I had to remove my driveshaft a number of times to repair a somewhat unique, prior repair. I was able to get a spanner in there. The thing I recall is that once you "broke" it loose, you could spin it by hand. I think I ended up removing it at least one time as one piece and at least another time as 2 seperate pieces. Make sure you mark the halves so that they go together like they did from the factory. Because my front piece (small piece) was totally different, i just randomly put it in, and it has worked fine.
