Went to change the spider/side gears in my 88 Camaro,
and found that the lock bolt for the spider gear shaft
(what GM calls the "pinion shaft") was broken. Bummer.
This bolt apparently is a problem child in that it can break
on its own from constant hammering of the "pinion shaft".
Anyways, I've documented an easy way to remove the
broken half of the bolt in the carrier in case anyone runs
into this. http://www.tinyurl.com/ywpu5
