I have a re-buildable drive shaft supplied by motoren israel Germany I pull it out once a year and re grease everything as it has grease nipples to push grease into the bearings. The main reason the original shafts die is the bearings eventually dry out between 30 /50000 miles so it would make sense if they are re greased regularly they should not fail, maybe replace the bearings every 75000 miles as a safe guard. Much cheaper than replacing the driveshaft. They can be a bugger to get back into the shaft housing and seated on the bottom splines but patients pays eventually and they do go back together. I would say a better upgrade than the original simply because it can be repaired at the roadside - if you have a spare set of bearings.
