car seems to be running fine, i havent had any real problems, but when i get to ~47-55 mph the whole car shudders. its no in the steering wheel, theres nothing loose in the front wheel assembly at all, no ball joint or tie rod or loose bolts or anything. wheels are balanced. brakes are not out of round. it happens, when i accelerate, cruise, or decelerate. engine/tranny mounts are tight. resurfaced balanced flywheel. the only thing i can figure is my transmission, the input shaft bearing has been whiling for a while, although no fluid leaks out. any ideas?
