I have a Whirlpool Model 6D25DDXFW00, Serial 564630908 that when the agitator is turned on the whole ice container vibrates and jumps so bad it actually will start to open the door. The motor or fork that drives the container appears to be very strong and not slipping. I tried to order a new complete container and it came in without the bar and pieces to turn the blades at the end of the shaft used to go from Crushed or Cubed. I have found one on a web site that appears to be the correct one but don't want to spend 110.00 if its not going to fix the problem. Any help would be greatly appreciated.
