I have a vibration coming from the driveshaft area, I have replaced the fixed U Joints with removable U Joints, also replaced the center support, where else could it be coming from? Rear end is fairly new too. It is a GTS.
I'm not saying this is your problem, but i had the same thing happen to me. I had the vibration goin on, and replaced the U-joints. When putting the shaft back together, I did not have the half shaft in it's factory location, causing the vibration afterwards. What i mean is... the two shafts are balanced as one unit. If one shaft is not turned, or rotated to match the other exactly, they will be out of balance, causing the shaft to act like a U-joint or a carrier bearing is still going bad.
I had a shop here install the carrier bearing instead of Toyota, I will have them check that...thanks!!!
