ok, i have an 88 k5 and everytime i let on and off the gas i get a grinding sound and a vibration from in between the seats. everything starts out at about 35 mph and gets worse as you go faster. it will fade away and coast fine after a couple of seconds. the u-joints and driveshaft all check out, and the fluids all show no sign of metal. the only thing i can think of is maybe the rear axel bearings, something broke in my diferential, of driveshaft slop that was overlooked. any thoughts???
