Good advice Mike!
I dug up my owners manual and it does say to use
a friction modifier for the Dana 44 with Trac-lok.
I also have a FSM for my older 01TJ and in it, It also says
to use a friction modifier with the Dana 44 with Trak-lok.
Not sure why a lot of people say it doesn't need it, when in fact
the manual says it does.
Gotta order a FSM for my 05TJ Rubie to remove all doubt.
Cheers

The D44 w/ Trac-Lok (that you mention below) and the Rubicon's D44 with
the Tru-Lok are two completely different limited slip systems. The
clutch based Trac-Lok needs the modifier and the helical gear based
Tru-Lok does not.

Thanks for pointing that out. I'll have to look closer at the manual
I have a copy of the 05TJ specs. This is the list which tells you which
model has standard or optional equipment
They certainly are confusing.
In one place under "axel" it says it has the D44 with Trac-loc
and under the another place under "differential" it says it has the
locking diff with helical-gear limited slip unit.

If you have a Rubicon, you have the Tru-Lok and do not need the
modifier. That is a fact and you need not go any further. Other TJs that
got the optional D44/Trac-Lok have a clutch based system. Most of these
'manuals' cover more than one trim line and I think that is what is
confusing you.
