section RA (Rear Axle). Various specifications are listed at the end of the section. In relation to the tie rods, 0mm clearance measured vertically is specified. It can be difficult to identify the source of movement in steering & suspension systems especially if all the wheels are off the ground. It is a lot easier if you have assistance available to either wobble or observe components. Also tools such as magnetic based dial indicators can make diagnosis easier.
Fair enough, however to solve issues it's best to "stay on track" with your questions & comments. Otherwise it becomes misleading & confusing. Vibration felt through the steering wheel is usually confined to something related to the front end, either tyres, braking or suspension systems. To solve this issue is a process of elimination, you are on the right track changing wheels, having them balanced & machining rotors etc. Once again refer to the FSM. Are you testing on the same section of road? Sometimes road surface condition can be felt through the steering wheel giving the impression that the wheels are out of balance.
Is it definitely only through the steering wheel, or through the whole vehicle? Could be center drive shaft bearing if you're actually feeling it through the whole car. If only the wheel. Look at the wheel balancing and or the rims. No buckles or anything? Didnt hit any large pot holes.
My suggestions, since you've already done balancing... If you have after market wheels, make sure you have hub centric rings. Make sure your tyre pressure is adequate for the weight of the car. Make sure there isn't bad run out on the front of your tyres, even if they're balanced, they can still be shaky as crap and wobble your steering wheel.
I had a similar problem and it turned out to be the tension rods. One of them was badly leaking. replaced it and the issue went away!
