Re: Truck Rear End Needed

You need to watch the GM differentials as there is a service bulletin
that only dealers know about.  For many years in the 80s GM used too
soft a steel for the axle shafts and as a result the ends would wear
down to the point that the clips would pop off and then an axle would
slip out of the housing.  The service bulletin had specifications for
wear and once the limit was met then the axles met the specification
for warrantee replacement.  The problem was with all GMs not a
specific model.........even seen the problem in some TT Corvets.

As for the nine inch Ford that is the way I went for the Toyota Tcab
and it fits just fine.  Pulled the differential out of a mid 80s Heavy
Half ton.
