sure this thread is a little old, did you ever resolve your problem? I checked my center driveshaft support bearing and there seems to be a lot of play. I was quoted about $100 for a Nissan center bearing replacement "kit"(online price) but you mention the bearing won't come off over the ujoints?
I get a vibration in the gas pedal/shift knob- it seems the vibration is from something vibrating the firewall or floor pan ( bearing bolts underneath)
