Before the CV axles can be installed, they must be shortened slightly. This is accomplished by tapping down on the flange on one end until the cover plate pops off: 
 
Then remove the circlip, place some tape around the ball bearings so that they don’t fall out, reverse the ball assembly on the shaft, and finally reinstall the circlip: 
 
The end cap then can be tapped back on, and the shafts are ready to install. 
  
I dug this up on another website and was curious if this relevant to my issue. He shortened the half shaft  so could i lengthen them so they are not pulling out?
