Samsung front loader

I replaced the tub shaft spider in this machine about two weeks ago (part acquired from you folks),the machine has been working fine until yesterday.Put in a load and during the final high speed spin at 6 minutes to go it stopped spinning and put 11 minutes on the timer and started jogging the tub back and forth but would not make a revaluation.I can use different cycles and the water fills but tub just jogs now.PLEASE HELP!!!
