I did the grease needle thing on my van a year ago and
then took the van to Egypt for a year.  Upon returning to
Halifax, my trusted mechanic poked around in one of the
CV joints and found packed SAND all over the place.  He
pulled the other 3 CV boots and same thing, SAND
packed in the grease.  All of this from a tiny needle hole
(but used in punishing conditions - desert sand).

When I/we first did the grease needle thing, we/I did NOT
try and seal the holes with any sealant.  I doubt that I do
the grease needle thing again except for an "emergency"
to get back home then do it properly.  m2cw,  Malcolm
