<VV> Diff Still Blowing Lube Out Vent

[Mikeamauro at aol.com]

Hello Dan:
 
Thanks for the reply.
 
Re:
 
"...Is the vent on yours toward the driver's front of the cover  or
passenger rear?..."
 
Mine is the newer design: driver's front.
 
" ... Is it possible that at one time, the carrier bearings were  replaced
via the method described in the GM shop manual?  They recommend  drilling
holes behind the bearing cups and using a drift to tap them out and  then
plugging the holes with lead.  Could it be coming from  there? ..."
 
After a hard highway run, there is gear lube pooled on top of  the cover; the 
leakage is definitely coming from the vent.
 
Any other ideas?
 
Thanks again,
Mike Mauro
