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.

Since it been in the water. I would first dump some fluid in and drive it for a short time then change the fluid again and add the fricition modifier.
Thanks! Savvy. Now that you spelled that out for me in English..that makes sense now. I'll take your advice on changing the fluids. appreciate that!

Good observation. I don't know. To be honest, I don't know what I'm looking at. I did however sort of test it. I spun the pinion and both axles spin in the same direction. That tells me there is trac loc. But, I don't know. This stuff is greeek to me.

This axle is out of a 2004 LJ. After some more researching about the identification tags. It looks like I probably have limited slip. Because the right tag has the FM. Which I would say stands for "Friction Modifier" No?? Is this correct?? Couldn't you get the clutch pack from the stealership??

The recomendation to use friction modifier would indicate limited slip because the FM is to keep the clutches from chattering. But as I posted I don't see a clutch pack in that differential. so it's possible someone changed it to a standard open diff. Spin the pinion and have someone hold one of the axle shafts, if they can hold it and the other side spins, it's not limited slip.

oh I understand. Where would one find these clutch packs? Is it in the main diff there? Would they be in plain sight? thanks

I bought my Ospho at Ace hardware. I think most hardware stores sell something based on the phosphoric acid (Naval Jelly is another brand that has been around for a while), if I recall it might be in the cement/masonry area if not in the paint dept. Use good paint too. don't skimp there. You are going way deep into the prep I can tell that from the pics. Cool. have a good one and enjoy your axle. I thought about replacing the clutch packs in mine but decided to have a Truetrac installed during my gear change.

Awesome!! thanks dude. I'll be right next to a Ace hardware shop today to. cool. appreciate that. Do you know where the clutch packs are?? I don't want to add the friction modifier if these packs were removed and I don't have limited slip. Thanks for the help!

I could be wrong, one of your pictures looks like it might have clutches in it, the clutches would be behind the spiders. I can't post pictures, but here is a link to a page with some pictures of a trac lock in a Dana 35, and they point out the clutches.

Yup, after re-looking all the pictures, I'm pretty sure you DO have a Trac Lok, sorry if I caused you any grief.

Sweet! No grief at all man. No worries. Just trying to get confirmation. Looks like you confirmed. I looked at the pictures and the link you provided. Looks like I do have it. Thanks a lot, BJN644!!

It being an 04 it probably did not have too many miles on it so they are still probably good. Also The only reason you would need FM (friction modifier) is for the limited slip clutch pack so that another sign that you do have trac-lok.

I know there is a test to see if your limited slip is still in working order, its pretty simple too, ill try and find it and post back.

I haven't found that any clutch packs from the dealer, just the whole assembly, but if i ever do I will be sure to post it because I know of others who are also looking.

Good job on the price too, that a steal.

update: just finished up a round of wire brushin (see below). I can't get the rust out of the divot areas. Oh well. Its still coming out to my satisfaction. I took last night off. Can't really get much done with a little one. I did manage to work about 1.5 hours on it tonight.

I'm needing a disc brake system. Does anyone know if Jeep Liberty's disc brakes work on a 04 LJ dana 44??? or if there is any other Jeep that may work as well?? I been checking this used auto parts site...Car-Part.com--Used Auto Parts Market and I'm only coming up with Liberty's. Can't find anything on craigslist. Next up is dumpster diving at junk yards. I really don't want to have to shell out over 600 buks for a conversion kit...HELP!!!

Don't waste your money on a disk brake conversion. Just keep the drum brakes adjusted and they'll be every bit as good as disk.

Good deal and not too bad of a price. I was able to find one out of an annaversary ed TJ with a locker for $150 ready to bolt in. All it needed was a gear change but i sold the TJ before i did all that work. Holding onto it in case i end up bying my dads jeep after i sell my blazer. I almost bought a stripped housing for that much and i'm glad i waited.

I would take your advice but I do NOT have any brakes on this axle. So I might as well find a conversion somewhere. I just cannot find what system would work for a 2004 LJ Dana 44. Any body happen to know anything on this??? thank u

edit: What I meant is from a junkyard...what sort of Jeeps can I pull disc's system from?? or is it just LJ's and TJ's??
