As long as the outer assembly fits the hub. I purchased a couple a while back, and when I went to install them, the flange wouldn't fit in the hub. It took a couple of sets to get it right, but these 1/2 shafts had a "lifetime guarantee" on them, so I played that card as long as I could.
Seriously, I travel with a full set of 1/2 shafts as spares. After the season, the 1/2 shafts and hubs are replaced with the spares, and the old ones are either replaced or rebuilt.
You can rebuild your own 1/2 shafts with kits, grease, boots, etc. but not all of us have the capability/hardware required to replace the bearings in the hubs.
