Re: Shudder when accelerating over 90km/h
if it's a noise as well it could be diff noise, is it the stock diff?
my custom built 3.45 open diff with 28 spline axles and ed housing in my ea makes noise under accelleration from about 80km/h-92km/h but not when coasting at these speeds, nor below or above these speeds.... vibration on the other hand could be that you've broken a tooth or something in the diff but i suspect you would have discovered this while turning....
you're running a manual IIRC too, is it only in one gear that it does it? cos it might be the gearbox also...
