TRNW-2: DIFF, GM Gov-lock unable to remove axle clips

[Chris and Cathy Kershaw]

Last one I did was a 13 with a cracked gov lock case. I seem to remember
the axle ends getting caught on the block. Like the block was falling out
of place just enough that the cut out for the axle to push in wasn’t lined
up. I had to pry the axles inward with a screwdriver in the clip groove
while wiggling the block. The speed sensor rings are rubber in the center
so not really a hammer type thing more like steady prybar pressure.
