There has been a lot of discussion on the Samba and the Snycro mailing
list about CV joint articulation and strength for those owners that
raise their vans and do heavy off roading. Various VC joins and axles
have been suggested.
  I've found a better solution, this German made driveshaft set up.It
allows extreme axle angles using stock CV joints
