OK, I try to explain.
If you want to replace the bellow, you must open the black parts you see on the link, I've postet. These parts, I don't know the englisch name, so I call them Bell, are on this side which you stuck the drive shaft into the rear axle differantial and the wheel hub crimbed to the toothed axle. So if you want to disconect the tripod bearing spider wich is inside, you must open the flare and pull the bell down. then you can disconnect the tripod, pull the Bell and the bellow from the axle and replace the bellow with the new one. Now you have to replace the Bell too, but you never get the flaning so good as the original one. Also you have to replace the bell too. And here is the problem: I can't get a new Bell. So I look for a new drive shaft,
I hope i described the problem well
