I have a 1960 and the left rear axle seal is leaking. I used the bearing and seal kit, which is an integral replacement unit (SKF RW607BR), to repair the leaking seal. Unfortunately, it leaked again. Did the repair a second time with another new unit and again, it leaked. I’m told the bearing/seal units are all made off shore and lack quality control. This is a problem. There has to be a solution out there. Axle is straight and not pitted at seal contact. Is anyone aware of this issue or know of a solution? Cheers
