Long time since I've seen one of those!! 30 years maybe. In my case, it became known as the self repairing half shaft. Bought 'new' from a supplier no longer with us, the joint failed after less than 15 miles. Towed home and then when putting the car back in the garage, drive had fully restored. Half shaft removed and replaced and the car went fine. The removed 'new' half shaft looked like someone had but a shallow 1/8" wide groove at about mid length. It was some months and many looks by lots of folk until the cause was found. Like yours, it had had a new end fitted and as the joint failed and the new end moved out of the old end, the overall length of the shaft had increased and locked the diff restoring drive. Towing home and the friction between the two halves had caused them to weld together. Don't know where you bought your half shaft from but I think I might know the original source. Was it maybe from some old stock bought as a job lot at auction?
