Mech/Luke, you and others are correct about the u joint as being a source that might be broken,it is broken on the rear yoke with about 1 inch being left on the propeller shaft, and about 1 half of it is all that is left on the spline, guess I will just replace the whole u joint from Jim Carter's,he gets $110 for the complete assembly,unless someone knows where I can get one cheaper. Thanks to everyone for their tips and concern. I almost drove Luke crazy with my e-mails,I may not be thru yet.......Fred
