What's the difference between a dedicated CV grease and, say, a "high temp
disc brake wheel bearing" grease?
   Are my wheels going to fall off because I shot 15 pumps (htwb grease)
each, from my grease gun, into all four of my axle boots?  15 pumps (x4)
used up ~one pint of high temp WB grease... The joints are now much
happier....but did I create a caustic mix with the two greases, something
that is eating those CVs?  No time to do a complete service right now,
therefore the short cut and "grease I had"...
