[Vwdiesel] CV axle problems

[Gavrik Peterson]

Last night I finished disassembling and my drive shafts.

I noticed that the grease that was actually in the joints was way
thicker and less mobile then new grease.  Also, there was grease that
was on the inside of the boot that was thinner and more runny then new
grease.  It looks like some fluid component of the grease separated
out and left the joint and was thrown out toward the boot.

The stuff I used was Red Line CV-2 Synthetic.  I am wondering if the
Amsoil Synthetic grease holds up any better?  Any comments?
