If it's a manual trans you can reverse the half-shafts, re-grease and go
another 140,000.  Color code the inside CV joints with spray paint before
disassembly.
Just unbolt them (without dropping them on your face) re-grease & bolt back
on the opposite sides. Now the bearing surface being worn going forward were
the ones only being used for reversing previously.  Clever, those Germans.
I wrote an article on this for the Transporter a few years back including a
detail of how to make your own "special tool" to easily reach the bolts for
the outer joints.
I can probably dig it up if you need more detailed input.
