JR,
At last falls GMCMI Convention in Elkhart, Dave showed me that the Chicago Rawhide / SKF 21771 had problems as well which is why he
found a source that was OK and produced the installation tool.

This issue was originally brought up by Dave Lenzi at the Fall 2010 DuQuoin
Convention where he had discovered several sets of rear bearings had an
issue with metal in the grease. Dave said there were 2 manufactures that
were OK. They are the Chicago Rawhide 3857731 and the SKF 21771. The SKF
is sold by NAPA.
