Hello all you nice Buick people, I have purchased my first Buick, a 1949 Super Sedanete I have always had Cadillac and LaSalles, This sure one fine automobile, It is a two owner and has had some restoration done to it , I would say A very good professional job. However The torque ball seal leakes, I have done 54 Chevys before with the enclosed D.L. I cannot get this rear end to roll back.I have disconnected everything that is necessary and that darn rear end is as solid as ever, Moves sideways but not back, It acts like the pinion splines are frozen in the U Joint. That could be the only place that is keeping it from sliding back, I need some help , I appreciate it. Looking forward to discussing this , Thanks steve
