U-joints propshaft replacement attempt

Well, I guess I was to optimistic about exchanging the u-joints. When jacking up the car I could get indeed easily reach the rear end. The front end however was mounted under a plate. Which I considered to much hassle to remove. Potentially the exhaust had to be taken off as well. So for this job a car lift is desired as well. When doing further checking I also found this interesting posting on the xjs forum:

Sounds like there is more inspection to do ...
