No, you don't use circlip pliers on the clips inside the diff. There is a tab opposite the opening on the clip that you pull. The tab has a hole in it so you have something to grab. So you put a wire through the hole and simply pull the clip out. Now here's the secret: drape a towel over the area so the clip doesn't fly away. Mine flew at least 10 feet across the garage and took me 15 minutes to find. Not a fun time!

Edit, after rereading Jeff's post I see how he meant to use the circlip pliers. But they really aren't the right tool for the job.
