I am trying to replace the cv axles on an 87 accord. The driver's side came off as it should with a gentle pry at differential. The passenger's side was a bear. No matter what, I could not pry the shaft from the differential. Quit when I thought I was going to crack the case. In my mind I am thinking the clip ring has slipped or someone has been there before and used the wrong size? Am I missing something?

Thanks,
Michael
