Without hearing it, here's my guess,

The power steering pump will groan if you hold the steering wheel all the
way against the lock too long. Power steering pumps have a pressure relief
valve that opens under extreme pressure, and it will make a groaning sound
when it opens. This is to keep you from blowing the hoses off, when you hold
the wheel TOO tight against a turn.

Try reducing the "tightness" of your turn by not turning quite to the lock,
and see if the sound goes away.

Just a guess.

Adding a second course of additive should be fine. Folks say some of
them even need it if the fluid comes premixed like lots do.

The "groan" I hear on tight turns is the tire rubbing on my Real
springs. See if your strut is polished from your tire, if so and it
still bothers you adjust that wheel's stop:

This is a common problem with Quadra-Drive systems.

When the wheels turn at different speeds in a tight
turn, the system will react as if the wheels are
slipping and pressure builds up against clutch plates
in the diffs and t-case to put power on the wheel that
is not "loosing traction." You will hear the system
working and you may feel a bit of vibration as the
clutchs shift power around. If that is the case then
you can chalk it up to normal. If you are getting a
shuddering/jerking, then you need to have the tcase and
the diffs worked on or at least looked over to see if
any TSBs apply to you.

DC put our several TSBs regarding swapping out the guts
of the "gerotors" in the pumpkins with chrome plated
versions and about making sure you have the limited slip
additive in them and only putting the from-Mopar-only
yellowish made just for the NV-247/249 goo in the t-case
(do not use ATF of any kind--early WJs had ATF from the
factory and those all had to be flushed out).

You might want to check out www.wjjeeps.com. They have
all the TSBs as far as I know. If you are still under
warranty, GET THEM ALL DONE *NOW*.... Read the TSBs and
if you have any of the mentioned symptoms, take it in.

Do NOT be afraid to wave the TSBs at the dealer. Once
they know that you know about the TSBs, they are less
likely to try stonewalling you. If they do give you
pushback, take it to another dealer who will not mind
charging D-C for warranty work.

There have been many complaints that it does not work
as advertised. If you want to read about them, do a
Google search. The basic gist of it was that Chrysler
took a performace claim from the OEM and blew it all
out of proportion to reality.

The thing is really great at high speeds on roads with
2 inches of water on them--one wet freeway in WA had tire
grooves full of water that I was just fine in but everyone
else seemed to have issues.

At low speeds, there have been situations when the system
totaly failed. Someone in Austrailia did a test where he
jacked up three wheels and it failed to send power to the
wheel still on the floor... I had one problem at Oceano
dunes with a WJ fully loaded down with camping gear, but I
attributed it to the car being full and me being lazy by no
airing down before going into the more "Arrakis-like" areas.
