The driver side rear axle shaft has twisted on me three times since I installed Superior chrome-moly shafts. Upon checking the axle shaft engagement into the diff. I foung the driver side to be about 3/8" less than the passenger side. The driver side splines only engage the diff. about 1" but according to the gentlemen I spoke to at Superior, that is sufficient. Has anyone had a similar experience? I know the shafts in a Dana 44 are not the same length and that the driver side is shorter than the passenger side so the problem can't be that they are installed backwards or the problem would be even worse. Thanks for any input you have.
