... there was one on the u-joint on my V8's propshaft, which is also hidden
behind the exhaust system and a heat shield.  Memory's a bit fuzzy, but I
think I could access the fitting with the exhaust intact, but in any case it
wasn't that tough to separate the exhaust to access it [as I found with the
QTC it appears that Audi put a little thought into service when they
designed the exhaust for this car].  Lubing the u-joint calmed my car's
tendency for driveline vibration under power.  

BTW, I too have had to adjust the orientation of the fitting to make access
for the grease pump easier.  

HTH!
