The rear axle drive shafts and joint flanges closest to the transmission, have received a modified sealing. A new end cap, which is pressed on to the CV
joint, is used for sealing this (new) version.
The flat gasket formerly used is now omitted, as well as the recess for the gasket (arrow) in the transmission flange.
In addition, the new CV joint is shorter, with a total width of 31 mm previously 43 mm, the bolts were shortened by 7 mm.
Bolts:
New - M10X50 mm
Old - M10X57 mm
