Driveshaft Variations
(January 01, 2017)With all the variations out there available to run on a VW this information might be helpful to some.
The Bug spline length is not long enough to use the Type 2/Type 4 CV's without milling the shoulder down for snap ring clearance.
If the machining is done, the axle will be weaker and can snap right in that area.
The Type 2 and Type 4 CV's have the same width center cage (28mm), so they are basically interchangeable between each other's axles and no need for milling.
Bus = 18-3/4" long Bus = 34mm
Bug = 16-5/16" Bug = 28mm
Porsche/181 = 16-1/8" Porsche/181 = 33mm
