I took the belly pan off the 190D 5-SP and found the part # 2014112147 ( Propshaft joint ) all dis-integrated.

1) What is this part ? Can it be replaced with a flex disk? pic 1
2) Also I can see the spline at the other end of the shaft. It looks like it is 'shifted', is this a problem? pic 2

See pictures below. 2014112147 shows as Propshaft in most foreign web-site when I google it. The dealership said it is a bad number ??
