I opened my rear diff cover (10 bolt) so I can replace a leaking axle seal. I thought I had an open diff, but I think its a gov-lock. My question is do I need to remove anything besides the retaining bolt and cross pin to remove the c-clip? I was fighting with it for about 10 mins trying to get the c-clip out, but no good. Any tips? Thanks BTW: I did search prior to this post. I was doing a search and someone mentioned a "block" that the cross pin goes through?
