[100Kph Shuddering Like Im Getting Continuously Rearended =O]

Hey, no tires are all the same all round. Nissans usually use an equal width tire allround by design. Im going to try the on-off ignition method again tomorrow for longer. Going to look for a drivetrain expert in my area who may have a gem of wisdom about this.

[100Kph Shuddering Like Im Getting Continuously Rearended =O]

Guys, I just registered as Stagea info is few and far between on the net compared to Skyline. Forgive me if this issue has been raised in another thread, but I got to like page9 and thought

Here is my issue and it is a technical/mechanical one. Purchased my first Stagea, 4wd light was on solid. Began maintenance by topping up Attessa reservoir(righthand side of the boot). 4WD light went off. Driving specifically between 85-115kph, I would estimate, I have a shuddering or 'pulsing' sensation coming from what I believe to be the rear axle of the car. Like additional torque is being applied to the rear driveshafts momentarily in an on/off fashion. I would say that it is not a reducing speed sensation, as in abs acting on the rear wheels for some even more bizarre reason, especially as it only happens at a neutral or light load throttle position and the sensation is destinctly coming from the rear end. I have bled the attessa pump as per the instructions for a skyline except I couldnt find the plug to disconnect in teh drivers foot well like skylines are supposed to have. So we used a vacuum bleeder and me inside the car turning the ignition on and off to get pressure from the pump. Im will attempt to re-bleed tomorrow. We did loosen the nipple on the pump itself and had some drips to indicate no air but not entirely sure as it was the first time attempting to bleed an attessa system. Really hope someone can help. Any and all advice welcome
