grab each rear axle with your hand...
slide it left-right back and forth.
it should slide nicely. It 'has to' to function corretly. You can do
this with van on the ground.
next, ..jerk them up-down ...feeling and listening for play and dryness
in the CV's particularily the inners, as I believe they wear more and
sooner due to heat from the transmission area.
if they have play, or click sorta rattle..they're dry ..
and they could be pretty badly worn too.
I find dry ones commonly. I don't think the spec amount of grease is enough.
Original very high quality vanagon cv joint boots last nearly
indefentely in my experience..
so going by that the boot is still intact means there's adequate grease
on the balls in there is not a fair assumption.
if they rattle-click at all moving the axle up-down jerkily ..they are due.
usually choices are .............add grease and rotate/flip to a
not-badly worn CV joint to another position on the van .
or replace individual CV joints with good german, usually Lobro brand,
new ones - ---works for me.
