Yeah, if it does have a limited slip (trac-lok) from the factory then it will have a clutch pack. (which some peoples wear out after 60,000 miles) Mine is still hanging in there at 95,000 miles but that because I drive like an old person on road. I have been searching for the clutch pack (not the whole trac-lok assembly) for when mine finally gives up, but its tough to find. Most people will say "o just get a Detroit True Trac, its a ton better than your trac-lok and it is gear driven so you don't have to worry about the clutch packs" but I don't have $500 screaming to get out of my wallet.
If the d44 is out of an earlier TJ then it will have trac-lok because it was standard w/ the d44 option, but later models the trac-lok became an option, and was not standard w/ the d44's. So if you find you do have a limited slip make sure you swing by the dealer and get the additive (friction modifier) for it, its about $5.
Hope this helps.
